Abstract

In this paper, by using ANSYS software under the working condition of the most unfavorable load small railway steel Bridges the strength of the initial model is used for calculation, by calculating the initial model satisfies the requirement of strength and stiffness; Second, the initial model for the optimization design, and select reasonable according to the results of the optimization design theory of i-steel to replace all beams in the initial model; In the final analysis to calculate the optimization model of strength, stiffness and weight of steel, the optimization model in meet the design requirements at the same time than the initial model saves 23.98% of the conclusion of h-beam steel.
