一座典型无梁板桥的结构分析

The analysis on the structure of one typical slab bridge without beam

结合某广场四座无梁板桥中较为典型的三号桥,分别利用MIDAS和桥梁博士进行有限元分析,对结果进行对比校验;并探讨了对结构有限元分析时桥墩桩边界条件的简化处理、钢纤维混凝土作为上部结构材料的应用,提出了处理方法。

Combining with the typical third bridge on the four slab bridges without beam on square. It getes the finite dement method by using the MIDAS and bridge doctors to compare the result. Discussing the easy treatment of the bridge pier boundary condition when analyzing the structure finite element method, the application of the upper structure material by using the steel fiber concrete. It also proposals the treatment method.
