［摘要］结合目前钢结构工程设计的需要，针对钢结构节点设计的特点，利用CATIA二次开发语言Microsoft Visual Basic对CATIA进行二次开发，开发了一款钢结构节点三维设计软件。软件以结构分析模型为基础，对钢结构节点进行设计与验算，并结合CATIA建模特点批量创建钢结构节点的三维精细化模型，实现了分析模型快速输出为更加细节化的物理模型，提高了设计效率和质量。详细地阐述了软件开发的整体架构和关键技术，并通过两个工程实例验证了软件的适用性。

Abstract:According to the current needs of steel structure engineering design and the characteristics of steel structure joint design, secondary development language Microsoft Visual Basic of CATIA was used to carry out the secondary development of CATIA, to develop 3D design software for steel structure joints. Based on the structural analysis model, the software designs and checks the steel structure joints, and combines the CATIA modeling features to create a 3D refined model of the steel structure joints in batches, enabling the rapid output of the analysis model to a more detailed physical model, which improves the design efficiency and quality. The overall architecture and key technologies of software development were explained in detail, and the applicability of the software was verified through two engineering examples.
