提出了一种分析爆炸波与破片联合作用下钢筋混凝土板和拱结构局部与整体破坏效应的工程计算方法,以MK82战斗部在距离结构10m处爆炸为例,采用有限元软件详细分析了爆炸与破片联合作用下结构的局部与整体响应。结果表明,由于爆炸产生的破片先于冲击波达到结构,破片对结构造成的局部损伤对结构整体响应影响不大,结构主要还是受爆炸冲击波荷载的作用。 An engineering calculation method for analyzing local and global failure of reinforced concrete slabs and arch structures under the combined action of blast waves and fragments is proposed. Taking the explosion of MK82 warhead at a distance of 10m as an example, the explosion and Local and global responses of structures under the combined action of fragments. The results show that the fragmentation caused by the explosion reaches the structure prior to the shock wave, and the local damage caused by the fragments to the structure has little effect on the overall structure response. The structure is mainly affected by the shock wave load of the explosion.
