Abstract

Recently, FRP usage for strengthening RC structures in civil engineering has been increasing. Especially, the use of FRP to strengthen structures against blast loading is growing rapidly. To estimate FRP retrofitting effect under blast loading, nine 1000 × 1000 × 150 mm RC slab specimens, which were retrofitted with carbon fiber reinforced polymer (CFRP), basalt fiber reinforced polymer (BFRP), polyurea, and CFRP with polyurea were carried out. The applied blast load was generated by the detonation of 35lbs ANFO explosive charge at 1.5m standoff. The data acquisitions not only included blast waves of incident pressure, reflected pressure and impulse but also included central deflection and strains at steel, concrete, and FRP surfaces. The failure mode of each specimen was observed and compared with a control specimen. From the test results, it was determined that each FRP retrofitted concrete structures showed sufficient retrofit effect under severe damages. It also shows that each retrofit method can be applied to the targeted structures and protection level.
