本文利用MIDAS Civil通用有限元软件,模拟了某1-59m异形钢混结合梁,建立了整体有限元分析模型。对该结构进行了5种工况下的强度验算、位移及支座反力验算、剪力键的计算以及疲劳强度验算。各项计算指标均满足相关规范的规定,结构具有一定的强度可靠性。
In this paper, a finite element analysis model of a finite element is established by using the finite element software MIDAS Civil to simulate a 1-59m deformed steel-concrete composite beam. The structure under five conditions of strength checking, displacement and bearing check, shear stress calculation and fatigue strength checking. The calculation of indicators to meet the relevant provisions of the norms, the structure has a certain degree of strength and reliability.
