ANALYTICAL STUDY ON BEHAVIOUR AND PERFORMANCE OF INFILLED FRAME STRUCTURE WITH REINFORCED ECCENTRIC OPENING

This numerical analysis has discussed the behaviour of frame structure with eccentric infill wall opening modelled shell and strut elements. In beginning, validation models were created by following laboratory tests results. Then, a simple one-storey an was varying ratios taking angle formed to obtain equation for width that corresponds element model angles variation. The then applied 3-storey structures. comparison between investigated linear nonlinear static analysis. openings (Weo) is determined modifying stiffness coefficient (Ce) based on ratio. application Weo showed had comparable model. drift ratio smaller angle, greater stiffness. pushover shows infilled able withstand larger base shear force than open
