“…The uplift capacities for roof connections are modelled to follow a lognormal distribution [23]. For CTB and BTR connections, the uplift capacities are taken as the lower of the pull-out and pull-over strengths, and the uplift capacities for triple grip RTW connections fastened using hand nails and gun nails are the peak loads in the load-deflection curves obtained from experiment tests [31]. Note that the RTW connections are different for houses with design wind classifications of N2 and N3, while the CTB and BTR connections are identical for N2 and N3 designs.…”

This chapter presents a probabilistic approach to assess the long-term economic risk and cost-effectiveness of relevant adaptation measures for Australian housing exposed to non-cyclonic extreme windstorms under a changing climate. The proposed method provides decision-support for the long-term adaptation of residential communities to extreme windstorms and climate change. The cost-benefit analysis suggests that, for all considered climate scenarios, strengthening roof cladding connections is not cost-effective, while improving window resistance or installing window shutters is more cost-effective.

“…The losses are estimated in terms of cost ratios, which is defined as the ratio of the cost to complete the subassembly to the building value. The estimated total cost to build a new contemporary house with an approximate floor area of 150 m 2 is L building = $300,000 Australian Dollars [14,30]. Based on cost data provided by Australian housing cost guides [29] and subjective judgement, the subassembly cost ratios for new construction are estimated for a representative contemporary house built to an average standard.…”

Climate adaptation measures improve housing resilience to extreme winds, and reduce economic losses associated with wind and rainfall damage under a changing climate. Several adaptation measures are adopted in this study for Australian contemporary houses subjected to non-cyclonic windstorms to either reinforce the building envelope or increase the water resistance of building interior. A risk-based cost-benefit analysis is conducted to evaluate the cost-effectiveness of these adaptation measures that considers the effect of construction defects. It was found that the annual expected losses for houses in Brisbane with construction defects are considerably higher than those without considering construction defects, whereas the influence of construction defects is lower for the Melbourne houses. The cost-benefit analysis reveals that strengthening windows is cost-effective for Brisbane and Melbourne houses. Installing window shutters significantly reduces economic risks associated with extreme winds and is costeffective for houses in Brisbane. Adaptation measures are generally not cost-effective for Melbourne houses due to lower extreme wind speed and associated rainfall.
