Punching shear failure is one of the main problems that need to be considered during the design of flat slabs especially at the critical slab column connection zone. This article is a part of a research program that is performed at the concrete research laboratory of the Faulty of Engineering, Cairo University to investigate the effect of the various types of shear reinforcement on the punching behavior of reinforced concrete flat slabs. In this paper, shearheads in the form of embedded steel beams were used to resist the punching stresses in flat slabs thus enhancing their performances. An experimental program was carried out using six half scale specimens of slab column connections having the same dimensions of 1100 mm x 1100 mm and 150 mm thickness and each was provided with a central square concrete column of 150 mm x 150 mm with 400 mm height. The main investigated parameters were the armlength, configuration and dimensions of the steel beams by using two different types: hot rolled and built-up sections. The experimental results showed that using embedded steel beams at the column-slab connection significantly improved the punching shear capacity and ductility of flat slabs. The test results were compared against values obtained using the provisions of the ACI international design code.
