A study on the local damage in reinforced concrete slab due to the horizontal impact of steel body with different nose shapes

Abstract

Horizontal impact tests are performed by the impact of a steel body with the mass of 100kg and different nose shapes (hemisphere, conical and flat). In tests, 1.1m square RC slabs are employed for test targets. The steel body is moved by the horizontal impact machine mechanized with rubber bars and controlled by their elongation. The extent of local damage and the damage mechanism in RC slabs due to the impact of rigid body with different nose shapes are investigated. To know the effects of nose shape, the impact force, acceleration and strain at the rear face are measured. The effect of nose shapes on the local damage is discussed using elastic contact theory.
