Dynamic Response Test of Reinforced Concrete Slab under Blast Loading

Li, Zhi-Zhong / Tang, De-Gao / Li, Wei-wei / Yan, Zhi-Fang

Reinforced concrete panels were tested explosion for reinforced concrete slab in the dynamic response under blast loading. Dimensions of 1300 mm×1300 mm×50 mm 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.
