摘要
为验证大跨度无竖杆钢桁梁节点板设计的可靠性,以某高速铁路108 m双线下承式无竖杆简支钢桁梁某一节点及其横梁为研究对象,采用有限元软件midasFEA建立有限元模型,对其应力及横向变形进行分析,得出本节点满足受力及横向变形要求,为之后的设计积累经验。
To verify the reliability of the gusset plate design of large-span steel truss girder without vertical member, this paper, taking a node and its floor beam of the 108 m double-track through-type simply-supported steel truss girder without vertical member on a high-speed railway as the research object, establishes the finite element model using the finite element software named midasFEA, and analyzes its stress and horizontal deformation. Finally the paper draws a conclusion that this node can meet the requirements on stress and lateral deformation. This analysis is also useful to gather experience for the design in future.
