Dynamic Analysis on Explosion Resistance Performance of Reinforced Concrete Wall

Abstract:

Based on the finite element software ABAQUS, this paper deals with numerical simulation to dynamic response of reinforced concrete wall under blast loading. Study shows that the explosion resistance performance of the wall with four edges fixed or with two opposite edges fixed are better than that of the wall one edge fixed and another opposite edge simply supported. The greater the explosion impulse, the bigger the maximum displacement of the wall. When reinforcement ratio of the wall increases, the explosion resistance performance of the wall will be improved. At the same time, reasonable reinforcement and external conditions should be made sure. Keywords: Blast Loading, Numerical Simulation, Shear Wall, Dynamic Response
