Abstract
Steel tubular construction has it efficiency because of the effective shape of cross-sections of load bearing members. Else more effective are thin-walled concrete filled steel tubes. The field of our research was on supper-thin and thin walled steel tubular columns, beam-columns, beams and trusses, their connections. The investigated steel tubular members were supplied with hollow concrete cores formed by centrifugal force. The fundamentals of behaviour and structural analysis with the substantiation of principles of design methods for members and connections are presented. The main attention is paid to projects in hollow concrete filled steel tubular structures, realized in various buildings proving their great technical and economical efficiency, safety and reliability.
