摘要
板梁桥设计过程中,铰接板假定通过铰缝在各板间传递剪力起到传递荷载的作用,从而达到板梁桥梁整体受力的目的。桥梁铺装层的刚度相对主梁较小,故往往忽略其作用。但是,通过计算可知,不仅是铰缝,桥面铺装层对空心板梁的横向分布也有很大的影响。基于此,对桥面铺装以及铰缝对空心板梁横向分布系数的影响进行详细的比较分析。
In the design of slab bridge, it is assumed that the loads pass to the entire structure through hinge joint between two interfacing slabs. To simplify the model, only shearing forces are considered in hinge joint. But in reality, besides the hinge joint, bridge deck pavement also affects the transverse distri tion. Such effects were studied in this paper by analyzing the relations between bridge deck transverse distri tion and different hinge joint/bridge deck pavement cases.
