框架填充墙结构的静动力学特性
|
摘要
利用MIDAS/Gen有限元分析软件,对框架填充墙结构的静动力学特性进行研究。由模态分析得结构基频为0.9252 Hz,高阶振型的模态参与系数远小于低阶模态参与系数,即低阶振型对于振动起控制作用;以反应谱的两个频率段为根据来选取时程波,时程分析结果大于反应谱分析结果的80%。通过对本模型的反应谱分析和时程分析得到了关于框架填充墙结构动力特性,并指出了结构薄弱部位,对同类结构的设计与分析有指导意义。
In this paper, static and dynamic characteristics of infilled wall structure were studied using the finite element analysis software MIDAS/Gen. The fundamental frequency of 0.9252 Hz was obtained by modal analysis. High-order modal participation factor was far less than the low-order modal participation factor, i.e., low-order modeplays a dominant role in the vibration. Time-history curve was selected based on two frequency bandsof the response spectra, and time-history analysis results were more than 80% of the response spectrum analysis results. The static and dynamic characteristicsof infilled wall structurewere obtained through response spectrum analysis and time- history analysis of this model, and the weak part of the structure was indicated, which may provide reference for the design and analysis of similar structures.
