大学生结构设计竞赛是培养土木工程专业学生创造精神、动手能力和团队协作意识的重要平台。文章提出概念设计、优化分析、模型制作是结构设计竞赛的三个重要方面,对比分析了目前国内常用结构分析软件的特点,提出MIDAS是指导大学生进行结构模型优化分析的一个很好工具。以湖南省大学生第四届结构竞赛为背景,总结了MIDAS建模分析基本流程及其关键要点,供模型比选、结构优化设计参考。
The structural design competition for undergraduates is an important platform for cultivating civil engineering students’ awareness of creating spirit, practical ability and teamwork. The article puts forward that concept design, optimization analysis and model making are three important aspects of structural design competition. By comparing and analyzing the characteristics of commonly used structural analysis software in China, it is proposed that MIDAS is a good tool to guide college students in optimizing structural model. Taking the fourth competition of college students in Hunan Province as a background, the basic process of MIDAS modeling and analysis and its key points are summarized for reference of model selection and optimization design.
