摘要
应用大型有限元软件ANSYS开展了四层钢框架结构的有限元分析,得到了构件的内力和整体变形,通过验算框架的承载力和刚度均满足要求;随后开展了四层钢框架的模态分析,得到了钢框架前3阶自振频率和相应振型,为进一步开展钢框架的动力分析奠定基础。
Finite element analysis is carried out for four-story steel frame structure adopting ANSYS software,internal force of component and overall deformation are got,Through the calculation of the bearing capacity and stiffness of the frame meets the requirement.Subsequently four story steel frame modal analysis is performed,the first three natural frequencies and the corresponding vibration modes of steel frame are obtained.These are the basis for further dynamic analysis of steel frames.
