Abstract: This paper presents an analysis of the punching shear resistance of reinforced recycled aggregate concrete slabs. This work mentions several papers focusing on recycled aggregate concrete slabs. Punching shear resistance is assessed according to three design approaches based on standards. This article also describes the design of an experimental programme for the testing of reinforced concrete flat slabs from recycled aggregate concrete. A comparison of the results of analytical calculations and experiments shows that the most accurate design code was the second generation of Eurocode 2 and Model code 2010 with an updated failure criterion when the mean values of the ratio Vtest /Vcalc reached 1.15 and 1.14 respectively. On the other hand, the design code followed by Eurocode 2 provided results with higher safety when the Vtest /Vcalc ratio was 1.41
