柔性连接新型砌体填充墙框架结构抗震性能试验研究
|
摘要
通过5榀钢筋混凝土填充墙框架结构低周反复荷载试验,系统研究了填充墙-框架柔性连接和刚性连接、墙端设置芯柱和不设置芯柱结构的破坏机理和抗震性能,对滞回曲线、骨架曲线、位移延性比、累积耗能、强度衰减和刚度退化等抗震性能指标进行了分析。试验结果表明:柔性连接方案对结构承载力的提高低于刚性连接方案,但其他性能指标均优于刚性连接方案。例如,提高了结构初始刚度,且刚度退化现象减缓;提高了结构位移延性比和累积耗能;填充墙破损程度减轻;减小或消除了填充墙对框架柱的附加剪力影响等。同时,填充墙内芯柱的设置有效提高了结构承载力、刚度和整体稳定性。
In order to study failure mechanism and seismic behavior of infilled framework with flexible and rigid connection between infill wall and frame,setting core column and no setting core column in the wall end,the low cyclic load test of 5 RC infilled frames are conducted. The seismic performance including hysteresis curves,skeleton curves,displacement ductility coefficient,cumulative energy dissipation,strength retrogression and stiffness degradation were studied systematically. The experimental results showed that flexible connection specimens had lower bearing capacity than rigid connection specimens,but the other performance indexes were better. For example,flexible connection specimens can increase initial stiffness of the structure and at the same time retard the stiffness degradation phenomenon,improve displacement ductility coefficient and the ability of energy dissipation of the structure,alleviate the damage of the filler wall,reduce or eliminate the effect on the additional shear which the filler wall acts on frame column,etc. In the meanwhile,the setting of core column in the filler wall improves the structure bearing capacity,stiffness and stability as a whole effectively.
