Abstract
Infill walls are integral parts of any building including residential, commercial & industrial as well. These infill walls mostly serve purpose of room separators. For residential buildings these infill walls are required to maintain privacy of different rooms. The safety against fire is also one of the prime requirements of infill walls. In addition to these the infill walls also beneficial for thermal comfort, sound insulations, weather resistance, and durability & water-proofing. The thermal comfort is a requirement that the enclosure walls must comply. The infill walls should be durable, sound resistant, weatherproofed and waterproofed considering surrounding environment. There are large varieties of infills walls available in the market like brick infill walls, thin concrete infill walls, light weight AAC block infill walls. Timber infill walls, light weight still infill walls, glass infill walls (mostly used in commercial buildings) etc. However commonly used infill wall types are Brick, thin concrete and light weight AAC block infill walls. However various past studies have shown that the infill walls contribute majorly to the stiffness of building. This study is intended to understand the effect of various types of infill walls on structural behavior of the same building. The structural effects compared for the study includes modal behavior, deflections, drift, base shear etc. These results are also compared with building model without infill walls. Earthquake analysis method considered for this study is static coefficient method & Response Spectrum (dynamic analysis) method. IS 1893:2016 clause no. 7.9 gives provisions for RC framed Buildings with Unreinforced Masonry Infill walls, these provisions are also studied & applied in the dissertation. Results of actual infill models & without infill models are compared with infill walls modeled by using equivalent diagonal strut as per provisions of IS 1893:2016.
