摘要
结合实际工程中针对带有长悬臂雨篷的超大跨度门式钢架结构进行有限元分析,基于SAP2000有限元软件的特点和钢架结构的基本特征,对结构影响较大的14轴和A轴进行了内力效应分析,观察长悬臂雨篷对超大跨度门式钢架结构的影响程度,并给出在不同荷载工况作用下14轴和A轴柱中节点应力的最大值,为工程结构设计提供依据。
finite element analysis of surpass large span portal steel frame with long cantilever awning with the actual project is conducted. This paper based on the characteristics of SAP2000 finite element software and steel structure, analyzed force effect on the 14-axis and A-axis of Greater impact on the structure; researched effect level of the surpass large span portal steel frame caused by long cantilever awning; and gave out the maximum stress value of 14-axis and A-axis column node at different load conditions, provided a theoretical basis for engineering structure design.
