A Solution Method for Optimal Weight Design Problem of Single Box Culvert Using GA


In this paper, we formulate an optimal weight design (OWD) problem of the single box culvert for a constrained allowable shearing stress of the sidewall, top wall and bottom wall by the slope-deflection method and solve it directly by keeping the constraints based on an improved genetic algorithm (GA). We discuss the efficiency between the proposed method and the traditional method.
