The random wind pressure field of a pitched roof is predicted in terms of the proper orthogonal decomposition (POD) technique.
应用本征正交分解(POD)技术对双坡屋盖的随机风压场进行了预测。
The wind tunnel tests of several typical large roofs,including a pitched roof,domes and a cylinder,were carried out with various terrains which cover uniform approach,suburban and urban exposures.
发现位于双坡屋盖的屋角、屋檐及屋脊区域的风压远大于其它区域的风压,均匀流中这些屋盖的平均风压是市郊地貌屋盖的2至3倍,而市郊地貌屋盖的平均风压又是城市地貌屋盖的2至3倍。
This paper discusses the application of Proper Orthogonal Decomposition (POD) to the reconstruction of the random wind pressure field acting on a pitched roof.

The numerical simulation techniques are employed to study a common two dual-slope roof the same before and after the light steel plant layout,in different distances and different wind directions its roof and wind pressure changes in the interaction.
采用CFD数值模拟方法探讨了常见的两栋相同的双坡屋面轻钢厂房前后布置时,在不同距离不同风向角下其屋面风压的变化及影响,并与单体工况比较,获得了群体效应下低矮双坡屋面房屋的屋面风压的分布规律和特性。
To study the influence of different roof pitches on the wind pressure of the surface of greenhouses with double-pitch roof,based on turbulence k-ε model and wall function method,greenhouse structures were dispersed by member FEM.
