中文摘要：
对某立面收进型钢混凝土框架一混凝土核心筒超限高层建筑结构，建立材料应力-应变层次上的弹塑性分析模型．借助有限元软件ABAQUS及其材料子程序二次开发平台，采用显式算法对该结构进行罕遇地震作用下的弹塑性动力时程分析，研究该复杂结构的弹塑性变形和受力特点．结果表明，在罕遇地震作用下结构的弹塑性变形能够满足国家规范限值要求，实现大震不倒的抗震设防目标；但在结构立面收进处、核心筒底部加强部位和非加强部位交界处存在刚度突变而导致变形集中，建议设置过渡层，保证刚度连续、均匀变化．
英文摘要：
A super-tall building with two setbacks in by direct termination of vertical members, structure an irregular one. A detailed Abstract .. generated makes the elevation was introduced. One setback and the other is realized by inclining finite element analysis model of the is structurally columns. This building was developed by using ABAQUS and its user material subroutine program in order to investigate the seismic behavior of this structure. Then the elasto-plastic time history analysis was performed using explicit integration numerical solution method. Results show that the structural system has sufficient seismic capacity and ductility to resist rare earthquake. The plastic deformation capacity of this building can meet the requirement of Chinese code, and seismic performance objective of no collapse under rare earthquake can be reached. However, deformations were found concentrated in members within and adjacent to setback stories, at the bottom strengthening portion of core walls and its upper story where lateral stiffness suddenly changed. It was suggested that transfer stories should be placed above or below these stories to improve the concentration of strain and deformation.
