摘要
爆炸可能导致建筑物的严重破坏甚至灾难性倒塌。爆炸载荷作用下钢筋混凝土结构的动态响应与加固技术是当前结构安全问题的研究热点之一。钢筋混凝土梁作为建筑结构的主要承重构件之一,在爆炸冲击荷载作用下发生破坏很可能引起整个结构的倒塌。综述了国内外在爆炸荷载作用下钢筋混凝土梁的动态响应、损伤机理、加固技术等的研究现状与发展趋势,提出了钢筋混凝土梁的抗爆与加固的研究难点和发展方向。
Explosion may lead to severe damage to buildings, even catastrophic collapse, consequently, loss of lives and property. Dynamic response and strengthening techniques of reinforce concrete structure under blast loads are one of the hot topics in structure safety. As one of the main bearing components of building structure, the damage of reinforced concrete beams may cause the collapse of the whole structure under blast loads. A comprehensive overview of research progress of dynamic response, failure modes and strengthening technology of reinforced concrete beams is presented, meanwhile, the research emphasis and main development trend are put forward.
