Abstract

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.
