Inelastic Response of RC Moment Resisting Frames with URM Infills

Abstract

Brick masonry type of construction is found all over India and neighbouring countries like Nepal and Bangladesh. In India, these buildings are commonly found in North, extending from Punjab to West Bengal and Central India, from Haryana to Madhya Pradesh. These buildings are most commonly found in regions where good quality clay for brick production is abundantly available (World housing encyclopaedia report, 2003). But, past earthquakes witness major loss to brick masonry type of buildings. Many analytical and experimental studies have been done in past to understand the behaviour of brick masonry buildings during earthquake. Analytical study mainly includes, numerical modelling of the brick masonry buildings of type URM and Reinforced concrete Infill wall. In this work, primary focus is given to numerical modelling and nonlinear behaviour of brick masonry buildings subjected to lateral loads and understanding crack propagation in wall and calculation of quantitative damage to the building in terms of stiffness, ductility in load displacement curve.
