波形钢腹板组合箱梁横向内力有限元分析

为研究波形钢腹板PC组合箱梁在局部荷载作用下的横向内力问题,通过对建立与实桥缩尺比为1:5的有限元模型,利用空间有限元对其在局部荷载作用下的横向内力进行了数值仿真分析,并得到其横向内力的有效分布宽度,与规范计算得到的值相对比,表明采用现行公路桥梁设计规范中的有关规定来计算波形钢腹板组合箱梁的横向受力有效分布宽度是安全的...

Finite Element Analysis of Transverse Internal Force of Composite Box-girder with Corrugated Steel Webs

In order to study the transverse internal force of the PC composite box girder with corrugated steel webs under local load,a finite element model with a scaled ratio of 1 to 5 compared with the real bridge is established in this paper.Numerical simulation analysis of the transverse internal force of the composite box-girder under local load is conducted by applying the space finite element method,meanwhile the effective distribution width of the transverse internal force of the box-girder is obtained and then is compared with that obtained by using bridge code.It indicates that it is simply secure to adopt the relevant regulations in the current highway and bridge design to calculate the effective distribution width of the transverse internal force of composite box girder with corrugated steel webs.
