This document reviews research on analyzing reinforced concrete (RC) frame structures with fully, partially, and no masonry infill walls in different seismic zones of India. It discusses how infill walls can increase structural strength, stiffness, and seismic resistance by interacting with the RC frame. The document summarizes several studies that found infill walls reduce displacements, drifts, and bending moments in frames while increasing base shear and axial column forces. It proposes analyzing an RC frame building with and without infill walls using the STAAD PRO software to understand how infill walls affect seismic response. The methodology section outlines steps for modeling the structure and applying loads and seismic analysis.
