Wind loading on loosely laid pavers and insulation boards for flat roofs

摘要: Abstract The paper gives results of experiments and calculations concerning the safety against wind lift-off loosely laid pavers insulation boards on flat roofs. are aimed to derive information underelement pressures depending external pressure distribution windpermeability layer consisting or boards. Theoretical considerations lead a simple equation for determining failure speed pressure, relative element size area weight elements. given as diagrams which may help designer choose best possible solution when using additional thermal roof ballast.
