摘要
进行动力弹塑性分析时,采用不同的阻尼模型会对分析结果产生较大的影响。本文采用一个框架剪力墙结构算例进行动力弹塑性分析,阻尼模型选取了瑞利阻尼、质量阻尼和振型阻尼三种常见的阻尼模型,对层间位移角、节点位移时程曲线、能量图、构件损伤等分析结果进行对比,并据此对动力弹塑性分析时阻尼模型选取给出建议。
Using different damping model in Elasto-plastic dynamic analysis will produce big influence on analysis results.This article conducts elasto-plastic dynamic analysis for a frame-shear wall structure,where uses three kinds of damping model:rayleigh damping,mass damping and modal damping,and compares the results of story drift,nodal displacement time history curve,energy diagram and member damage and so on.Based on the comparisons,this article gives a suggestion for the damping model adoption in elasto-plastic dynamic analysis.
