| 摘 要： | 采用钢结构加层后，结构的整体质量、刚度、周期、阻尼比等都发生了较大的变化，应进行结构的整体分析。结合具体的工程实例，采用有限元软件ANSYS，对某4层钢筋混凝土框架结构办公楼顶部加2层钢框架结构进行抗震性能的时程分析，计算结果可为加层结构的抗震设计提供参考。

| Abstract: | Significant differences occur in the mass, stiffness, period and damp ratio after adding steel storeys on the top of the original building. It is necessary to analyze the integral structure due to the unreliability of calculating the adding storeys independently. In this paper, an FEA software package ANSYS was employed to one four-storey reinforced concrete office building with two-storey steel frame on the top to do the time-history analysis on the seismic properties. Some suggestions are proposed on seismic design of adding storeys. |
