爆炸荷载作用下配筋砌体结构的动力响应

Based on the numerical analysis with LS-DYNA, the deformation and damage of the reinforced masonry walls were investigated by considering the following factors：ｗall-borne constraint, masonry material, strength grade, vertical reinforcement ratio, height-to-span ratio, load peak, distance from explosive center to wall, a hole in the wall and GFRP on the wall. And the distance-time curves of the walls were obtained as well as the stress-time curves of the masonry materials and steel bars. Meanwhile, the anti-explosion performances of the reinforced masonry walls were compared in the different cases and the important factors influencing the structure response were determinded. It is helpful for the anti-explosion design about the reinforced masonry structure.
