In reinforced conventional concrete tall buildings, especially in the lower stories of beam---column connections, concrete casting and vibrating is a big problem, often due to reinforcement congestion. A good alternative for conventional concrete is to use a new concrete generation called Self Compacting Concrete (SCC). With its high fluidity and no need of inner or outer vibration, it offers both quality and cost improvement over conventional concrete. To achieve acceptance for the use of SCC in reinforced concrete in RC beam-column connections, the available results of experimental research conducted on three reinforced SCC specimens, with different percentages of $\rho$ and $\rho'$, were used, to determine the ductility and concentrated plastic rotation developed in the connections. The simulated beam-column connections were loaded incrementally, using a point load, and the vertical deflection, tensile steel and compressive concrete strain were measured at different sections up to failure.In the theoretical phase of this investigation, a 3-D model i.e., ANSYS nonlinear software, was used and the load-deflection and plastic hinge developed were plotted. A comparison of the experimental and theoretical results of the member was performed and it was shown that a reasonably good agreement is available. As a general conclusion, it is possible to design RC ductile connections made of SCC.
