静力弹塑性分析方法在高层结构中的应用
|
摘要
Pushover分析方法是一种逐渐得到广泛研究与应用的评估结构抗震性能的简化方法,已经被我国现行GB50111-2010《建筑结构抗震设计规范》采纳,可直接用于对多层结构进行评估计算。为使静力弹塑性分析方法进一步推广到高层结构,通过对某高层算例采用PKPM2010版PUSH&EPDA进行计算,将利用动力时程分析方法和静力弹塑性分析方法所得到的两种结果进行比较,并提出优化建议,为静力弹塑性分析方法的进一步推广提供参考。
Pushover analysis is a simplified method for structure seismic evaluation,which is extensively studied and applied gradually.The method has been adopted by the current code of seismic design of buildings.The pushover analysis is also added in PKPM2010.Comparison of results between nonlinear time history analysis and pushover analysis is carried out,and based on the calculating results,some regulations are proposed to ensure the safety of the structure.
