However, nowadays different innovative and environment-friendly infill materials that can be used in place of bricks are gaining more popularity day by day. i.e., AAC Blocks. Traditionally, since masonry is a non-structural element its influence in a building under seismic loading is often neglected but some studies have shown that infill wall panels play a significant role in the case of earthquakes. In order to assess the effect of brick and AAC infill walls, the seismic behaviour of a hypothetical G+6 storey RC building is studied. Here, the seismic analysis is carried out by response spectrum analysis, and infill walls are modelled using the equivalent diagonal strut method. Structural Engineering software CSI ETABS (Extended3D Analysis of building System) Version:18.0.2 is used. Primary objective of this study is to compare the results of Storey displacement, storey drifts, bending moments, axial and shear force to find out how much cost can be saved by considering the infill influence under the seismic forces and how effective AAC blocks are compared to conventional clay brick.Articlehttps://www.researchgate.net/publication/353174828_Comparative_Study_of_Brick_Infill_Wall_and_Autoclaved_Aerated_Concrete_AAC_Blocks_Using_Response_Spectrum_Analysis
