The invention relates to a method for designing steps of a weight-reducing container ship. The method comprises the following steps: S1, determining an initial arrangement scheme of steps in a container cabin; s2, determining a structural area in which optimization design can be carried out on the bow and the stern; s3, selecting proper optimization software to carry out modeling of optimization calculation; s4, performing topological optimization analysis on the initial step based on a minimum density method; s5, on the basis of a topological optimization result, engineering scheme design is carried out on the step area; and S6, calculating the bearing capacity of the optimization scheme on the container. According to the method for designing the steps of the weight-reducing container ship, a platform is replaced by the steps of the container through the supporting columns or the girders and the like, the structural weight can be reduced, the purpose of light weight is achieved, the replacement mode is simple, and the construction difficulty can be reduced.
