Behaviour of RCC Building with Transfer Floor System under Earthquake Loading

Abstract

Now a days building is constructed for mixed use like residential, commercial, parking etc. Transfer girder system is one of the way to provide large space at bottom stories and fulfil this requirement. In transfer floor system heavy load from top storey is transferred by transfer plate, transfer girder and largely spaced columns. Transfer floor system can be used for framed building as well as building with shear wall. As transfer floor system develops mass irregularity at transfer level, its behaviour under seismic load must be investigated. In this paper two case studies are conducted and seismic parameters are calculated. 3D finite element model is used for analysis. In one case study, analysis of moment resisting framed building is done with and without transfer floor system. In second case study building with shear wall is considered for analysis with and without transfer floor system. Equivalent static method is considered for analysis as per codal provision. Comparative study of seismic parameters like base shear, storey drift and storey displacement are done for different finite element models.
