Abstract: As a common type of structure in industrial design, water tank plays an important role in industrial design.In this paper combined with an engineering example, this paper introduces the process of modeling, loading and posttreatment of a reinforced concrete pool by using the calculation software Staad. Pro, and the numerical simulation results are compared with the calculation results of the pool specification, the results show that the results obtained by Staad. Pro can meet the requirements of the code with high accuracy, and can provide reference for the modeling and numerical analysis of similar structures.
