重庆两江新区某双层库钢结构设计

Design of a Steel Double-story Warehouse of Liangjiang New Area in Chongqing

某双层库钢结构设计方案采用极少见的框架上门式刚架结构体系,阐述了该结构体系底部框架顶部门式刚架的特点和难点,并介绍了主要仓库荷载的取值,采用PKPM结构计算软件进行三维钢结构建模计算分析,同时采用三维通用有限元软件MIDAS GEN进行对比计算分析,检验了该结构体系设计的合理性。

The design scheme of a steel double-story warehouse adopts a rare structural system with a portal frame upon a steel frame,the structure characteristics and key design problems are introduced,and the value of main warehouse load is introduced,the 3d steel structure modeling are analyzed by PKPM structural software. At the same time,a comparative analysis are adopted by a 3d general finite element software MIDAS GEN. Finally,the rationality of this structural system are examined.
