In order to research the failure mode of reinforced concrete(RC) beams under contact explosion, experiments were carried out to explore the damage of RC prototype beams fixed at both ends under four TNT charge masses, the damage failure model and damage effect of RC beams under different charge masses were analyzed. The results show that the beam presents three local failure modes: crater damage, collapse, spall failure and punching failure. The degree of local damage has a serious impact on the overall bending deformation of the beam. Besides, reasonable reinforcement could effectively improve the anti-explosion performance of the beam. The research results could provide a theoretical basis for the design of the anti-blast structures and the damage analysis on the structure subjected to explosive action.
