Abstract

This paper concerns the behavior of a reinforced concrete slab impacted by a block (velocity of about 25 m/s). Experimental campaigns have been led on a one third scale model of an actual structure. It appears that two damaging modes have to be considered: punching of the slab and bending. In this article, we focus on the punching effects. In order to propose a design method of a new concept of rock-shed (Structurally Dissipating Rock-shed), we determine the experimental value of contact time and percussion load. This strength is compared with the punching load of the slab calculated by an analytical model (Menétrey) and a standard code (Eurocode 2). Keywords: rock fall, rock-shed, reinforced concrete, i
