Numerical Simulation of Blast Loads of Building with and without Glass Window

[摘要] A typical building model with and without glass windows has been constructed in the present paper using LS-DYNA to calculate the blast loading acting on it. For the without glass window case, the window is assumed to be an opening and there is no glass. Scaled distances of 0.5 m/kg 1/3 , 1.0 m/kg 1/3 and 2.0 m/kg 1/3 are considered. The peak value of the overpressure at some typical positions inside the building are obtained and compared. The peak pressure distribution of each wall surface and the ceiling are obtained, and the influence of glass on the explosion load under different scaled distances is attained. It is found that the smaller the scaled distance, the less obvious the blocking effect of glass, and the glass can be ignored in the simulation. As the scale distance increases, the barrier effect of glass becomes more obvious. At this time, simply ignoring the glass may cause error.
