Windstorm damage surveys highlight that the discontinuity in load resistance and transfer of connections in timber-framed housing can lead to total failure of the roof structure. Field surveys of timber-framed houses under construction in Australia also indicated that, for a typical roof configuration, at least three of its six or more roof trusses had common construction defects (i.e. missing nails) in roof to wall connections (RWCs). It is expected that these construction defects will reduce the capacity and stiffness of the connections, creating variations in the wind load sharing, load transfer and the forces at the roof to wall connection of timber-framed houses.
