Abstract

Most of the recent studies have emphasized the effect of the positive phase of blast loading while determining the structural response. The effect of the negative phase on the dynamic structural response has been ignored. This research focuses on the effect of the negative phase of a blast loading on the dynamic response of an architectural laminated glass. A closed-form solution based on the classical plate theory is developed and then the results are compared with a 3-dimensional nonlinear dynamic finite element analysis. Results indicate that the negative phase of a blast loading has a significant effect on the dynamic response of the laminated glass panel. In particular, mid-span panel deflection and stress due to negative phase pressure are almost double the corres
