Abstract

In our country population growth increses day by day, increase in the land costs to satisfy large population specially in urban cities have made a door for construction of tall buildings. To economize land area, building height increased & the construction of reinforced cement concrete structure increases, during which shortening of column is reported which is become more significant with increase in height and impact the strength design and serviceability of the building. If column shortening is not addressed properly, it can impact the serviceability of the building as it impact on structural and non structural elements. So study of shortening of column in tall structure is importanat. In this paper the effect of column shortening in tall structure, in post construction stage analysis in which all loads applied in a single step, construction stage analysis and construction stage with time dependent effect analysis in which dead load, live load are released on building gradually as the construction progresses is carried on different strucutural system like frame, frame-shear wall and tube in tube system using ETABS software. In the analysis dead load, live load, lateral load due to wind load, earthquake load should be considered. The result obtained from this study gives idea about effect of column shortening in different method of analysis with different structural system and varying height of the structure.
