摘要：

Reinforced concrete panels were tested explosion for reinforced concrete slab in the dynamic response under blast loading. Dimensions of 1300mmx1300mmx5Omm plates under different reinforcement ratio were designed. Explosion test was carried out for three different batches of reinforcement ratio reinforced concrete slab in the explosion simulator. The load was calculated using empirical formulas. Blast loading time curve was obtained by the explosion test and the correctness of the numerical simulation method was verified. The results indicate that reinforced concrete slab under blast loading is different from static damage destruction. Diagonal cracks appear on plat under the blast loading destroyed. When the peak load is large, a large square cracks plate was appeared in the middle of the plate and accompanied diagonal cracks. When the peak load is small, diagonal cracks develop fully, square cracks were smaller.
