Description

This paper presents an experimental program conducted to investigate the punching shear behaviour of self-consolidating (SCC) two-way slabs, and the influence of using different sizes of coarse aggregate and slab thickness on this behaviour. For this purpose, a total of six slabs were tested. Two groups of labs with targeted compressive strength of 30 MPa were used; for group A, 10 mm coarse aggregate size was used, and 20 mm coarse aggregate size was used for the slabs in group B. Each group consisted of three slabs with different thicknesses of 150, 200, and 250 mm. The results revealed a significant effect of slab thickness and size of coarse aggregate. The failure criterion proposed by (Muttoni 2008) based on the slab rotation was used to predict the tested slabs capacities. In addition, comparison with other codes of practice (CSA A23.3-04, ACI 318-11, BS8110-97, and EC2) was carried out. These codes except the EC2 can be safely used to check the punching shear capacity of SCC slabs without the need of any modification to the equations used.
