Analysis of Load Transverse Distribution Coefficient for Rigid Frame Arch Bridge

Xuemei Zong

Abstract

ANSYS,a large-scale general program for structural analysis is applied to build its spatial model according to design feature of rigid frame arch bridge.The load transverse distribution coefficient of some special structure point is calculated by flexibility method.Some kinds of graphs are plotted according to the analyzing result,and the result reveals the different variation law of load transverse distribution coefficient along the longitudinal and crosswise,if the simple mid-span load transverse distribution coefficient is adopted,there will be great deviation in calculation.The paper also draws its sampling principle for rigid frame arch bridge in simplified calculation,and its necessity for spatial structural analysis in engineering practice.
