| dc.description.abstract | This study investigates the effect of free air and underground blast on the concrete structure. The propagation of the blast wave and its effect on the concrete structure was simulated. Due to the difference of the medium, the speed of the pressure propagation from free air blast was faster than the underground blast. The peak pressure in free air blast was three times higher than that in underground blast. Also, arrival time of the peak pressure was 26 times faster in the free air blast. Pressure rise time, positive duration time, and negative duration time in the underground blast were longer than those in the free air blast. The behavior of the concrete structure was also predicted. In the case of free air blast, the top and side surfaces of the concrete structure failed. However, in the case of underground blast, only the top surface of the concrete structure failed. | - |
