Abstract – The scarcity of land and mammoth population increase have given impetus to multistoried structures as well as steering the engineers to consider realistic design approaches. Conventionally, multistoried buildings are analyzed based on the fundamental assumption that all the loads act on a structure simultaneously post the complete construction of structure. Thus, we analyze the structure with linear static analysis approach and that too in a single step. However, this methodology does not model the actual construction practices. Moreover, the structural behavior in linear static analysis is different from the reality as reduction in stiffness and cracking, deformations, moment redistributions, etc. occur in the structure transiently in various stages of the construction. Present study considers the nonlinear behavior of structures into account and incorporates the story-by-story construction using Sequential Construction Analysis in three illustrative RCC buildings. The study aims at understanding the responses of building elements namely bending moments, axial forces and axial displacements of building elements. Further, the geometric non-linearity in terms of P-delta effect is considered and the structural responses are compared with the Sequential Construction Analysis and Linear Static Analysis.

Keywords – Story-by-story construction; Linear Static Analysis; Sequential construction; P-delta effect; non-linearity
