dc.description.abstractReinforced concrete (RC) frame buildings with unreinforced masonry infills are widely used in developing countries with high seismicity. Even though the presence of infills has a significant influence in enhancing the strength, stiffness and energy dissipation, these are frequently neglected in the seismic design calculations. The increase in lateral stiffness of infilled frames leads to attract larger forces, and the confining columns should have sufficient capacity to resist the increase in shear demand near the contact zones with infill. This local adverse effect of infill is more pronounced in ground storey columns leading to collapse of the entire structure, especially where one-sided imbalanced contact exists between columns and infill. Therefore, the primary objective of the present study was to investigate the effect of infill on shear demand and failure of columns, and develop methodologies to prevent or delay the shear failure of columns. Prior to the development of methodologies, it is important to understand the modelling and design requirements of current earthquake standards concerning the design of masonry infilled RC frames. At the same time, the realistic evaluation of shear failure of columns requires suitable material and analytical models. To develop a nonlinear material model, a detailed material characterisation needs to be carried out, as most of the times the nonlinear properties of masonry significantly vary due to their composite nature and geographical dependency.en_US
