Abstract
In recent times, many buildings are planned and constructed with architectural complexities. The complexities include various types of irregularities like floating columns at various level and locations. These floating columns are highly disadvantageous in building built in seismically active areas. The earthquake forces that are developed at different floor levels in building need to be carried down along the height to ground by shortest path, but due to floating column there is discontinuity in the load transfer path which results in poor performance of building. Building structures are analyzed in a single step using linear static analysis (LSA) on the assumption that the structures are subjected to full load at once the whole structure is constructed completely. In reality the dead load due to the each structural components and finishing items are imposed in separate stages as the structures are constructed storey by storey for nonlinear behavior of material hence construction sequence analysis (CSA) is carried out.The analysis of the model is carried out with the help of ETABS software. It involves two types of analysis such as LSA and CSA, which is carried out on RC building structure of G+ 5 storeys with floating column in exterior position where the RC transfer girder is replaced by composite transfer girder and the parameter such as beam moments and deflection are compared.
