Study on impact resistance of fiber-reinforced recycled concrete slab based on ABAQUS

Abstract

In this paper, ABAQUS numerical simulation is used to study the impact resistance of waste fiber recycled concrete slab with 50% replacement rate of recycled aggregates and 0.08% and 0.12% volume addition of waste fibers. The impact times at the initial crack of RC50, RC50-0.08, and RC50-0.12 are 10, 17, and 21 times respectively. With the increase of the volume of waste fibers, the impact resistance of recycled concrete slabs is enhanced. The addition of waste fibers inhibits the development of cracks under impact force, to improve the impact resistance.
