Comparative Study of CSA and LSA of RCC Building with External and Internal Floating Column Resting on RCC Transfer Girder

Abstract

Floating columns are very common these days and are adopted to increase the built up area on the floor. Floating columns are the structural vertical irregularities in buildings and is not desirable in seismically active areas in construction of building. This paper presents the comparative study of behaviour of RCC frame with floating column and is compared with construction sequential analysis. The crack width, short term and long term deflection due to creep and shrinkage calculations is also done on transfer girder in order to check for structural failure and is compared with LSA and CSA. The study includes the analysis of RCC frames structures with external and internal floating column resting on transfer girder. The analysis is done by using ETABS 2017 software. The outcome of this analysis will help to understand how the behaviour of structure’s response with construction sequence analysis and the effects on the member structure taken into consideration.
