Coupled shear walls effectively maintain the lateral stability of buildings under both wind and earthquake loading. Of late, the slab thickness within flat plate systems has increased dramatically, with steel-reinforced concrete coupling beams now frequently employed in coupled shear wall systems. This paper studied the effect of slab stiffness on steel-reinforced concrete coupling beam behaviour within flat plate structural systems in the context of failure mode, load-displacement, strength, stiffness, energy dissipation and effective slab width. Results indicate that steel-reinforced concrete coupling beam with 100 mm slab thickness exhibited increased strength (130%), increased initial stiffness (120%) and increased accumulated total energy dissipation (129%) when compared with steel-reinforced concrete coupling beams comprising no slab.
