Steel coupling beam (SCB) is a substantial member of the hybrid coupled walls system. When coupled walls are linked by SCB rather than conventionally reinforced or diagonally reinforced coupling beams, the system's strength and energy dissipation capacities are greatly enhanced.F-Series six beam couplings are ideal for light duty power transmission applications such as coupling a servo motor to a lead screw in a motion control system. These flexible couplings feature larger body size and stronger beams to provide high torque capacity and low windup, while not sacrificing misalignment capabilities. In ductility-based seismic design, the coupling beam is the main energy dissipator in reinforced concrete (RC) frame-shear wall. Before the wall limbs are damaged, the coupling beam yields and consumes most of the energy.
