In the multi-storey R.C. frame buildings, brick masonry infill is common in practice. The analytical modelling of infill frame is a very complex. It shows a highly non-linear behaviour under the action of lateral forces. Also, the irregular distribution of infill in the building may cause the torsion or sway effect. This study's primary goal is to determine how these infill modelling methodologies affect the frame's overall reaction. Nonlinear static analysis is done and the infill is modelled as a single strut, double strut, shell element, etc. The various modelling approaches of infill are used in those building models. By comparing results, the suitability and accuracy of modelling method is examined. The effect of soft storey in building is also studied. This study demonstrates how the capacity of a building is increased by infill. The global behaviour of infill is satisfactorily represented by single strut method. The triple strut method is found to be explaining local failure of frames and frame-infill separation. The non-linear hinge formation pattern is also studied. The hinge formation pattern shows failure pattern of elements in frames.
