大底盘等高双塔结构的抗震性能

Seismic behavior of equal altitude double-tower building with a large base

对大底盘等高双塔的抗震性能进行分析,建立两个模型,分别进行双向反应谱分析、线性时程分析及pushover分析,由分析所得层间位移角及塑性铰的发展变化对其抗震性进行评估。结果表明:大底盘双塔连体结构比大底盘双塔结构整体性好。

This text mainly analyzed the seismic behavior of equal altitude double-tower building with a large base, established two different types of model and performed a series of analysis, including bidirectional re- sponse spectrum analysis, linear time history analysis, and Pushover analysis. Evaluation was made on the structures＇ seismic performance from plastic hinge and inter-story displacement angle. The result showed that double-tower building conjoined structure has good integrity.
