Study on the Influence of Window Glass Size on Blast-Resistant Performance

As the most commonly used exterior-protecting components for buildings, window glass, due to its typical brittle characteristics, is more prone break under action of blast loads and produce high-speed flying fragments, which can pose a great threat personal safety. This paper studies influence size glasses on their failure characteristics. A simplified numerical simulation-based method evaluating P–I (pressure–impulsive) curve glass proposed. The influences length–width ratio, area, thickness curves are systematically investigated. It was found that smaller thicker panel could increase resistance glasses. empirical prediction formulae with different geometrical dimensions established, validity proposed formula verified.
