Abstract

A double skinned composite tubular (DSCT) column, which is composed of two concentric steel tubes and concrete between them, was studied for its behavior under lateral loading. Quasi-static tests were performed by applying cyclic lateral loadings to two DSCT columns. One DSCT column had a flat inner tube (DSCT-FT) and the other had a corrugated inner tube (DSCT-CT). Test results were compared with those of a solid RC column and two hollow RC columns from other research. The compared two hollow RC columns had internal tubes and similar geometric and material properties with the DSCT columns. Test results showed that the DSCT columns had superior performance than other columns in terms of strength, yield energy, ultimate energy, and energy absorbing capacity. Owing to their superior moment capacities, the DSCT columns absorbed about 50% more energy than the solid RC column. However the DSCT columns showed lower energy ductility factors than the solid RC column because of their high yield energy.
