In the realm of long-span steel structures, there exists a diverse array of spatial configurations, and during the construction phase, the load transmission pathways and locations of maximum stress dynamically evolve. To address the intricacies of structural analysis and safety verification during the construction process, an AutoCAD and ANSYSbased plugin for one-click modeling, computation, and results retrieval of large-span steel structures has been developed. This plugin, utilizing the C# programming language to invoke the AutoCAD .NET framework, reads and extracts model information from drawings of long-span steel structures, and autonomously generates APDL command scripts for finite element modeling, computation, and results extraction. This tool is designed for numerical simulation and safety assessment of long-span steel structures during the construction phase. To validate the effectiveness of the developed plugin for long-span steel structure modeling and analysis, a specific single-layer spherical grid shell structure was employed. Using this plugin, a finite element analysis model was rapidly established, and the internal forces and deformations of the structure during the construction phase were verified. The research findings indicate that the single-layer spherical grid shell structure meets the requirements for strength and stability throughout the entire construction process, with internal forces and deformations well-controlled within safe limits and meeting design specifications. The plugin facilitates the efficient and accurate transfer of information from CAD software to CAE software for numerical simulation and safety assessment during the construction process of long-span steel structures.
