大型混凝土风洞结构体系温度效应明显,结构支座、剪力墙设计难度较大。利用有限元分析法分析平面C形复杂风洞结构体系在温度作用下风洞结构支座的布置形式。根据支座3种不同的连接形式,对比3种不同的支座设置方案;通过结构固定端剪力墙剪力和关键支座剪力的比较,以及结构体系关键部位的位移的比较,确定结构布置的最优方案。分析在采用最优结构布置方案时风洞筒体在温度作用下板单元温度应力分布情况。
Large-scale concrete wind tunnel structural system temperature effect is obvious, structural support, shear wall design more difficult. Finite element analysis is used to analyze the arrangement of bearing of C-shaped complex wind tunnel structure under wind pressure. According to the three different forms of support, three kinds of different support arrangements are contrasted. By comparing the shear force of the shear wall at the fixed end of the structure and the shear force of the key support and the displacement of the key parts of the structure, the structure Optimal arrangement of the program. The temperature stress distribution of the plate unit under the action of temperature is analyzed with the optimal structural layout scheme.
