An experimental investigation of seismic behaviour of identical beam-column subassemblies was conducted by testing two half-scale joint models: one without a slab and the other with a slab. A qualitative model simulating participation of the floor slab was developed by establishing the slab crack patterns (yield lines) and the state of strain in slab bars. Based on the verification results, it was concluded that the joint model improves prediction of seismic behaviour, and that this model allows explicit evaluation of the slab effect on the joint.
