Axial shortening in an 80-storey concrete building

An 80-storey reinforced concrete building located on the Gold Coast was instrumented to monitor axial shortening behavior in load-bearing elements. Axial shortening of selected columns and core walls across a number of levels were taken up to 3 year duration, from initial construction period to the completion of the structure with full service loads applied. This paper presents an extensive set of measurements of selected basement columns. Comparisons of columns between basement levels, as well as symmetrically related and adjacent columns, are made
