Abstract
Abstract- Shear reinforcement systems contribute in enhancing the punching shear strength of reinforced concrete slab-column connections. An experimental study has been conducted to investigate the efficiency of using headed shear studs to improve the strength and ductility of slab-column connections subjected to punching shear. The study involved seven reinforced concrete two-way slab specimens having plan dimensions of 1100mm×1100mm, which were experimentally tested under square patch loading. The considered parameters were the spacing, orientation and layout arrangement of the shear studs. The study showed that the punching shear strength of specimens with headed shear studs was improved by up to 37.2% compared with that of a control specimen without shear reinforcement. The strength increase recorded for specimens with stud spacing of 65mm was in average 16% more than that for specimens with stud spacing of 90mm. Also, shear studs improved the ductility of the studied specimens particularly those with radial arrangement of studs. It was generally concluded that radial arrangement of shear studs outperformed orthogonal arrangement as far as the strength and ductility were concerned
