Abstract
Increasing incidents of failure of structures during the creation phase is a rising concern in India. The failure of various structural elements like slabs, beams, columns, and shear walls is significant. While analyzing a multi storey building frame, conventionally all the probable loads are applied after modelling the entire building frame. But in practice the frame is constructed in various stages. Accordingly, the stability of frame varies at every construction stage. Even during construction freshly placed concrete floor is supported by previously cast floor by formwork. Construction sequence analysis (CSA) helps in analysing the building in a new manner. The aim of this study is to investigate the change in values of numerous structural parameters namely axial force, shear force, and bending moment during and after construction and after a life of 50 years with creep effect. Using construction sequence analysis, this study analysed the behaviour of structural parameters of a G+10 storied building located in low prone earthquake zone with floating columns resting on transfer girder and measured these results against the response spectrum analysis of the building. In previous studies, the values of deflection and shear forces found in CSA are more than dynamic analysis. This study gives an idea regarding the failure of buildings during the construction phase. The present study provides a comparison of conventional analysis with construction stage analysis for RC building after the construction and the life of 50 years using ETABS software.
