摘要
本文研究了竖向不规则结构Pushover分析中的侧向力分布问题,建立了3个竖向不规则平面框架结构模型,提出了振型组合自适应分布的实现方法。利用5种不同的侧向力分布模式对3个结构模型进行了Pushover分析,并与弹塑性时程分析进行了对比。结果表明,振型组合自适应分布与时程分析结果最为接近,对复杂的竖向不规则结构,可以利用该分布模式进行Pushover分析。
The lateral force distribution pattern of vertical irregular structure in Pushover analysis is studied.3 vertical irregular plane frame structure models are established.A realization method of the model combination adaptive distribution pattern is put forward.5 different kinds of lateral force distribution patterns are used on the Pushover analysis of the 3 models,which are compared with those on the nonlinear time history analysis.It is shown that the model combination adaptive distribution pattern is in accordance with the nonlinear time history analysis and can be used in the Pushover analysis for complicated vertical irregular structure.
