DYNAMIC PUNCHING ANALYSIS OF FLAT REINFORCED CONCRETE SLAB UNDER CHEMICAL EXPLOSION LOADING

Based on the wave propagation theory of the free field in soil under the conventional weapon burst circumstances, the analysis of the punching failure mechanism of slab-column connection is performed using the structure medium interaction theory and the twin shear strength theory. The resistance model of structure and the eqution of motion for the structure are established. The calculated results are in good agreement with the experimental ones.
