Abstract
A finite element model is developed in this paper for numerical modeling of the structural responses of FRP-strengthened reinforced concrete panels under blast loading. Strain rate effects for concrete in tension and compression, steel reinforcements and FRP sheets are taken into account in the finite element model. The commercial explicit hydrocode LS-DYNA is employed to carry out the numerical analysis. The proposed finite element model is validated by comparing the computed results of a conventional reinforced concrete panel and FRP-strengthened reinforced concrete panels under blast loading with the test data from the literature. In addition, the effects of FRP thickness, retrofitted surface, standoff distance and the charge mass on the blast resistance of FRP-strengthened reinforced concrete panels are investigated in this paper.
