Development and research in seismic performance of steel-concrete composite shear wall

DONG Hongying,JIANG Feng,CAO Wanlin(College of Architecture and Civil Engineering,Beijing University of Technology,Beijing 100124,China)  
Shear walls are the main anti-lateral force system for the seismic design of high-rise buildings.With the development of large-scale complicated high-rise buildings,requirements for seismic performance of shear walls have become more sophisticated.The steel-concrete composite shear wall shows good seismic performance.It has made rapid development at home and abroad through the research of seismic performance in the way of seismic design to the practical engineering application of steel-concrete shear walls.In this paper,part of the achievements related to the composite wall is introduced.In the mean time,the project application and the multiple steel-concrete composite shear wall invented by the author's project group is introduced.Studies have shown that the steel-concrete composite shear wall,especially the multiple steel-concrete composite shear wall,shows effective seismic yielding mechanism,remarkable seismic energy-dissipation capacity and multiple seismic defence lines.It has high value to engineering applications.
