简支斜交T梁空间受力分析

以北京市通州温榆河西路跨坝河桥为工程实例,结合梁格分析法,建立空间梁格模型,同时考虑斜桥空间上的弯扭耦合效应,得到桥梁上部结构的内力与变形;通过与单梁模型的对比,揭示了斜桥的受力特性,以期为斜桥的设计提供参考.

Analysis on Space Force of Simple-supported Skew T Girder

Taking Beijing Tongzhou West Wenyuhe Road Bridge spanning Bahe River as an engineering example, combined with the beam grillage analysis method, the spatial beam grillage model is established. At the same time, the bending-torsional coupling effect in the space of skew bridge is considered, and the internal force and deformation of the bridge superstructure are obtained. Through the comparison with the single-beam model, the force characteristics of the skew bridge are revealed in order to provide the reference for the design of skew bridge.
