用ANSYS模拟任意层数框架结构的地震反应分析
|
摘要
运用有限元软件 ANSYS 对一特定的7层框架结构在水平地震作用下的受力进行了模拟计算,着重分析了实体模型的时程分析,得到了框架结构的动力特性和模拟地震反应,与实验室中1m×1m 地震模拟振动台上的试验结果近似,可见用 ANSYS 软件可以模拟任意层数框架结构的地震反应。同时,介绍了框架结构运用ANSYS 进行结构有限元分析的基本过程。
This paper presents simulation calculating results of the force in specific 7 floor frame structure building imposed on horizontal earthquake force,using finite element (ANSYS) program.Time analysis of solid model is mainly analysed.The dynamic characteristics and simulate seismic response are found to be close to that on the 1m×1m seismic simulate shake table in the lab.It shows that using ANSYS to simulate the seismic response of arbitrary frame structure is valid and usable.Meanwhile,the paper makes an presentation of the basic process that structure analysis of frame structure building is worked out by finite element program(ANSYS).
