ABSTRACT
During analysis of a building structure, normally after complete modelling full loads are applied on entire building frame and linear static analysis is done. But in actual practice the dead load due to each structural element is applied in various construction stages of each story of the building structure due to the material nonlinearity behaviour. The loads considered in linear static analysis change in transitory situation and hence the outcomes will not be suitable and satisfactory. Therefore the building structure should be analysed at every stage of construction taking into account the load variations. A tall building is defined as one in which the structural system is adopted such that to make it sufficiently economical and also to resist lateral forces due to wind or earthquakes within the prescribed criteria for strength, drift and comfort of the occupants.
