Abstract
This paper presents numerical modelling to study potential mitigation methods to improve the impact resistance performance of laminated glass windows against timber windborne debris impact. A detailed numerical model of laminated glass window is generated and validated with laboratory impact tests. The influence of supporting frames made of different stiffness materials is examined. Numerical simulation shows that boundary condition has limited influence to the penetration resistance of laminated glass windows. Then, the dynamic response of doubly laminated glass windows of the same total thickness as that of singly laminated glass windows is studied, which finds that optimization of glass and interlayer layout could effectively improve the penetration resistance of laminated glass windows.
Highlights
In cyclone-prone regions, windborne debris impact poses a major threat to structure and personnel safety in the wake of cyclone incidents
The standard 7.52 mm laminated glass is taken into account
Two 3 mm glass pane with a 3.02 mm Polyvinyl Butyral (PVB) interlayer and two 6 mm glass pane with 1.52 mm interlayer are modelled to check the influence of interlayer and glass pane thicknesses on the overall impact response
Summary
In cyclone-prone regions, windborne debris impact poses a major threat to structure and personnel safety in the wake of cyclone incidents. As the primary concern of laminated glass under debris impact loading in this study is the anti-penetration performance, the unloading behavior is less important; an elasto-plastic material model is utilized, which follows the authors’ laboratory testing data on PVB under dynamic tension.
