About this Research Topic
Construction in civil engineering by its very nature is a major contributor to the use of natural resources. With growing concerns over the environmental issues related to the exploitation and consumption of such resources, there is a great pressure on the construction industry to reduce their negative environmental impact. Catering for these concerns, sustainable construction has been encouraged around the world to reduce construction materials, and the use of high strength steel and concrete in composite members serves this purpose well. Instability and poor ductility are the key problems affecting the use of high strength steel and concrete, respectively. However, when they are used in composite structural members, such as the concrete filled steel tubes or the concrete encased columns, the ductility and instability can be improved.
High strength steel and concrete materials have been found to be attractive alternatives to conventional materials for high-rise construction. The use of high strength materials is ideal for columns in high rise buildings. This is because the higher the material strength, the smaller the member size required to resist the same design load. This will free up more usable floor space and require less construction materials and construction work. Although significant progress has been made in the effective production of high strength steel and concrete materials, there are still many challenges hindering their successful application in various types of civil infrastructures. The main objective of this Research Topic is to collect a series of quality articles that present a scientifically and technically rigorous approach to the area of innovation in high strength steel and concrete materials for composite elements, understanding their physical/mechanical properties, and facilitating their engineering applications.
The research results reported in this Research Topic address all the aspects of theoretical and experimental studies on composite structural members utilizing high strength steel and concrete materials, in terms of:
• Material properties,
• Buckling and stability,
• Dynamics and vibrations,
• Fire performance,
• Connection behavior,
• Fabrication and maintenance,
• Strengthening and repairing,
• Combining with other high-performance materials,
• Assessment of potential environmental savings from using high-strength materials to reduce resource consumption.
This Research Topic aims to bridge the gap between the theoretical developments and practical applications for the use of these materials. As such, contributions from practicing engineers are especially welcome.
