|
摘要
板锥网壳结构是由薄板及钢管组合而成的一种轻质高强、技术经济效益良好的新型空间结构.本文应用谐波法模拟板锥网壳结构所受风荷载,并研究其风致响应特性.根据板锥网壳结构特点,基于CFD方法,采用数值风洞技术模拟结构周围风压变化,得到了板锥网壳结构的风荷载体型系数,并和荷载规范推荐的常规网壳结构的风荷载体型系数进行了比较.采用结构通用分析软件,通过模拟结构周围风压变化,对板锥网壳结构进行了风振响应时程分析,并对不同材料的板锥网壳结构风振响应分析结果进行了对比.为板锥网壳结构的抗风设计提供理论依据,得到了一些可应用于工程实际的重要结论.
Plate-cone reticulated shell is a new type of space structure which has good mechanical behavior,technical economy and architectural appearance.In the paper,fluctuation wind loads are simulated using the wave superposition method,and wind-induced responses characteristics of plate-cone reticulated shell are studied.According to the structural behavior of plate-cone reticulated shell,the shape factors were gained by numerical wind tunnel tests based on computational fluid dynamics method through simulating wind field variations around plate-cone reticulated shell,and compared with common reticulated shells' shape factors of wind load suggested by the code.By using the structural analysis software,time domain analyses of wind resistance of plate-cone reticulated shell are carried out through simulating wind field variations around the shell,and wind-induced response of models with different material are compared.Some important conclusions for wind resistance of plate-cone reticulated shell are obtained for practical design.
