![]() ![]() The experiment results show that: The maximum regional average wind pressure coefficient occurs when the radial distance is 1.25 D jet ( D jet is the spout diameter) and the wind direction angle is 0° As the radial distance increases, the average wind pressure coefficients of windward firstly increase fast and then decrease, the coefficients in other areas increase first and then tend to be stable The wind direction angle greatly affects the average wind pressure of each area. The influence of the radial distance and the wind direction angle on the average wind pressure in different areas on the roof was investigated. The wind pressure characteristics of rhombus hyperbolic-paraboloid roof under the action of downburst were investigated by the test. A rigid model test under the action of a downburst was carried out. ![]() The scale model of a large-span structure with rhombus hyperbolic-paraboloid roof was designed.
