Abstract:: It was complex and repetitive to establish a finite element model for large steel silos in the actual project. To solve the problems, the OAPI plugin of rapid modeling, applying loads and extracting main results for steel silos was developed using C[KG-*3]# language on the.NET platform. Moreover, the API functions of finite element analysis software SAP2000 and the development procedures of plugin were introduced, an actual engineering example demonstrated that the OAPI plugin was feasible. The analysis results show that it is convenient to develop the plugin which applies for parameterized modeling and analysis of large steel silos with new types of walls and columns based on C# language on the .NET platform calling the API functions of SAP2000. The research work can help further application of SAP2000 in designing and analysis of steel silos and can provide some references for parameterized modeling and analysis of similar engineering in the future.
