巨型框架刚性模型风荷载特性的风洞试验研究

Experimental research of wind load on a rigid model megastructure in wind tunnel test

给出了以矩形为基本截面形状的巨型框架结构刚性模型测压试验方法和试验内容,分析了风洞试验得到的风压值,提供了巨型框架建筑表面风压分布规律和体型系数。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。

The research presents a wind tunnel test on a uniform rectangle megastructure. The pressure distribution of the models were measured. It gives the means and content of the test. The reasonable estimation of wind loading on the surface of building could be obtained, meanwhile the wind pressure in the big vestibule were induced.
