钢-混凝土组合剪力墙抗震研究与发展

剪力墙是高层建筑抗震的主要抗侧力体系,随着大型复杂高层建筑的快速发展,对剪力墙抗震性能的要求也越来越高,钢-混凝土组合剪力墙就是一种抗震性能好的剪力墙。国内外在钢-混凝土组合剪力墙抗震研究方面,从抗震性能到设计方法和工程应用都取得了较快的发展。本文介绍了国内外有关钢-混凝土组合剪力墙抗震研究的部分成果,同时介绍了笔者提出的钢-混凝土多重组合剪力墙及其抗震研究情况,包括工程应用情况。已有研究表明:钢-混凝土组合剪力墙特别是钢-混凝土多重组合剪力墙,具有良好的抗震屈服机制和多道抗震防线,抗震耗能能力强,工程应用价值较大。

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

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.
