A Comparative Studyof Construction Sequence with Conventional Analysis
Main Article Content
Abstract
Rising incidents of failure of buildings during the construction phase is an
increasing concern in India. The failure of structural elements like slabs, beams, columns,
and shear walls is critical. Construction sequence analysis (CSA) helps in analysing the
building in a staged fashion. Despite its importance, our knowledge of CSA is poor, and the
implementation is imperfect. The purpose 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. Using CSA, this study analysed the values of structural
parameters of a 15 storied building located in Pune and measured these results against the
dynamic analysis of the building. The values of deflection and shear forces found in CSA are
up to 45% more than dynamic analysis. This study definitively answers the question
regarding the failure of buildings during the construction phase and how it can be avoided by
using CSA. Experimental studies are needed to establish real-world values of structural
parameters.
