某平面框架在水平荷载作用下的有限元分析

Finite Element Analysis on the Plane Frame under Horizontal Load

利用有限元分析软件ANSYS对某平面框架进行水平荷载——风荷载、地震荷载作用下内力计算,并同手工计算方法进行了比较。结果表明,两种计算方法结果十分接近,并且利用有限元计算结果速度快,可以直接生成内力、变形图形,如果计算的结构类型更为复杂,有限元分析的优点更为突出。

The plane frame is calculated under horizontal load-wind and earthquake by using ANSYS finite element analysis software. And the calculating result of FEM analysis is compared with the manual calculating result. The results show that the calculation is similar, the calculation speed is quick, and the graph of internal force and deformation can get. If the calculated structure type is more complex, the virtue of finite element analysis is more extrude.
