This paper gives a detailed presentation of a generic three-dimensional discrete-finite-element model that has been constructed for reinforced-concrete frames with masonry infill using ANSYS. Appropriate experimental data available from the literature are utilised to verify the model. The reasons behind some of previously observed damage to infill-frames are given. A simple method is proposed to overcome convergence issues which are related to the Newton-Raphson algorithm. It is shown that the model can be employed to predict the behaviour of the infill-frame over a wide range of drift, and to interpret its response at various stages of in-plane or out-of-plane loading.
