Abstract

This paper presents an experimental investigation of the response of Carbon Fiber Reinforced Polymer (CFRP) strengthened reinforced concrete (RC) slabs under impact loading. Drop-weight tests were conducted to study the effectiveness of CFRP strengthening on RC slabs with or without anchorages in resisting blast and impact loads. In order to approximate a blast event, a water bag is placed in between the test slab and drop weight to generate uniform dynamic pressures over the slab. However, due to repeated bursting of the airbag it was not feasible to continue with this method of testing. As such only three unstrengthened RC slabs were subjected to simulated blast loads. The experimental program was continued subjecting the slabs to direct impact loads via the vertical drop-weight with a hemispherical mass. A control slab, CFRP strengthened slabs and CFRP strengthened slabs with boundary anchors were tested. Each slab was initially subjected to impact from a drop height of 1.5m and then successively loaded from higher drop heights until failure was reached. The results were used to determine the efficiency of CFRP strengthened RC slabs and the effect of anchorage systems to resist impact loads.
