Research Abstract

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.
