Abstract

This paper addresses axial shortening prediction o f the vertical concrete elements of tall buildings with a particular focus on developing a reliable mo del for high strength concrete (HSC). An establishe d reinforced concrete column shortening model used fo r normal strength concrete (NSC) is modified to pre dict axial shortening in vertical elements made of HSC. To compare with the theoretical model, the axial sh ortening measurements taken from the 83 storey World Tower B uilding, Sydney (WTS), obtained during the construction period, are used. The theoretical mode l having the best match with the actual measurement s are recommended for predicting axial shortening of vert ical elements using HSC.
