Steel Box Single-ribbed Tied Arch Bridge Finite Element Model Calculation and Analysis

Han Yong-hua

Abstract

Steel box single-ribbed tied arch bridge finite element analysis is study,with Baisha River Bridge which is under construction in Guangzhou for engineering background,by using special finite element software bridge MIDAS /CIVIL establishment of full-bridge space model.The most unfavorable condition of the deflection,stress is calculated.Assess its structural safety,the results show that:in the design of the bridge deflection under load is less than specification value,the maximum stress under load combination does not exceed the material yield strength,and has a certain stress safety factor.
