Optimization Analysis of Thin-walled High Pier

摘要

According to the restriction of the stability and intensity, size optimization of the high piers' section is calculated by using the current FEM software ANSYS, by means of differential coefficient. The results of the calculation and analysis indicate that the parameter optimization of the piers' section of Long-span continuous rigid frame bridges is feasible by using the optimization model together with the finite element method, and the results are provided reference for optional design of similar bridge
