Numerical investigation on impact of bushfire enhanced wind on building structures

![CDATA[Most researches about bushfire and wind, individually focuses on the origins, impacts and reconstruction process which are systematically studied after a devastating event. Indeed, it can reveal a lack of research as both bushfire and wind are interrelated and subsequently referred as ‘bushfire enhanced wind’. This phenomenon has long been acknowledged by researchers, however it’s understanding about the different interactions and effects still remain relatively limited. Therefore, this research addresses the impacts of bushfire enhanced wind over residential structures by numerical investigation using a finite element commercial software known as Abaqus. The model first simulates the most common type of wall system (i.e. masonry: double brick) in Australia with the results presented as pressures and stress distribution. Secondly, the finite element analysis emphasises on the critical sections (i.e. wall and roof connections) when the model contains an opening (i.e. window). The outcomes generated by the finite element analysis are expected to provide valuable understanding into the fire-wind interaction and subsequently impact the Australian Standards aimed at improving structural design within bushfire prone areas.]]
