Abstract

High strength reinforced concrete plates are commonly used for bridge decks. tong span structures, marine platforms, and offshore structures .The reinforced concrete flat slabs are an economical and popular structural system, however the use of this system is limited due to its susceptibility to shear failure One of the practical solutions used to increase the flat plate shear strength is to increase the concrete strength. In this research concrete characteristic strength up to 750 kg./cm2. 
In this investigation the focus will be on the effect of slab compressive strength (silica fume content), the effect of the reinforcement ratio and the effect of central square opening size on the behavior of the slabs, This goal is achieved through the studying the behavior of thirteen tested slabs. 
The experimental program was carried out on thirteen reinforced concrete plate of (120 x 120 x 7) cm. resting on four supports and subjected to concentrated load, The load was applied gradually in increments to record the first crack load and the failure load, beside the deflections and the strains at each load increment. 
Although it suffers more cracks than the normal strength concrete, high strength concrete has shown higher stiffness and less deflection Square opening of side length up to 10% of the slab side did not affect the load of the slabs.
