ROCKWOOL Roof Solutions Flat Roof See Products Why do we need flat roof insulation? Most thermal transmission is usually through the roofing area. Flat roof insulation is an essential tool that can enhance the energy efficiency of a building and reduce fuel costs. ...
The wind pressure features on a large-span flat roof in uniform flow field and turbulent field induced by conical vortex were studied, through wind tunnel tests. From the comparison of the mean and fluctuating wind pressure distributions on a flat roof in different wind fields induced by conical...
The primary purpose of this study is to provide simple formulas for estimating the design wind loads for the structural frames of flat long-span roofs considering their dynamic response to turbulent wind forces. This paper presents a discussion of the gust loading factor for beams supporting flat...

Although long-span spatial structures have developed rapidly in recent years, considerable uncertainty remains regarding the determination of pressure generated by internal blast loads. This paper focuses on long-span rectangular flat roof as there are significant safety hazards when they are subjected to...
