摘要
将箱梁预应力横隔梁视为单一构件 ,通过桥梁空间程序计算出最不利的横隔梁的弯剪等内力值 ,根据弯矩、剪力与分布荷载集度间的关系原理 ,求算出等效荷载 ,将等效荷载应用到平面杆系桥梁程序中 ,对横隔梁进行预应力配索设计 ,并通过设计实例予以详细介绍。
The prestressed concrete cross slab in box girder is regarded as a single element when calculation will be made using bridge space computation program to clarify the most unfavorable magnitude of its internal forces such as: shear stress, bending moment, etc. According to the relationship among bending moment, shear stress and distributing load density, equivalent load could be calculated, and the equivalent load is applied to plane pole system Bridge Computational Program. The design of a prestressed cross slab in box girder is given in this paper.
