摘　　要：以光谷人民医院工程为例,针对其高位大跨度非对称斜交四塔连体建筑模型进行风洞试验,旨在测量建筑模型上的平均风压和脉动风压时程。通过对所得数据进行处理和计算分析,得出在不同重现期和不同风向角作用下,项目结构表面所受的风压值以及结构在静态和动态状态下的响应,为该项目的抗风设计提供可靠依据。Taking the Optical Valley People’s Hospital project as an example,the wind tunnel test is carried out for its high⁃level large⁃span asymmetric oblique four⁃tower interconnected building model,aiming to measure the average wind pressure and fluctuating wind pressure time history on the building model.Through the processing and calculation analysis of the obtained data,the wind pressure value on the surface of the project structure and the response of the structure under static and dynamic conditions under different return periods and different wind direction angles are obtained.These results can provide a reliable basis for the wind resistance design of the project.
