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.
