About this Research Topic
Structural metal based frames are widely used in multi-story buildings and complex structures of the mega-cities while their connections play a vital role. After the 1994 Northridge and 1995 Kobe earthquakes, the need for better understanding of connections’ performance under accidental and extreme (seismic) loading was highlighted. FEMA research program and the SAC Joint Venture, the National Institute of Standards and Technology (NIST) and the AISC completed numerous studies investigating the performance of connections. Today, researchers and industry are on a constant demand for innovative, resilient, flexible and adaptable ‘smart’ connections used in slender frames, (super-tall) towers and skyscrapers. Their complexity should be diminished, and their performance should be well understood and predicted.
This Research Topic welcomes experimental, computational and analytical research on metal based (carbon/ stainless/ high strength/ cold-formed steels, aluminum and its alloys, titanium, hybrid, etc.) connections subjected to (quasi) static and dynamic loads simulating normal as well as extreme load conditions such as earthquakes, progressive collapse scenarios, high-wind actions (tornados) as well as uncovered coupled loading scenarios. This research theme is dedicated to present advances in connections and their design aspects, in particular following the advent of recent technologies, and will attempt to seek elegant yet unexplored solutions.
The editors would like to encourage studies that outline a broad range of developments in the primary disciplines of engineering structures as we know them today. Articles discussing methodologies and reviews of the current state of knowledge, and opportunities for future research are welcome in particular. Manuscripts regarding original research proposals and research ideas are highly appreciated. Papers containing summaries and surveys on research cooperation and future projects (as those founded by national governments or other organizations) are likewise appreciated, as they provide state-of-the-art knowledge for a broad field of users. Further, this Research Topic intends to provide a forum for a productive exchange of ideas and interaction amongst industry and academia.
Suitable manuscript topics include, but are not limited to:
• Retrofitted/strengthened connections;
• RBS and RWS connections;
• Pin-fuse connections;
• Replaceable components;
• Demountable connections;
• Self-centered connections;
• Code-deficient connections;
• Aged (corroded and fatigued) connections;
• Structural optimization in connections;
