Abstract

While analyzing a multi-Storied RCC frame buildings, conventionally all the probable loads are applied after modeling the entire building frame. But in practices of RCC frame structures it is constructed in various stages. According to the stability of RCC frame varies at each construction stage. Even during RCC construction freshly placed concrete floor is supported on previously casted floor by formwork. Thus, the loads assumed in traditional analysis will vary in transient situation. Obviously, results obtained by the conventional analysis will be unsuitable. Therefore, the frame should be analysis at every construction stage taking into consideration variation in loads. The phenomenon known as Construction Stage Analysis considers these uncertainties precisely. Construction stage analysis revealed more criticality of the structural component during construction stage due to additional forces, which must be considered during designing and analysis phase of the high rise building. Hence, it is advisable to analyze the structure with construction stage analysis.
