摘要
某曲棍球基地看台罩篷采用悬挑管桁架结构。较系统介绍了悬挑罩篷的设计过程,重点介绍了设计中针对悬挑结构冗余度较低、罩篷曲面部分位置曲率较小及施工原因存在的非平直杆件问题所进行的考虑双重非线性的整体屈曲分析、考虑非线性屈曲的非平直桁架弦杆分析、考虑接触非线性及材料非线性的销轴节点分析,提出了桁架非平直弦杆计算中的处理方法。
The steel-awning of a hockey base sport stadium was designed with steel truss. Design of this roof structure was discussed in this paper and several key points were introduced. Nonlinear buckling analysis, progressive failure analysis, and analysis of pin connections were presented. Special design methods of this non-plane truss were systematically described, which could be referred by similar engineering projects.
