Seismic Evaluation of RC Unsymmetrical Building with Floating Columns Soft storey Considering Different Configuration
Open first story and Floating columns are typical features in the modern multi storey constructions in urban India.This paper deals with the study of architectural drawing and the framing drawing of the building having Floating columns Soft storey. Existing commercial building comprising of G+ 7 structures has been selected for carrying out the project work. The building was modelled as per plan and the plan was remodified in different ways so that total twelve models are carried out in this study.In the present work, the recommendations such as the effect of Infill, Bracings and Shear wall are introduced in the building in order to improve the seismic performance.The structural action of masonry infill panels have been taken into account by modelling them as diagonal struts.Equivalent static and response spectrum methods are used for analysis by ETABS 15.2.0 software. The structure was assumed to be situated in earthquake Zone III V on a medium soil (type II) The parameters evaluated were displacement, storey drift, storey shear, and storey stiffness of all models are compared and significant co relationship between these values are established with graphs.
