Paper Details

Axial shortening of columns due to long term creep and shrinkage is unavoidable in reinforced concretebuilding. However, calculation of exact value of axial shortening is not an easy task since it depends on a number ofparameters such as the type of concrete, dimension of member, volume to surface ratio, reinforcement ratio, and the rateof construction stage. All these parameters may or may not be available to the design engineer at the preliminary designstage of construction. Furthermore, long term Axial shortening of columns could affect the horizontal structuralmembers such as beams and floors and hence could affect the plaster, cladding and partitions. This paper presents a setof guidelines so that the effect could be considered approximately, especially at the preliminary design stage and alsoduring the construction phase. In this study it is assumed, construction stage analysis considers the creep and shrinkageeffects of a 35-story building consist of an exterior concrete frame and interior shear walls. The displacements of verticalmembers are evaluated by CEB FIP MC2010 and ACI209R. Also, Axial shortening compare by both method at differentconcrete age (Time dependent effect)
