Modelling the vulnerability of a high-set house roof structure to windstorms using VAWS
Conference Publication ResearchOnline@JCUAbstract
Modelling the vulnerability of houses in windstorms is important for insurance pricing, policy-making, and emergency management. Vulnerability models for Australian house types have been developed since the 1970s and have ranged from empirical models to more advanced reliability based structural engineering models, which provide estimates of damage for a range of wind speeds of interest. This paper describes recent developments in the engineering based vulnerability modelling software: ‘Vulnerability and Adaption to Wind Simulation’ (VAWS), which uses probability based reliability analysis and structural engineering for the loading and response coupled with an extensive test database and field damage assessments to calculate the damage experienced by selected Australian house types. A case study is presented to demonstrate the program's ability to model progressive failures, internal pressurization and debris impact.
