Abstract: In recent days, reinforced concrete (RC) structures are highly affected by impact loading. In many places, the external surface of the structure is mainly prone to damage that are caused due to the impact of heavy mass substances like projectile, missile or aircraft impacts, terrorist attacks, and ice impacts. To resist the damages occurring due to impact in RC structures, geogrid material is utilized as an addition to steel reinforcement. This paper experimentally presents the impact behavior of reinforced concrete slab with geogrid as an additional reinforcement. Geogrid is one of the geosynthetic material that exhibits both tensile and flexural behavior similar to that of steel. The geogrid reinforced concrete slab was tested experimentally under drop weight impact loading using a steel ball having a mass of 7 kg with constant drop height of 3.4m. The impact behavior in terms of energy absorption was measured experimentally and was utilized to compare with results of Finite Element Analysis (FEA) carried out in ABAQUS software. The energy absorption, stresses, displacements, displacement versus strain energy and damage patterns were taken from the FEA. The results obtained for conventional and geogrid reinforced concrete slab were compared and discussed. The obtained results showed that the addition of geogrid layer increases the impact resistance than conventional reinforced slab.
