The effect of multi parameter changes of arch bridge on buckling analysis of arch bridge

摘要：

　　Based on the data of a arch bridge that lready built up,the finite element analysis model is established by finite element analysis software called Midas Civil.The buckling mode and buckling characteristics of the bridge are analyzed.The following operations changes are performed: the width of the arch rib,the cross section of the arch rib,the cross section of the column,the relative position of the column in the arch rib,etc.he finite element analysis model is established to study the buckling mode of arch bridge under different arch bridge parameters.In the design of arch bridge,the reasonable analysis of the arch bridge is considered.The results show that the stability coefficient of the arch bridge is not linear,but a nonlinear effect.There is a reasonable choice of the multi parameters of the arch bridge,which is related to the use of the concrete arch bridge,the terrain conditions and so on.This paper is to make a basic research to provide some theoretical basis for the design of the arch bridge with reasonable parameters.
