WIND TUNNEL TEST OF WIND LOAD CHARACTERISTICS OF A MEGASTRUCTURE
-
摘要: 通过风洞试验的方法研究了以矩形为基本截面形状的巨型结构风荷载的特性。给出了巨型建筑表面风压分布规律,同时对大门厅的内风压分布进行了分析。所得的这些结果对结构的抗风设计有较为重要的指导意义。Abstract: By means of wind tunnel test, the wind actions on a uniform rectangle megastructure were studied.The reasonable distribution law of wind loading on the surface of a building could be obtained, meanwhile the wind pressure of the big vestibule was analyzed.The results given by the paper might be a significant guide to wind resistance design of a structure.
