摘要
鉴于连肢剪力墙结构破坏机理及连梁在连肢剪力墙结构中的特殊作用,提出采用耗能减震方法提高罕遇地震作用下剪力墙结构性能的抗震设计思想,并设计出一种实用的新型软钢耗能构件及其代替或附加于连梁上的构造方案,以提高剪力墙结构的抗震性能。动力弹塑性计算结果表明,该新型软钢耗能构件耗能效果良好,罕遇地震作用下剪力墙的抗倒塌性能得以提高。
In order to enhance the performance of shear wall structure under severe earthquake, a new seismic design method, energy dissipating and vibration control technology is brought forward. In this paper, based on previous researches on collapsing mechanism of shear wall structures and design methods of coupling beam, a new adaptive mild steel damper is designed, which enhances the performance of shear wall under severe earthquake through replacing or adding itself on the coupling beam. Results from ABAQUS dynamic elastic-plastic analysis show that this new damper has well energy dissipating performance. The anti-collapsing ability of shear wall under severe earthquake is enhanced.
