For steel-constructed TV towers, complex aerodynamic profiles and low damping are typical characteristics—two attributes that render wind-induced response and wind load critical considerations in their design. Additionally, their wide distribution across diverse terrains exposes these structures to varied wind conditions, further complicating wind-resistant design efforts. To explore how wind field parameters affect wind load and wind-induced response, this study took a 240-m-high TV tower as the engineering background, simulated different turbulent wind fields in a wind tunnel, conducted force measurement tests using a high-frequency dynamic balance (with the model segmented into seven sections to improve accuracy), calculated via the equivalent static wind load (ESWL) method (considering the first three modes), and verified with the complete quadratic combination (CQC) method. Results within the tested range show that mean wind force decreases with increasing turbulence intensity, while the root mean square (RMS) of wind force increases correspondingly; conversely, the RMS of the tower’s wind-induced response decreases as turbulence intensity rises. These findings highlight the need to comprehensively consider mean and fluctuating wind effects and their impact on structural response in the wind-resistant design of steel TV towers.

1 Introduction

Advances in building materials have facilitated the widespread use of lightweight, high-strength components in the construction of high-rise buildings and television (TV) towers (Yang et al., 2016). These structures are typically slender and feature complex geometries with hollow systems, resulting in low inherent damping and high sensitivity to wind-induced vibrations. A seminal example is the Eiffel Tower (1889), one of the earliest high-quality steel structures (Haan, 1998), whose design principles have profoundly influenced modern TV tower design. Concurrent progress in structural design, wind engineering, and construction techniques has enabled a continual increase in building heights, exemplified by the 634-m Tokyo Skytree. Furthermore, the function of TV towers has expanded from solely transmitting signals to multifunctional complexes supporting communication, tourism, and commercial activities. This evolution presents significant aerodynamic challenges.

Due to their height, flexibility, and complex shapes, TV towers are susceptible to wind-induced disasters, as demonstrated by the collapse of a 386-m steel TV mast in the United Kingdom. Consequently, analyzing their wind-induced response remains a critical focus in wind engineering (Célio et al., 2003; Zhou et al., 2010; Ke et al., 2017; Ch et al., 2021). Standard investigative methods include wind tunnel testing, numerical simulation, and field measurements (Tetsuya et al., 1997). For instance, Zhou et al. (2010) analyzed vibration control for the Hefei TV Tower, finding its response to be dominated by wind-induced vibrations. Xie and Gu (2004) compared time-domain analysis methods, noting that while the linear filtering method is computationally efficient, the harmonic synthesis method offers superior accuracy at the cost of greater computational demand. Zhang and Aiqun (2001) reported that code-based calculations can be more conservative than time-history analysis for communication towers. Wind tunnel studies often employ force balance or surface pressure tests. Liang et al. (1997) used a rocking model to investigate vortex-induced vibrations, while Zhang et al. (2006) applied a lightweight model to validate a building block theory for the Nanjing TV Tower. Kitagawa et al. (1997) addressed limitations of quasi-steady theory with the HAPB method, and Chen et al. (2021a) studied a conical model using forced vibration tests. Although field measurements provide valuable data, their high cost renders them relatively scarce; examples include Chen et al.'s work on steel frame towers (Chen et al., 2021b) and long-term GPS monitoring of the Stuttgart TV tower (Chen Zeng et al., 2021). Computational Fluid Dynamics (CFD) is widely used for its parametric flexibility. For example, Yi et al. (2013) found that Eurocode can underestimate wind responses in certain cases, and Breuer et al. (2008) validated Large Eddy Simulation (LES) techniques for TV tower analysis against wind tunnel data. While these studies effectively characterize aerodynamic properties, the influence of incoming flow characteristics on wind load and response has received less attention.

Some research has begun to address this gap. Belloli et al. (2014) investigated turbulence effects on lattice towers using spires and roughness elements. Carril et al. (2003) analyzed the 610-m Guangzhou New TV Tower using a sectioned model with a high-frequency force balance to represent different turbulence intensities. Xia and Peng (2022) studied a tower on a mountainous site, emphasizing three-dimensional stability. However, these studies are primarily project-specific, and systematic research on how wind field characteristics affect TV tower performance remains limited. To address this, our study examines the influence of turbulent wind fields on the wind resistance of a 240-m TV tower. We generated distinct turbulent conditions in a wind tunnel using spires, grids, and roughness elements to simulate a boundary layer wind profile varying with height. A high-frequency base balance measured the forces on the tower model. Based on these wind loads, we calculated the wind-induced response using the Complete Quadratic Combination (CQC) method. The results summarize the effect of turbulence on the tower’s performance, providing a valuable reference for the wind-resistant design of TV towers.

2 Wind tunnel test

2.1 Introduction to the tower and the model

This study utilizes an existing TV tower as the engineering background. The tower is 240 m high, with a 71.3-m antenna atop the structure. The TV tower features a complex external structure, with its main facade comprising a steel mesh system. The tower serves not only communication functions but also accommodates sightseeing, tourism, and catering facilities, making it an important local landmark. Consequently, the design requirements for its wind-induced response are stringent a 1:200 scale model was developed to simulate the actual TV tower, and 3D printing technology was employed to fabricate a lightweight, high-strength model, as shown in Figure 1.

2.2 Introduction to the wind tunnel tests

TV towers are situated in various terrain conditions, leading to their exposure to diverse wind parameters. To investigate the effects of different wind parameters on the wind load and wind-induced response of TV towers, this study established different turbulent flow fields in wind tunnel tests to examine the influence laws of these parameters. The wind field tests were conducted in the XNJD-3 and XNJD-1 wind tunnels at Southwest Jiaotong University, as shown in Figure 2. The XNJD-3 wind tunnel laboratory is one of the world’s largest civil boundary layer wind tunnels, with a test section size of 22.5 m (width) × 4.5 m (height) × 36 m (length) and a wind speed range of 1.0–16.5 m/s. The XNJD-1 wind tunnel is a tandem single-return type, with a test section size of 2.4 m × 2.0 m × 16.0 m and a wind speed range of 1.0–45.0 m/s.

Figure 2. Wind tunnel laboratory. (a) XNJD-3. (b) XNJD-1.

To simulate varied turbulent wind fields, grids and spires with different ventilation rates were employed in the XNJD-1 wind tunnel, while spires and roughness elements were employed in the XNJD-3 wind tunnel. The wind field measurements were conducted using a TFI Cobra three-dimensional pulsating anemometer (Cobra Probe) manufactured in Australia. Each TFI anemometer is equipped with four probes, enabling accurate measurement of three-dimensional wind speed and static pressure. The TFI anemometer has a maximum measurement frequency of 2 kHz and can measure wind direction angles within a range of ±45°, as shown in Figure 3. To investigate the impact of turbulence on the wind load of the television tower, this study aimed to establish as many different turbulent wind fields as possible. By configuring different grids and spires, five distinct wind fields were generated in the laboratory, as shown in Figure 4. To prevent the model from interfering with the turbulence field measurements, the wind field data were collected prior to model installation. As a segmented model was used in this study and the height of each segment was relatively low, the variation of the wind field along the height within each segment was neglected. The characteristics of the wind fields are summarized in Table 1. Turbulence intensity is a key parameter for characterizing turbulence and has a significant influence on the buffeting and vortex-induced vibrations of the tower. Table 2 shows the natural frequencies of the first vibration mode of the TV tower prototype. Wind speed fluctuations can be characterized by turbulence intensity, which is defined as the ratio of the root mean square (RMS) of the fluctuating wind component to the mean wind speed. The turbulence intensity can be calculated according to Equations 13:

Iα=σαU¯α=u,v,w(1)

Where Iα is the turbulence intensity in three directions, the subscript α denotes u,v and w, respectively, σα are the RMS values of wind speed fluctuations, and U¯ is the constant mean wind speed.

The wind spectrum plays a central role in wind field simulation. This Figure 5 shows the comparison between the wind spectrum simulated in several laboratories and the recommended value (von Kármán spectrum) of the specification. The results show that the wind spectrum and the recommended value of the specification are in good agreement. von Kármán spectrum is as follows:

Where Lu, Lv, Lw are the integral length scales of the downwind, crosswind, and vertical turbulence, respectively; σu, σv, σw are the standard deviations of the downwind, crosswind, and vertical turbulence components, respectively;

2.3 Force measurement in wind tunnel

To accurately measure the wind load and wind-induced response of the TV tower, a segmented model was employed for force measurement tests. To perform synchronous force measurements on different sections, two Nano17 multi-axis force sensors from ATI Industrial Automation (United States) were selected. The balance has a diameter of 17 mm and a thickness of 15 mm. This sensor delivers high-precision, stable data and offers a sampling frequency range of 10 Hz–7,200 Hz. As the sensor cannot be directly connected to the model and support rods, a custom connecting plate was fabricated. The sensor and connecting plate are shown in Figure 6. The complete sensor system includes the sensors, signal converters, and a data acquisition unit. Using a dynamic balance for force measurement requires the model to be lightweight and high-strength, as described in previous article (Zhou et al., 2010). To meet these requirements, the model was fabricated using 3D printing technology.

Figure 6. High frequency dynamic balance and connecting plate. (a) High frequency dynamic balance. (b) Connecting plate.

The force tests were conducted in the wind tunnel laboratories of Southwest Jiaotong University (XNJD-1 and XNJD-3), as shown in Figure 7. A sampling frequency of 1,000 Hz was used, with a sampling duration of 60 s, which is several orders of magnitude higher than the natural frequency of the actual structure. In both wind tunnels, the models were mounted on a rotating turntable to vary the wind incidence angle. The experimental model depicting the coordinate system and wind direction is shown in Figure 8. The Reynolds number effect (4.62 × 104 < Re < 7.94 × 104) was considered negligible in this experiment. This is justified firstly by the sharp-edged profile of the model, which minimizes Reynolds number sensitivity, and secondly by the high turbulence conditions, which further reduce Reynolds number effects.

2.4 Wind tunnel test results

2.4.1 Test data processing

Force is measured using a high frequency dynamic balance to obtain its historical values. In order to facilitate subsequent calculations, the authors usually perform dimensionless processing on the time history of the force. Commonly used processing methods such as Equations 4, 5:

μFX,Ytp=2FX,Yptp/ρUp2HpDp,(4)
μMZtp=2MZptp/ρUp2HpDp2,(5)

where FX,Yp and MZptp are the historical values of the force in each direction obtained from the test, and U, V, and W denote the longitudinal, lateral, and vertical directions, respectively. The parameter p refers to the model number, such as 1, 2, 3, etc. Hp and Dp refer to the characteristic dimensions of the model.

In this study, a uniform test wind speed was used for all the segment moduli, but in fact the wind speed varies with the height in the actual building.

In this paper, borrowing the research of Ke et al. (2017) and others, a reduced time scale λt (λt=λL/λV: the ratio of length scale to velocity scale) is introduced into the calculation. At the same time, the concept of peak factor g is introduced. The wind force acting on the TV tower can be calculated according to Equations 6, 7:

FXjYjt=12ρUWj2HjDμFXFYt,(6)
MZjt=12ρUZj2HjDμMZt,(7)

where FXjYjtMZjt is the wind time history of each direction obtained above. H and μ are the gradient height and exponent of the mean wind speed profile, respectively.

2.4.2 Wind force and wind force coefficient

Following data processing, the force coefficients for each test condition were obtained. To facilitate a clearer comparison, this study presents only the mean force coefficient values for each condition, with the wind direction angle also considered. The calculated force coefficients for Sections 1, 4, and 7 under various conditions are presented in Figure 9. The results clearly demonstrate that turbulence intensity significantly affects the force coefficient, with higher turbulence levels resulting in reduced force coefficients.

Figure 9
Nine line graphs show the effects of wind direction on three forces, µFₓ, µFᵧ, and µFz, across different conditions. Each row of graphs represents different turbulence intensity levels: (a) Iₗ = 14.2 to 18.2, (b) Iₗ = 13.1 to 15.9, and (c) Iₗ = 10.8 to 13.2. The x-axis is wind direction from -90 to 90 degrees for all graphs. Each graph displays lines representing different turbulence intensities, showing variations in force components as the wind direction changes.

Figure 9. Variations of mean, maximum, and minimum wind force coefficients with wind direction for the different sections. (a) Section 1. (b) Section 4. (c) Section 7.

Figure 9 presents the mean wind force coefficients, showing that these coefficients decrease with increasing turbulence intensity. To further investigate the influence of turbulent flow on wind forces, the root mean square (RMS) values of wind forces were calculated for each segment. The RMS values under each turbulent flow condition were analyzed, with the results for the T1 flow field (corresponding to a wind speed of 32.2 m/s with a 100-year return period) shown in Figure 10. The figure demonstrates that the RMS values vary with wind direction. At a wind direction angle of 0°, the absolute mean wind force in the Mz direction reaches its maximum value. As the wind direction angle increases to −90°, the mean wind force gradually approaches zero. Similarly, at a wind direction angle of −90°, the absolute mean wind force in the X-direction is approximately zero, while at 0°, the mean wind force in the X-direction increases significantly. Notably, the wind force results are not perfectly symmetrical about different wind angles, which can be attributed to the combined effects of turbulence and the structural geometry.

Figure 10
Six line graphs depict relationships between different forces and moments along a structure’s height. The top row (labeled a) shows graphs of force \( F_x \), force \( F_y \), and moment \( M_z \) with height. The bottom row (labeled b) shows the same variables, \( F_x \), \( F_y \), and \( M_z \), with varying scales. Each graph includes a red line indicating a reference or baseline.

Figure 10. Distributions of mean, maximum, and minimum wind forces along the tower (T1). (a) 0 degree wind direction. (b) −90-degree wind direction.

To compare the wind force RMS values across different turbulence intensities, the RMS values were analyzed as a function of height, as shown in Figure 11. The analysis reveals that the wind force RMS values vary significantly with height, consequently influencing the mean wind force coefficients. This finding, combined with previous results, demonstrates that while increased turbulence intensity reduces the mean wind force, it simultaneously increases the RMS value of the wind force.

Figure 11
Two line graphs show relationships between height and force parameters labeled from \(L_1\) to \(L_5\). The left graph plots \(F_x\) (kN) against height (meters), showing a decline, reaching a minimum around 150 meters, and then rising. The right graph plots \(M_z\) (kN.m) with a similar trend. Both graphs use the same legend indicating five lines, differentiated by colors, representing different variables.

3 Wind-induced responses

For high-rise structures like TV towers, designers must account for both the mean wind-induced structural response and the extreme responses arising from turbulent fluctuations. Accurate calculation of the root mean square (RMS) value of the dynamic response is particularly important for comfort criteria, since the upper floors of TV towers typically accommodate observation decks and restaurants. Given the complex geometry of many towers, the response calculation often requires appropriate simplifications. For tall buildings, especially slender structures, wind-induced response analysis typically treats these structures as linear systems with lumped mass distributions. A common multi-degree-of-freedom mechanical model for such structures is shown in Figure 12. Finite element simulations are generally employed to extract the dynamic characteristics of these structural systems.

The ends are labeled \(M_1, \text{MMI}_1\) and \(M_n, \text{MMI}_n\). The base shows a coordinate system with axes \(X\), \(Y\), and \(Z\) originating from point \(O\).

3.1 CQC method

The equation of motion can be expressed as Equation 8:

Mδ¨+Cδ˙+Kδ=RFt(8)

where M, C and, K are the mass matrix, damping matrix, and stiffness matrix, respectively, and δ, δ˙, δ¨ are the vectors of displacement, velocity, and acceleration, respectively. The random wind load Ft can be determined according to Equation 9:

Ft=FX1t,FY1t,MZ1t,···,FXmft,FYmft,MZmftT,(9)

By evaluating the response power spectral density matrix using the CQC method, the following Equation 10 is obtained:

Sδδw=HTRSFFwRTHT,(10)

where H is the matrix of transfer functions, is the matrix of mode shapes, and SFFw is the force spectrum matrix. The CQC method involves all modal coupling terms that consider the mutual influence effects between the mode shapes. The RMS response of displacement and acceleration can be derived by integrating the power spectrum as shown in Equations 11, 12:

σδz=0Sδδwdw,(11)
σδ¨z=0w4Sδδwdw,(12)

For buildings with non-coupled vibration modes, only one term was included in the generalized force, and the other two terms were zero.

In order to calculate the various data of the model, a finite element model was established in ANSYS to calculate the dynamic characteristics of the model, the vibration modes of the high-rise structure, and only one-dimensional vibration mode forms were considered in each principal axis direction. The specific parameters and steps in the finite element are as follows:

1. Apply forces in the same direction to each particle on the first node layer of the three-dimensional finite element model, and make the sum of all forces 1. Torque is applied at two points symmetrical about the center (1/L).

2. Determine the K-direction displacement of each node in the j-th node layer to obtain the different flexibility coefficients, and then form a flexibility matrix with the flexibility coefficients.

3. Invert the flexibility matrix to obtain the stiffness matrix.

3.2 Results of wind-induced responses and equivalent static wind loads

The wind load calculation method in this paper follows the equivalent static wind load (ESWL) procedure developed by Ke et al. (2017). Figures 13, 14 present the RMS values of the wind-induced response and internal forces of the TV tower structure under various test conditions. The results demonstrate that the RMS response of the TV tower increases with rising turbulence intensity. Figure 14 demonstrates the underlying mechanism—the RMS structural response is directly proportional to the RMS internal force within the structure.

Figure 13
Three line graphs display the relationship between height in meters and different standard deviations: σ\_UX, σ\_UY, and σ\_RZ. Each graph includes five series, labeled L\_1 to L\_5, represented by distinct markers: square, circle, triangle, inverted triangle, and diamond. The x-axis for the first graph ranges from 0 to 0.5, for the second from 0 to 0.4, and for the third from 0 to 0.0002. All graphs show similar upward trends as height increases.

Figure 14
Five line graphs depicting structural displacements with respect to height, labeled by various parameters (σFX, σFY, σMZ, σMX, σMY) in kilonewtons or kilonewton meters. Each graph shows multiple lines representing different cases (Iu1 to Iu5) with height on the y-axis ranging from 0 to 250 meters. A legend within each graph identifies the line styles corresponding to each case.

Figure 14. RMS internal force of structure (90° wind direction, 100 years return period).

This paper adopts two methods, CQC and ESWL, which are currently widely used. Therefore, the interaction between the two methods is used for verification. From Figure 15, it can be seen that the results of the two methods coincide well, indicating that the calculation results of this paper are reliable.

Figure 15
Three side-by-side graphs display structural analysis results. Each graph plots height in meters against different deformation metrics: σ_UX, σ_UY, and σ_RZ on the x-axes. Purple circles represent ESWL results, while black squares represent CQC results. All graphs show similar curvature trends, with data points up to 250 meters in height.

4 Conclusion

TV towers typically serve broadcasting functions and often include facilities such as observation decks and restaurants at elevated levels, including the tower top. Owing to their slender structure, TV towers are highly susceptible to wind effects, and excessive responses may compromise tourist comfort. Therefore, the research on the wind response of the TV tower in turbulent flow has strong practical value. Based on a comprehensive series of wind tunnel tests and analytical calculations, the following conclusions are drawn:

1. Wind tunnel test results, obtained using a high-frequency dynamic balance, demonstrate that the wind direction angle exerts a periodic influence on wind forces. However, this periodicity is not absolute due to the effects of structural shape. The downwind force reaches its maximum at a wind direction angle of 0°. Additionally, the results indicate that wind forces measured in a closed test section exceed those measured in an open section.

2. The results obtained from the Complete Quadratic Combination (CQC) and Equivalent Static Wind Load (ESWL) methods show mutual verification, confirming the high reliability of the findings presented in this study. The experimental results further demonstrate that increased turbulence intensity reduces the mean wind force while simultaneously increasing the root mean square (RMS) value of wind forces.

3. Analytical results indicate that higher turbulence levels increase the RMS value of the wind-induced response of TV towers. This finding underscores the importance of considering turbulence intensity effects on structural response in the design of high-rise buildings located in high-turbulence regions.

4. Due to the use of passive wind field simulation technology in this article, precise control of turbulence intensity and other parameters cannot be achieved, and the underlying mechanisms and mathematical relationships cannot be studied. In the future, it is hoped that research can be conducted in active control wind tunnels to clarify the mechanisms and mathematical relationships.
