摘要
采用PERFORM-3D软件及纤维剪力墙单元,通过对一14层筒中筒结构试验模型进行弹塑性时程分析,并与试验结果对比,验证了软件模型的合理性。通过结构在不同烈度情况下的变形分析,具体研究了该结构的层间位移角分布,并参考美国性能规范ASCE41—06,对结构在弹塑性阶段的性能进行评估。得出在高烈度地震动下结构底部剪力墙出现较大塑性变形,以耗散大部分能量,同时给出相应的设计建议,为同类高层结构弹塑性分析提供参考。
Basing on the PERFORM-3 D software and macroscopic shear wall unit, the results of elastic-plastic time history analysis in a 14-story tube-in-tube structure with the experiment results are compared, which verifies the rationality of the software model. The seismic response is calculated under different earthquake intensities, the inter-story drift distribution is discussed in details. To evaluate the structure behavior performance in elastic-plastic phase, america performance standard ASCE41-06 is used. Calculation results show that the base shear wall have a large plastic deformation to dissipate energy during high-intensity earthquake, meanwhile raising a design recom- mendation, which provides a reference of elastic-plastic analysis in similar high-rise structure.
