The Modeling and Simulation Analysis of Haierwa Reinforced Concrete Arch Bridge

Combining the project of Haierwa reinforced concrete arch bridge,this paper explains the general method for setting up the arch bridge's model by using ANSYS,and t he simulation analysis of static and mode of Haierwa reinforced concrete arch bridge is carried out.The research results indicate that as a whole arch bridge,the natural frequency of Haierwa reinforced concrete arch bridge is closely packed and it is smaller than the higher frequency of Haierwa reinforced concrete arch bridge,therefore,it is accordant with the common rule;Besides,the max displacement of the arch bridge is on the middle spot of the arch bridge and it reduces to two sides gradually and the displacement of two sides goes near to zero.And by calculating and comparing,the arch stiffness meet stiffness requirements;The arch of the bridge is the main carrying part of the bridge by analysis.Therefore,it is accordant with characteristic of the bridge and design idea;The stress of the arch is more uniform that is propitious to the hole bridge;And by calculating and comparing,the strength of the arch meet strength requirements;The structure of the arch bridge is more reasonable.Therefore,the outcome of the paper is very beneficial to designing for other arch bridges.
