In this paper, the finite element software ABAQUS is used to simulate the RC beams under the short distance lateral blast load, consider the constraint effect of the plate, and analyze the influence of proportional distance, strength of concrete, strength of reinforcement, ratio of longitudinal reinforcement and other influencing factors on the dynamic response of RC beam. The results show that the CONWEP loading blast is reliable. The proportional distance is less than 0.200, and the lateral blast load has a great influence on the maximum lateral displacement of reinforced concrete beam with plate constraint. The influence of the strength grade of concrete and steel on the dynamic response of RC beams with slab constraints is limited. There is a negative correlation between the ratio of longitudinal reinforcement and the lateral displacement of RC beams with slab constraints. When longitudinal reinforcement ratio is more than 2.11%, RC beams with slab constraint can well resist lateral explosion load, but the lifting amplitude is not obvious.
