Title: EFFECT OF INFILL STIFFNESS ON SEISMIC PERFORMANCE OF MULTI-STOREY RC FRAMED BUILDINGS IN INDIA
Abstract: The typical multi-storey construction in India comprises reinforced concrete (RC) frames with brick masonry infills. Unreinforced masonry infill wall panels may not contribute towards resisting gravity loads, but contribute significantly, in terms of enhanced stiffness and strength under earthquake (or wind) induced lateral loading. However, in practice, the infill stiffness is commonly ignored in frame analysis, resulting in an under-estimation of stiffness and natural frequency. Also, the infills have energy dissipation characteristics that contribute to improved seismic resistance. It is instructive to study the implications of the common practice of ignoring the infill stiffness with regard to performance under seismic loading.
