Objectives/methodology: In this study, a four-story frame structure is modelled using finite element software in two different conditions of infill and without infill masonry effects. A pushover analysis is carried out to assess the seismic response and building performance under three different loading conditions of modal, triangular, and uniform loading. The all-possible loadings in negative and positive directions have been applied and building response is measured. A performance capacity curve in terms of base shear is developed for all possible loading scenarios. Finally, a comparison of bare and infill frame has been made and some conclusions were made.
Findings/ application: Uniform loading among all three categories is found to be higher in capacity for both types of frames in positive and negative directions. The presence of non-structural masonry walls results in a better behavior of frames compared to bare frame. They initially increase the strength, stiffness, and energy dissipation of frames despite their brittle failure.
Keywords: Building Capacity Curve, Performance Point, Infill Frame, Pushover Analysis.
