Design recommendations for reinforced concrete beam-column connections are based on limited experimental studies on the seismic behavior of eccentric connections. To supplement existing information, an experimental study was conducted that focused on the affect of eccentricity of spandrel beams with respect to the column. Specimens included a floor slab and transverse beams to evaluate the effect of slab participation. Test results indicated that including the floor system significantly reduced the negative influence of eccentricity. It was observed that damage was reduced, specimens had fuller load-versus-drift hysteresis loops with high energy dissipation capacities, and deterioration of joint shear stiffness and strength were delayed. Moreover the joint shear stresses resisted by the connections, without major damage, were higher than current design values. This was due to the participation of a larger area of the joint, region in resisting shear which indicates that "Recommendations for Design of Beam-Column Connections in Monolithic Reinforced Concrete Structures (ACI 352R-02)" (Joint ACI-ASCE Committee 352) recommendations for effective joint width are conservative.
