Abstract

In this study, effects of reinforcing on the damage of reinforced concrete slabs subjected to Explosive loading has been experimentally investigated to improve the design and damage estimate methods of reinforced concrete structures. Explosive Pentolite were detonated on the surfaces of seven kinds of reinforced concrete labs, with different reinforcement. After the tests, the damage in the slabs was observed in detail and analyzed for the crater, spall, breach and crack. The tests results showed that reinforcing using steel net or high ratio of steel bars in reinforced concrete slabs are slightly effective to prevent the damage of crater and spall depth, but aren't to prevent spall perfectly, and so on.
