Abstract

This paper presents the details of experimental and numerical investigations performed on fabric reinforced concrete (FABcrete) panels under impact loading. Experimental investigations have been carried out using drop weight impact on a square FABcrete panel to study the damage, failure mode and acceleration. The drop weight of 20 kg is used for the study and drop heights have been varied as 100mm, 200mm and 300mm. Numerical simulation of the drop weight impact tests on FABcrete panels have been carried out and observed that there is a good correlation between experimental and numerical predictions. It is observed that the FABcrete specimen with a volume fraction of 1% of fabric withstood an impact force of 50 kN. Further, a high velocity projectile impact on reinforced concrete (RC) slab strengthened with FABcrete has been carried out using nonlinear explicit transient dynamic analysis and observed that the computed penetration depth for RC slab strengthened with FABcrete is lesser compared to RC slab without strengthening, which proves the suitability of FABcrete as an impact resistant material.
