应用自行研究开发的门架钢结构优化设计软件SOA对数百个工程实例的优化分析设计证明 ,应用该优化方法不仅能提高设计效率 ,节省钢材 (与常规设计相比一般可节约钢材 15 %以上 ) ,而且使结构受力更加合理 ,安全度普遍提高 .本文对该门架结构实用优化设计方法及相应的优化分析软件作了简要介绍 。

Successful application 0f the optimum design software for door\|shaped steelframe structures SOA developed by the authors to the analysis and design of hundreds of practical engineering projects indicates that, by using the proposed optimum analysis method the design efficiency can be considerably raised and the steel use can be significantly economized (in general the steel use can be saved by more than 15 percent compared with that using the conventional design method). Meanwhile, the internal forces of the structure tend to be more reasonably distributed and the degree of structural safety be generally raised. This paper briefly presents this practical optimum design method and its computer software. Real engineering examples are analyzed and compared with that using the conventi0nal analysis method for demonstration of the effectiveness of the present method. \;
