The effect of applying loads sequentially is an important factor and should be considered whileanalyzingmultistoried frame structure. It is observed that the effect of the formationsequence increase with the increasein storeys is very important. Therefore, the effect of a construction sequencecannot be neglected and a preciseanalysis should be conducted.In this paper the construction sequential analysis has been studied on tube intube 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 sequenceis considered for dead load only. Also, the structure is analyzed for linear static analysis in order to check thestability of the structure as per Indian standards and then the structure is analyzed for constructionsequence analysis. The variation in Storey displacements, Column axial forces, bending moments andShearforces were compared to know the construction sequence analysis effect on tube in tube structural systembuilding.
