The report presents conclusions on the critical wind loads of tiles on pitched roofs. Because of gaps between the roofing tiles, these types of roof tiles are wind permeable. The net wind load on roofing tile is determined by the external pressure distribution on the roof surface and the internal pressure distribution underneath the roof covering. The external pressure distribution depends on the building flow field and changes in the local flow due to the shape of the roofing tiles. The internal pressure distribution is influenced by the local direction with respect to gaps between the roofing tiles and the resistance of the flow underneath the permeable covering. The critical loading on a roofing tile did not necessarily occur for the critical external pressure distribution on the roof surface.

该报告提出了关于斜屋顶瓦片临界风荷载的结论。由于屋顶瓦片之间的间隙，这些类型的屋顶瓦片是透气的。屋面瓦上的净风荷载由屋面表面的外压力分布和屋面覆盖层下的内压力分布决定。外部压力分布取决于建筑物流场和由于屋顶瓦片形状引起的局部流的变化。内部压力分布受相对于屋面瓦之间的间隙的局部方向和可渗透覆盖物下方的流动阻力的影响。屋面瓦上的临界荷载并不一定发生在屋面上的临界外压分布上。
