| Abstract | ||
| This Paper is conducted to investigate experimentally the punching shear behavior of hybrid flat plate. Five slab specimens with (1000x1000x70) mm dimensions have been tested, two of which have been made fully with High Strength Concrete and Steel Fiber Reinforced Concreter , while, the others have been made by mixing two types of concrete (Steel Fiber Reinforced Concreter in the critical zone and High Strength Concrete in the other part of slab specimen). The slab dimensions, main reinforcement have been kept constant in all slab specimens. The variables are concrete type and dimensions of critical area. Experimental results show that the use of SFRC improves the punching shear resistance and allows higher forces to be transferred through the slab-column connection. For slab specimen which made fully with SFRC, the ultimate shear capacity increased by (25%) in comparison with the normal slab. While, for slab specimens which made with hybrid concrete the ultimate shear capacity increased by (5%-13%) in comparison with the normal slab. | ||
