Abstract

Windstorms cause most of the damage to houses worldwide. The roof is usually the most vulnerable part of the house. However, information on how the wind loads are transferred through the roof structure is scarce. The fluctuating nature and variable distribution of wind loads, combined with the change from linear to non-linear behaviour as the loads increase, can cause significant challenges for the assessment of structural loads. This paper studies the transmission of wind loads from the pressure on the cladding through the cladding-batten connections to the batten-truss connections as the wind loads increase for a roofing system typical of that in many contemporary houses constructed in cyclonic regions of Australia. The study found normal design practices can produce significantly lower connection loads for these roof systems.
