Abstract. The results of tests of eccentrically compressed concrete filled steel tube samples of square crosssection are presented in the article. It is shown that the presence of spiral reinforcement in eccentrically compressed concrete filled steel tube columns of square crosssection provide the significant increase of their bearing capacity.
Key words: concrete filled steel tube columns, eccentric compression, spiral reinforcement, bearing capacity.
