Role of Masonry Infill Wall on the Seismic Behaviour of Typical Ten Storey Building

Masonry infill walls are used as partition in reinforced concrete frames and are considered as a non-engineering structure for design and analysis purposes. The goal of this study is to compare different response parameters such as displacement, and bending moment and shear force in corner column of multi-storey RC frame structure with considering stiffness of infill wall and without considering stiffness of infill wall. For this purpose, a Ten-storey building is selected, which is supposed to be situated on Medium soil type and seismic zone III according to the IS 1893:2016. Openings are neglected in the building. Equivalent static method is used to check the behavior of building during earthquake using ETAB-2015. To find the width of compression struts IS 1893:2016 is used. The results are compared and shown in the form of graphs. It is concluded that the masonry infill walls may have significant effects on the seismic response of the reinforced concrete frame structures, therefore, stiffness of infill walls need to be considered during the design and analysis of the building.
