The personal awareness of explosion protection increases consequently with the terrorist threat throughout the world in recent years, so explosion protection becomes a worldwide problem. People pay more and more attentions to the explosion-proof of building. Glass window is the weakest component of a building. Therefore, it is very important to study the explosion-proof performance of glass windows for improving the building protection capability. The experiment is the most intuitive method to detect the explosion-proof performance of glass windows. The critical safety distance of the glass window under small explosion load was measured by experiment in this paper. However, due to the high risk and cost of explosion experiments, so the experiment data were rather rare. For comprehensive understanding the explosion-proof performance of laminated glass windows, the critical charge for double laminated toughened glass under explosion was simulated. According to the fitting curve of critical charge, the empirical formulas for calculating the critical charge for laminated glass windows with three panel sizes, three glass thicknesses and four interlayer thicknesses are obtained at different distances. The error analysis shows that the empirical formulas are accurate and available, which can provide some reference for the anti-explosion design of laminated tempered glass.
