Abstract

Abstract

Reinforced concrete [RC] frame structure with masonry infill walls are being widely used for various purposes such as multi-storied residential, commercial, buildings in the earthquake-prone area. For partition and external walls of building infill walls or panels are commonly used to fill the gap between beam and column frame.The present study investigates the influence of the infill walls on the seismic performance of the high rise reinforced concrete building prone to lateral seismic loads. The study for different conditions is carried out with different infill materials like red brick masonry, AAC block masonry and fly ash brick masonry with different structural arrangements like the bare frame [BF], infill frame [IF], and wall panel frame [WF].The study is carried out for earthquake zone V. During an earthquake, infill acts as a compression strut which converts the load carrying mechanism from frame action to truss action. In the present study, infill effect introduced with the help of equivalent diagonal method according to IS1893:2016(Part 1).The analysis is performed with different methods of analysis like equivalent lateral force method and response spectrum method as per I.S1893:2016 using E-tabs® software. The parameters considered for comparison are base shear, storey displacement, storey drift and natural period.
