摘要
为了解按相关规范设计的抗爆结构在多次爆炸荷载作用下的损伤破坏情况,将多次爆炸荷载简化为间隔时间足够长的一系列脉冲荷载;并以典型的钢筋混凝土梁和工字钢梁为研究对象,运用ABAQUS有限元软件对其进行非线性动力响应与损伤破坏的数值模拟研究。分析结果表明:按照相关规范设计、承受一次爆炸荷载作用的钢筋混凝土和钢梁具有较强的承受多次爆炸荷载作用的能力。
In order to understand the damage situations of the blast-resistant structures designed in accordance with correlative criterions under multiple blast loads,the multiple blast loads were simplified as a series of shock loads with enough intervals;taking typical reinforced concrele and double T-steel beams as investigation objects,the nonlinear responses and the damages were simulated numerically by the finite element program ABAQUS.The simulated results indicate that the reinforced concrete and steel beams designed according to the correlative criterions and subjected to only one blast load can resist the multiple blast loads.
