Distribution of wind loads in metal-clad roofing structures

The roof is the part that experiences the largest wind load and is usually the most vulnerable part of a house. However, data on how the wind loads are transferred through the roof structure are scarce. The fluctuating nature and variable spatial distribution of wind loads combined with the structural response can cause significant challenges for assessing the distribution or sharing of loads in a roof. Such studies are required to obtain more reliable estimates on vulnerability assessment to windstorms. This paper describes the transmission of wind loads from the pressure on the cladding through the cladding-to-batten connections to the batten-to-truss connections on a roofing system typical of that in many contemporary houses constructed in cyclonic regions of Australia. The study found that the use of normal design practices can significantly underestimate connection loads when highly correlated large-scale wind pressures act on these roof systems.

A new look at smart ventilation for public buildings in the tropics in the post-pandemic era

This paper presents part of a study exploring a quantitative model for linking mechanised ventilation systems to provide acceptable indoor air quality. The lack of an indoor air quality index causes communication discord for occupants, facility managers, and design engineers. Specifically, three statistically correlated indexes to occupants’ health symptoms are the indoor discomfort index, indoor air pollutant index, and indoor environmental index. The model will be validated through empirical data to be collected from occupants of three separate institutional buildings at the James Cook University campus and Cairns City in tropical north Queensland in Australia. The next phase of this project entails the integration of applicable computer-based predictive analytical tools to control mechanised ventilation systems.
