Blast response of RC slabs with externally bonded reinforcement : experimental and analytical verification
Abstract
The present paper provides an analysis of the efficiency of externally bonded reinforcement (EBR) on reinforcedconcrete (RC) slabs under blast loads. Five simply supported slabs with a span of 2m are tested under explosivecharge. One of the slabs is used as a reference specimen and the remaining slabs were strengthened with differentratios of carbon fiber reinforced polymer (CFRP). An analytical analysis is carried out using the simplified singledegree-of-freedom (SDOF) approach to predict the maximum deflection at midspan. Digital image correlation(DIC) is used to measure the maximum deflection at the midspan of the slab and the strain distribution in theconcrete and the EBR. Given the challenge to combine these displacement field measurements with blast, anexplosive driven shock tube method has been adopted in this study. The results indicate that CFRP as EBRincreases significantly the flexural capacity and the stiffness of RC slabs under blast loads. The impact of the blastwave on the RC slabs generates high strains in concrete, steel reinforcement and CFRP strips. Good correspondencein the prediction of the maximum deflection between the experimental and the analytical results, isobtained, showing that analytical analysis by means of the simplified SDOF approach leads to a reliable prediction.
