Research on Optimization Design for Reinforcing Method of Irregular Cross-Section Arch

Abstract:

This article makes finite-element simulation and analysis on a reinforced two-way curved arch bridge by means of ANSYS, a tool of finite element numerical analysis. Through comparison with the testing results after reinforced, it validates feasibility and reasonability to analysze a reinforced two-way curved arch bridge using a physical unit of ANSYS. On basis of this, it brings forward an idea of optimization design and researches the real two bridges for optimization of reinforcement using ANSYS analyzing and mathematically statistical method. Through effects after and prior optimization, it demonstrates necessity for optimization design of reinforcement and attains some significant conclusions which provide theoretical basis to direct production in the future.
