柔性连接填充墙框架结构抗震性能试验
Experiment on Seismic Behavior of Flexible Connection Masonry Infilled Frame Structure
【摘要】 通过5榀空心砌块砌体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、全墙填充和半墙填充框架结构的破坏机理和抗震性能,进行了结构滞回特性、承载力、位移延性、刚度退化、强度衰减、耗能能力及变形性能指标分析.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,说明柔性连接方案减小了墙-框相互作用,有效改善了填充墙框架结构的抗震性能.
【Abstract】 In order to study the failure mechanism and seismic behavior of hollow block masonry infilled framework with flexible and rigid connection between infilled wall and frame,or with all-height and half-height infilled wall,the low-cyclic reversed loading test of 5 RC infilled frames was conducted. Meanwhile,an analysis was made of hysteresis character, bearing capacity, displacement ductility, stiffness degradation, strength retrogression,energy dissipation and deformation index of structure. The results show that flexible connection specimens have lower bearing capacity than rigid connection specimens,but the other performance indexes are better. As a result,flexible connection scheme can reduce interaction between infilled wall and frame,thus improve the seismic performance of infilled frame structure.
