开洞的钢板和型钢支撑-混凝土组合剪力墙抗震性能试验研究
|
摘要
根据实际工程,对长宽比为3.08的筒体的短边墙体进行模型试验。试验模型为钢管边框,内部设置型钢支撑、局部开洞的钢板-混凝土组合剪力墙。采用低周反复模式加载,分析试件极限承载力、构件延性和破坏特征。通过试验分析,钢板-混凝土剪力墙的钢管边框、钢板、钢框架能很好地协同工作,可较明显提高组合剪力墙的承载力和延性。试验结果同时也指出,开洞组合剪力墙在设计中应采取构造加强措施,有利于进一步提高结构的承载力和延性。
Based on the actual engineering design,the short walls in core tube were tested.The walls have steel pipe frame outside,steel bracing and holed steel plate,with length-width ratio 3.08.Under the low reversed cyclic load,the ultimate bearing capacity,ductility,main failure modes were obtained.Through the experiment,the holed steel plate and the steel bracing-concrete composite wall can work together,and improve bearing capacity and ductility.The results also show that the holed steel plate and the steel bracing-concrete composite wall should be strengthened to further improve the bearing capacity and ductility.
