This study investigated the blast resistant performance of RC slabs damaged by a projectile impact. To induce damage in RC slabs, a 46g mass projectile collided with an RC slab. The resonant oscillation tests of the damaged RC slabs were conducted to evaluate the impact induced damage level of the RC slabs. Close-in explosion tests for the damaged RC slabs were conducted to assess the blast resistant performance. Based on the test results, the correlation between the damage level and the blast resistant performance of the RC slab was examined.
