新型装配式减震剪力墙的研究
|
摘要
对装配式剪力墙结构的研究现状及相关规范、规程进行分析,提出了一种在墙肢开竖缝,并设置阻尼器的新型装配式减震剪力墙结构。通过数值模拟分析和低周反复荷载试验表明,该结构与普通剪力墙相比,承载力及刚度有所减小,但延性明显提高,改善了剪力墙的抗震性能,并针对该结构提出设计建议。
This paper briefly describes the research status of assembly shear wall structure,the related standard and rules.A new type of assembly damping shear wall with vertical seams in the wall and damper embedded in it is proposed. The numerical simulation analysis and low reversed cyclic loading tests show that the bearing capacity and rigidity are reduced compared with ordinary shear wall. But the ductility is increased significantly. Therefore,the anti-seismic performance of the shear wall is improved,and suggestions are put forward on anti-seismic design.
