Numerical Study on the Behaviour of Hybrid FRPs Reinforced RC Slabs Subjected to Blast Loads

The safety of civilian and military infrastructure is a concern due to an increase in explosive risks, which has led demand for high-strength civil with improved energy absorption capacity. In this study, Finite Element (FE) numerical model was developed determine the effect hybrid Fibre Reinforced Polymer (FRP) as strengthening material on full-scale Concrete (RC) slabs. reinforcing materials under consideration were Carbon (CFRP) Glass (GFRP) fibres, subjected blast loads structural response. A laminated composite fabric utilized failure composite, facilitates strain rate effects. damaged area laminate determined FE model, it good agreement corresponding experimental results literature. Models containing different stacking sequences built demonstrate their efficiency resisting loads. general, reduced when reinforcement CFRP top layer used.
