摘　　要：前期已对该框架核心筒结构进行了弹塑性动力时程分析,得到的结构基底剪力-顶点位移的平均结果作为本文分析研究的标准之一。本文中,进一步研究了该结构在不同加载模式下和是否考虑P-Δ效应对Pushover分析结果的影响。结果表明,推荐采用实时加载分布模式对该高层框筒结构进行静力弹塑性分析。The elastic-plastic dynamic time-history analysis of the framed-tube structure is carried out in the early stage, and the average results of the shear-apex displacement of the structural base are taken as one of the anal- ysis and research standards in this paper. The effect of the structure in different loading modes and whether to consid- er the effect of P-△ on Pushover analysis results were further studied. The results show that the real-time loading and distribution model is used to analyze the elasto-elasto-plasticity of this high-rise framed-tube structure.
