连续刚构桥底板钢束布置不同时的径向力比较

Radial force comparison of the horizontally arranged bottom plate of continuous rigid frame bridge

通过比较连续刚构桥底板预应力钢束的布置形式,对其产生的“力”进行有限元对比分析,从而得到此力为指向圆心的径向力,其影响因素有底板钢束布置的角度以及此连续刚构桥的计算跨径。因此,在桥梁设计中,应充分考虑底板预应力钢束的布置形式对桥梁的整体影响。

Through the comparison of the continuous rigid frame bridge floor prestressed steel beam decorate a form,produced the"force"of the finite element analysis comparison,so as to obtain the force to point to the center of radial force and its influence factors are floor the angle of the steel beam layout,as well as the calculation span continuous rigid frame bridge.Therefore,in the design of the bridge,the influence of the layout of prestressed steel bundle on the bridge should be fully considered.
