Abstract: With rapid development of computer technology, a lot of finite element analysis softwares have been widely used in structural fields. Users of these softwares should have deep and professional knowledge background, but using methods of these softwares is so complex and it is difficult for ordinary shelf designers to master them in short time. In this paper, a kind of new structural analysis software is developed, the interface data file is used in the new system, and finite element solver of SAP84 is called by VB tool through programming for a secondary development of the calculation module. It develops a general calculation of steel shelf system successfully. This system has a friendly, convenient and easy using interactive interface, and it is helpful for engineers to design steel shelves.

摘要： 随着计算机技术的飞速发展，有限元软件在结构分析领域得到了广泛的应用。但因其需要掌握的专业基础知识深，操作流程复杂而很难被普通的货架设计人员在短时期掌握。以数据文件为接口，利用VB进行编程调用有限元软件SAP84的计算模块进行二次开发，实现了钢结构货架通用计算分析系统（简称ASSRS系统）。此系统具有友好、方便、易用的人机交互界面 为钢结构货架的合理设计提供了帮助。
