Abstract
Reinforced concrete coupled shear walls in tall buildings have been commonly employed as the main lateral-resisting elements to resist high stresses resulting from lateral loads. They should behave with high shear strength, stiffness, ductility, and energy dissipation capacity without collapsing under high lateral loads. A new type of coupling beam that connects two shear walls is the plate-reinforced concrete (PRC) coupling beam which is employed to resist high-induced shear forces due to its high shear capacity and ductility.
The design of PRC coupling beams in the different international design codes like ACI, Eurocode, and ECP, primarily depends on mechanical models that rely on the strength superposition concept that ignores the composite action of the PRC beams. However, another approach proposed by Su and Lam (2009), emphasizes the moment-shear (M-V) interaction.
In this study, a finite element model that simulates the behavior of PRC coupling beams was created and verified using experimental specimens of Tian et al. (2019). The model was used to assess the design approach suggested by Su and Lam (2009) and compare it with both American and Egyptian design standards. The results aid in developing safer and more effective PRC coupling beam designs for tall buildings.
