Concrete shear wall systems and flat plate slabs have been increasingly used in mid-and high-rise buildings in order to to resist lateral loading and, thus, permit a reduction in storey height. The resulting requirement for long-span flooring results in increased slab thickness of flat plates, with this increased slab stiffness having a significant effect on coupling beam behaviour. In the current study, slab effectiveness was investigated by subjecting large-scale, reinforced concrete coupling beams to cyclic loading and effects of slab stiffness on reinforced concrete coupling beams in flat plate systems, including failure mode, load-displacement, strength, stiffness, energy dissipation and effective slab width, were analysed.
