摘　　要：目的研究内置压型钢板装配式宽连梁抗爆性与箍筋配置方式的影响,提出优化连梁抗爆性能的合理方案.方法分别以箍筋直径和箍筋间距为变量、控制变量,建立多组宽连梁有限元模型,进行相同TNT当量下的爆炸模拟及损害特征程度分析.结果爆炸冲击荷载作用下,宽连梁承受荷载过程中的形变值与箍筋直径大小成反比例变化;宽连梁承受荷载过程中的形变值与箍筋间距离值成正比例变化;相同配筋率增长差下,改变箍筋直径对消弱爆炸冲击损害作用明显.结论改变箍筋直径优化内置压型钢板装配式宽连梁抗爆性更为合理.Through the research of influence that explosion and stirrup arrangement,the reasonable scheme on the anti explosion performance of coupling beam is summarized.The finite element model is established which changes stirrup diameter or stirrup spacing,and the bomb simulation and damage characteristic analysis are carried out under the same explosion load.Under explosive impact,the dynamic deformation of wide coupling beam decreases with the increase of stirrup diameter and the decrease of stirrup spacing.Changing stirrup diameter on the weakening explosive impact damage is obvious on the same increase of reinforcement ratio.Therefore,it is more reasonable to optimize the explosion resistance of the wide coupling beam built-in steel plates by change the stirrup diameter.
