| 摘 要： | 以京沪高速铁路64 m简支下承式钢桁结合梁桥为对象,采用作者曾经提出的空间板梁单元和常规板壳单元、空间梁单元和空间桁单元离散结构,对其在偏载荷载作用下的受力特性进行空间有限元分析,计算主桁、混凝土板和纵、横梁的应力和位移。结果表明:该桥在偏载荷载作用下符合强度刚度要求。

| Abstract: | The mechanics property of a through steel-truss composite beam bridge on Beijing-Shanghai high-speed railway with simple supportion under deflection loads,whose span is 64 m,was studied with finite element methods.The structure was discreted with the space palte-beam composite elements which is proposed by author,general palte-shell elements,space beam elements and space truss elements.The stresses and displacements of the main trusses,concrete slabs,longitude beams and horizontal beams were calculated.The ... |
