| 摘 要： | 采用ANSYS有限元软件分析了一竖向不规则的型钢混凝土框架核心筒结构的动力特性和多遇地震下的位移反应,通过Pushover分析考察了结构的整体抗震性能和薄弱部位,分析结果表明结构竖向收进处由于刚度的突变成为整个结构的薄弱环节。

| Abstract: | The dynamic property and displacement responses under frequent earthquakes of a SRC frame-tube structure with vertical irregularity are analyzed by finite element program ANSYS.The structural seismic behavior and weak position are discussed through Pushover analysis.The results show that the setback story became the weak position because of the sudden change of stiffness. |
