Abstract

In this paper, the Explosion Wave effect on Prestressed Concrete shells was numerically discussed. For this purpose, at first, a semi cylindrical shell roof without pre-stressing imposed by an explosion of a ton of TNT at a distance of 10 meters from the center line of the structure. The finite element analysis was performed by Abaqus software and the results of tensile and Compression Failures are extracted and verified by the results of the literature. In order to investigate the effect of pre-stressed tendons in longitudinal direction on mises stresses and tensile and Compression Failures, the semi cylinders were pre-stressed by 3 MPa, 5 MPa and 8 MPa. In addition, the effect of the span length on the results of mises stresses and failure modes was evaluated using three lengths of 30, 45 and 60 meters. The results of the analysis showed that the pre-stressed structures would reduce the damage caused by the explosion. Increasing the span length causes the failure to focus on longitudinal symmetrical axes.
