Of the damage sustained by residential buildings during a severe wind event, a significant portion can be caused by impacts from wind‐borne debris. Furthermore, where such impacts form dominant openings in windward walls, large internal pressures can be generated, consequently leading to substantially increased loads on the building’s structure and hence increased damage to the building’s envelope. Geoscience Australia, together with its collaborators the Cyclone Testing Station at James Cook University and JDH Consulting, have commenced development of a software tool to quantitatively model vulnerability of residential buildings to severe wind. This paper describes the implementation of the methodology presented in Part 1 [1] into the software tool to model wind‐borne debris induced damage.

Damage from windborne debris is a major contributor to the total damage produced by extreme wind of all types. Therefore it is important to incorporate this component into a complete wind-induced damage model, developed for disaster management or insurance purposes. This paper describes the basic methodology for windborne debris damage modelling developed for Geoscience Australia as part of the VAWS model. VAWS is a software tool currently under development that models damage to buildings from severe wind. The implementation of the windborne debris damage model is described in Wehner et al, 2010.
