减小爆炸破坏的有效方法是在爆炸点与建筑物之间设置一道防爆墙.采用LS-DYNA软件借助已有文献推荐的方法建立数值分析模型.研究了不同药量爆炸荷载下钢筋混凝土防爆墙(RCBW)的破坏过程.提出了 4种不同方案的钢板混凝土防爆墙并对其抗爆性能进行分析、排序.最后,利用RC框架作为防护对象,分析不同钢板混凝土防爆墙的防爆效果.结果表明:爆炸荷载下钢筋混凝土防爆墙的破坏过程分为 3 个阶段,处于第 3 阶段的钢筋混凝土防爆墙发生严重的破坏.相比较于钢筋混凝土防爆墙,4 种不同方案的钢板混凝土防爆墙的抗爆性能均有明显的提高,其中双面钢板混凝土防爆墙的防爆效果最好.爆炸荷载下,经双面钢板混凝土防爆墙防护后的RC框架柱没有发生任何破坏,而经其他 3 种方案防护的框架柱均有一定程度的塑性损伤.
An effective way to reduce the explosion damage is to set up a blast wall between the explosion point and the building.LS-DYNA software was used to establish numerical analysis models with the help of the methods recommended by existing literature.The failure process of reinforced concrete blast wall under different explosive loads was studied.Four different schemes of steel plate reinforced concrete blast wall were put forward,and their anti-explosion performance was analyzed and sorted.Finally,using RC frame as the protection object,the explosion-proof effects of different steel plate concrete explosion-proof walls were analyzed.The results show that the damage process of the reinforced concrete blast wall is divided into 3 stages,and the reinforced concrete blast wall in the third stage is seriously damaged.Compared with the reinforced concrete blast walls,the anti-explosion performance of the steel plate reinforced concrete blast walls with 4 different schemes has been improved obviously,and the double side steel plate reinforced concrete blast walls have the best anti-explosion performance.Under blast load,the RC frame columns protected by double side steel plate reinforced concrete blast walls have no damage while the frame columns protected by the other 3 schemes all have some degree of plastic damage.
