Abstract
The effect of applying loads sequentially is an important factor and should be considered whileanalyzing multistoried frame structure. It is observed that the effect of the formationsequence increase with the increase in storeys is very important. Therefore, the effect of a construction sequencecannot be neglected and a precise analysis should be conducted.In this paper the construction sequential analysis has been studied on tube in tube structure. For this purpose, a tube in tube structural system building with different heights (G+35, G+40, and G+45) has been considered forcomparative study. The plan dimensions of the building are 45 m x 72 m. The structures were modelled and analyzed by using ETABS finite element software.Construction sequence is considered for dead load only. Also, the structure is analyzed for linear static analysis in order to check the stability of the structure as per Indian standards and then the structure is analyzed for construction sequence analysis. The variation in Storey displacements, Column axial forces, bending moments andShear forces were compared to know the construction sequence analysis effect on tube in tube structural system building.
