Coupled shear wall buildings are popular form of high rise structures. Flexural behaviour of floor slab acting as coupling beam is very important for the analysis of such structures. Recent advancement in the new generation of high performance concrete materials provides an alternative to conventional concrete to enhance the performance of coupling slabs. This paper presents the flexural behaviour of coupling slabs incorporating engineered cementitious composite (ECC) as an alternative to conventional concrete. ECC is a unique type of fibre reinforced cementitious materials with ultra high ductility. The high strain capacity while maintaining low crack widths makes ECC an ideal material for the coupling slab application. The non-linear coupling action of ECC link slabs is investigated experimentally with small-scale model specimens under monotonic loading. The ECC coupling slab performance is compared with conventional self-consolidating concrete (SCC) based on load-displacement/moment-rotation response, flexural stiffness, deflection capacity enhancement, crack control characteristics and failure modes.
