BEHAVIOUR OF REINFORCED CONCRETE FRAME WITH IN-FILL WALLS UNDER SEISMIC LOADS USING ETABS

Reinforced concrete framed buildings with in-fills are usually analyzed as bare frame, without considering the strength and stiffness contributions of the in-fill s. However during wind and earthquake these infill walls contribute some response of the structure. Masonry Brick infill walls have been used in Reinforced concrete Frame structures as interior and exterior partition walls. Since they are usually considered as nonstructural elements their interaction with the bonding frame is ignored in the design. Infill substantially alters the behavior of the building subjected to lateral loads such as wind and earth quake forces. However when subjected to a strong lateral loads, infill panels t ends to interact with bonding frame and may induce a load resistance mechanism that is not accounted for the design.
