Numerical Simulation of Blast Damage in Masonry Walls
In order to study the damage effect of charge explosion on masonry wall, ANSYS/LS-DYNA software was used to simulate the effect of different doses on masonry wall at different burst distances, and the kinetic response process of masonry wall under two dosages of 500kg and 1000kg and different explosion distances was obtained, and the damage mode of masonry wall with different dosages at different explosion distances was analyzed. The results show that with the continuous weakening of the explosion load, the damage mode of the wall is the middle hole, the upper collapse, the middle deformation, the front tipping, the whole collapse, the whole collapse forward, and the partial dumping forward. Taking the middle separation distance and maximum step height of the masonry wall as the standard, when the dosage of 500kg is obtained, the minimum critical damage explosion distance of the wall is 2.5m, the maximum critical damage explosion distance is 3.5m, and the critical damage explosion distance of the wall is 7m when the dose of 1000kg is obtained.
