Experimental Study on Perforation of Steel Fiber Reinforced Concrete Slab under Impact

Abstract

One of the most important limit states of the member of the concrete structures under impact load like a roof of rock shed is the complete perforation of the member by the falling objects. It has been well known that the characteristics of concrete are improved by the use of fibers. However, the behavior of fiber reinforced concrete slabs under impact has not been clear adequately. Therefore, in the present paper, static and impact tests of the steel fiber reinforced concrete slabs areperformed. Fundamental characteristics of the failure types, energy of perforation, crack surfaces, developments of penetration up to complete perforation are investigated.
