摘要
根据钢框架结构的受力特点,运用有限元的思想,提出将钢框架结构离散为梁单元,借助于有限元模态分析方法进行钢框架的动力特性分析,求解其频率和位移。此法为准确地分析钢框架梁的动力特性提供了简便的方法。
Current standards of steel structure design do not involve steel dynamic properties analysis.The complicity of steel frame structure makes its dynamic analysis a difficulty.The idea of dispersing the steel frame into beam units by finite element method is proposed in this paper.The natural frequencies and the displacements are also calculated by finite element modal analysis,which provides a precise prediction for dynamic reaction analysis of steel frame.
