This study is conducted to investigate experimentally the punching shear and flexural strengths of reinforced concrete flat plate slabs made with Non-Rectangular (triangular and trapezoidal) shaped. Four test self-compacting concrete slab groups were manufactured, each of which consisted of three slab specimens identical in size and shape but different in constituent’s properties. All slabs are simply supported along the all edges and subjected to single point load applied at the center of gravity of each slab.
Experimental results shows that the use of self compacting concrete improves the punching shear resistance and allows higher forces to be transferred through the slab-column connection. For slabs which were designed to fail in punching shear, the ultimate capacity of the tested specimens increased by (7%) to (20%) when the shape of slab specimens changed from triangular to trapezoidal. In contrast of slabs which were designed to fail in flexure, the ultimate capacity of the tested specimens increased from (16%) to (58%) when the shape of slab specimens changed from triangular to trapezoidal.
The cracking load depends essentially on concrete strength and not on slab configuration, but, the ultimate capacity depends on both, concrete strength and shape of slab.
