文章对现浇箱梁预应力顶板张拉带来的梁端局部应力作了细致分析,采用目前通用的Ansys有限元软件建立三维实体模型,并与杆系模型就应力分布、底板裂缝控制等计算结果进行对比,得出简化计算方法。得到结论对既有同类桥梁有一定的参考和借鉴意义。
In this paper, the local stress of the beam end caused by the prestressed cast-in-place box girder is carefully analyzed. The three-dimensional solid model is established by using the current general Ansys finite element software and is compared with the rod model for the stress distribution and floor crack control The results are compared to arrive at a simplified method of calculation. It is concluded that there is some reference and reference for the existing bridges.
