One of the most potential adverse effects of infill is that it may shear off weak columns, specifically ground storey exterior columns where shear force demand is higher in addition to the effect of infill. Therefore, determination of shear demand on columns due to the detrimental effect of infill is of primary importance for proper design that results in ductile flexural failure. In the current study, macro-modeling technique using equivalent diagonal strut was improved to capture the component (shear) failure as well the global response of the structure. The analytical model was calibrated from the experimental results of bare frame and infilled frame carried out by the authors. To validate the proposed modeling technique, masonry infilled frames from the past experimental studies were chosen and non-linear pushover analyses were carried out. From the results, it was observed that the improved modelling technique can be successfully used to predict the shear failure of RC columns, and hence, can be used in evaluating the realistic shear demand on RC columns.
