混凝土空心砌块砌体结构的动力反应分析
|
摘要
通过对一座6层配筋混凝土砌体结构住宅单元进行非线性动力时程分析,研究结构的抗震性能。结构计算模型考虑层间剪切变形,层间刚度采用线弹性模型。地震反应分析结果说明动力分析中所用的结构计算模型、恢复力模型和参数及计算程序是可行的。在不同地震动情况下,结构纵向变形大于横向变形,证明结构的纵向抗震能力比横向低;设置芯柱—构造柱的砌块结构能满足7度抗震要求。结果可为配筋混凝土砌体结构抗震分析和设计提供参考。
An experiment was conducted to study the seismic performance of masonry structure of reinforced concrete hollow block according to the analytical result of a six-story reinforced concrete masonry building model by the method of nonlinear time history analysis.The inter-story shear-deformation in the analysis model was taken into account and the inter-story stiffness was calculated by the linear elastic model.The availabilities of the analysis model,hysteretic model and relevant parameters adopted and the developed computation program were verified.The longitudinal deformation of the structure was more obvious than the lateral deformation under different earthquake waves,which shows that the longitudinal seismic performance is better than the lateral.For seven-story concrete block building with core-and tie-columns,the requirement of the seismic fortification intensity can be met.
