Prediction of column shortening due to creep and shrinkage in tall buildings

Axial shortening due to creep and shrinkage in tall buildings should be taken into consideration. When different types of structure such as steel columns and reinforced concrete shear walls are used together, vertical displacements resulted from accumulation of the axial shortening may become unequal, and cause floor inclination. This paper describes a prediction of axial shortening of a 300m-high model structure by visco-elastic analysis.
