摘　　要：为研究适用于钢结构工业厂房的抗爆加固技术,以钢结构工业厂房为研究对象,开展工业厂房原型结构设计、爆炸载荷的确定及现场毁伤后果评价研究,提出加固技术措施。试验结果表明:在螺栓连接处加垫片、加钢带的加固方式对钢结构工业厂房墙面板抗爆能力有不同程度的提升,在墙面钢板强度足够时,厂房迎爆面上中部檩条跨中部位会出现弯曲甚至断裂破坏。In order to study the blast-resistant reinforcement technology applicable to steel industrial plants,this paper taked steel industrial plants as the research object,carried out the design of the prototype structure ofindustrial plants,the determination of the blast load and the evaluation of the consequences of on-site damage,and proposed reinforcement technology measures.The test results show that the reinforcement methods of addingshims and steel strips at the bolted joints have different degrees of improvement on the blast resistance of thewall steel plate of steel industrial plants.But the bending and fracture damage will occur in the span part of thepurlins in the middle of the blast surface of the plant when the strength of the wall steel plate is sufficient.
