Abstract
M.Ing.
In this study a comparison is made between the punching shear capacities of square slabs
reinforced with 3CR 12 corrosion resisting stainless steel and high tensile strength carbon
steel. A square column 11 0 mm x 11 0 mm is used to simulate the point load on the slab.
Three different slab depths were chosen for the experimental procedure. The South African
concrete design specification SABS 0 I 00, the Eurocode concrete design specification and
Menetrey's design model are used to determine the theoretical punching shear capacities of
the slabs.
It is concluded in this study that the procedures described in the concrete design codes and by
Menetrey to determine the punching shear stress of concrete slabs reinforced with high
strength carbon steel reinforcing bar compare well with the experimental results when 3CR I 2
corrosion resisting steel is used as reinforcing bar in concrete. The experimental results do not
compare well with the theoretical results when the new Eurocode is used.
