In regions of medium to high seismic risk RC walls are typically added as lateral force resisting system and to increase the lateral stiffness and strength. Although slab-column connections possess low stiffness and do not contribute substantially to the lateral resistance of the structure, each connection must have the capacity to follow the seismically induced lateral displacements of the building while maintaining the capacity to transfer the vertical loads from the slab to the columns. Otherwise brittle punching failure of the slab occurs and the deformation capacity of the connection determines the deformation capacity of the entire building. This article presents an analytical model to account for the hysteretic behaviour and cumulative damage effects on the moment-rotation relationship of internal slab-column connections without transverse reinforcement when subjected to cyclic loading. The developed model is an extension of a mechanical model proposed earlier by the authors for monotonic loading conditions. The cyclic model assumes that a fixed shear crack governs the behaviour of the slab-column connection and adopts a hysteretic moment-curvature relationship for the radial direction. The main assumptions of the model are based on local deformation measurements from tests. Seismic damage is introduced through a non-cumulative model proposed by others. The model performance is assessed through comparison to tests performed by the authors. The cyclic model predictions are in good agreement with the experimental results and provide higher accuracy than the monotonic model with respect to both the local behaviour and the global behaviour.
