Abstract. The results of experimental research of precompressed and uncompressed concrete filled steel tube elements with core reinforcement of a concrete core with hightensile reinforcement are described and analyzed in the article. The possibility of using hightensile reinforcement is provided in such structures due to the high deformability of the concrete core, and this contributes to an increase in the bearing capacity of concrete filled steel tube elements.
Key words: concrete filled steel tube columns, hightensile reinforcement, concrete core, steel shell, experimental researches, precompression, bearing capacity.
