COMPRESSIVE STRENGTH AND DEFORMATION CAPACITY OF CONCRETE-FILLED TUBULAR STUB-COLUMNS : Strength and Rotation Capactity of Concrete-filled Tubular Columns, Part 1

Abstract

With respect to the compressive behaviour of concrete-filled tubular steel stub-columns, the effect of confinement of inner concrete by steel tube wall are evaluated on the basis of experimental data hitherto obtained. The predicting formulae of maximum compressive strength of concrete-filled tubular steel stub-columns are derived taking the effect of confinement of concrete into consideration. It is demonstrated that the correlation between the predictions and test resultus are satisfactory.
