A typical reinforced concrete coupling beam connects shear walls. The concrete beam section incorporates continuous longitudinal reinforcement designated as REINF HEF and REINF a, combined with transverse stirrups S1. Embed plates with specified development lengths Lt are anchored into the adjacent concrete walls at each end of the beam. Two-inch typical clearances and depth dimensions govern the overall geometry of the reinforcement cage.
