Concrete structures such as offshore oil platform, nuclear power plant etc. are required to withstand the impulsive load in particular, and an accurate determination of the structural response to impulsive load in the critical region is needed. In this paper, the behavior of high strength concrete slabs under impulsive load was studied in the critical region. An experimental program was carried out to study the effects of both high strength concrete admixtures and curing conditions on the behavior of high strength RC slabs under a given impulsive loading. Four types of high strength RC slabs were tested and the deformation in the critical region, energy absorption at failure, local deformation etc. were compared with each other to examine the contribution of related variables on improvement of the impact resistance. Also the experimental results were compared with the calculated results obtained by using a non-linear dynamic finite element analysis.
