Abstract: In this paper, a new connection system for reinforced concrete walls and floor slabs is proposed. This connection system includes the provision of additional shear reinforcement within the joint region of the wall and the slab. Stirrups were coupled with the main bars throughout the length of the concrete joint core in the connection region. Reversed cyclic loading tests on two wall-slab connection specimens were conducted to observe the efficacy of the proposed system of connection. The test results demonstrated effectual confinement of the core, greater energy dissipation capacity and ductility of the connection region due to the addition of the stirrups. As a potential connection system for the wall and slab joint region with enhanced energy dissipation capacity, it can be practiced in seismic prospected areas during the construction of reinforced concrete shear wall structures.

Keywords: wall and slab joint; connection system; reverse cyclic loading; energy dissipation; ductility.
