Title: Lateral Resistance of Partially Infilled Masonry Wall in Concrete Frame Structures | ||
Author: P. M. PRADHAN, P. L. PRADHAN, R. K. MASKEY | ||
Abstract: The analyses of infilled frame structures are generally done ignoring the presence of brick masonry in the analytical models. The real behavior of such buildings thus will vary during the earthquake events. Researches show that an infilled framed structure actually perform better against earthquake forces, however, when a structure is only partially infilled, the phenomena is again different. The lateral resisting capacity of infilled wall actually restricts the windward column only up to the wall height but above the wall height the free column deforms easily. In this paper, the resistance of partial infilled wall has been analyzed and it is concluded that if the wall height is reduced to less than 50 % of the clear frame height, the resistance increases significantly, thus allowing more shear in the windward column. The equivalent width of partial infill is also recommended. |
