The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes include new design models for wind, bushfire and cold-formed-steel Standards. This will significantly improve the bushfire safety of buildings, since non-combustible steel roof and wall systems are used as building envelopes in bushfire prone areas, but are not designed to withstand recently discovered bushfire-enhanced winds.

该项目旨在研究轻冷型钢屋顶和墙体系统的复杂行为，包括在风和森林大火的共同作用下的局部失效，使用高温下的风吸力试验结合先进的数值模拟。它将产生新的知识的行为和强度的冷型钢屋顶和墙壁系统在丛林火灾条件下。预期的结果包括新的设计模型的风，丛林火和冷弯型钢标准。这将大大提高建筑物的森林火灾安全性，因为在森林火灾易发地区，不可燃钢屋顶和墙壁系统被用作建筑围护结构，但其设计不能承受最近发现的森林火灾增强风。
