Abstract: Since long Masonry Infills (MI) are being used to fill the voids between the horizontal and the vertical structural elements such as beams and columns. They are treated as non-structural elements and they are not considered during the analysis and design of the structure. But, when Laterally loaded, the MI tends to interact with the RC frame, changing the structural behavior. Here, in this study, an attempt is being made to incorporate the MI in the form an Equivalent Diagonal Strut (EDS), whose width is calculated using the various relations proposed by the researchers. A general review of the relations proposed by the Researchers in calculating the width of the EDS is being made and compared. The paper also focuses to study the variation in the Deflection and the Stiffness in the frame by modeling the MI as EDS and performing the linear analysis. The software being used for the analysis is ANSYS.
