“…An innovative typology known as steel-reinforced concrete-filled tube (SR-CFST) is created by embedding a steel section within a CFST section. These composite columns can be improved both in terms of their combustion behavior and load-carrying capacity at room temperature [3]. However, because the steel tube and concrete core have different dilatation [4][5][6], there is a problem with the early elastic stage interface bonding that affects the elastic strength and stiffness of the CFST columns and results in significant drift in buildings throughout the service.…”

Several types of fibers have enhanced the structural response of reinforced concrete-filled steel tubes (CFSTs). This article presents a state-of-the-art review of studies done on the axial compressive behavior of steel and glass fiber-reinforced CFSTs. The aim of using fibers is to improve the response of the CFSTs. This research indicates the findings of experimental programs and analytical evaluations of the effects of the fiber incorporation on the behavior of the CFSTs. The results of this research work demonstrate that steel fibers (SFs) have enough evident improving effects on the failure mode and load-carrying capacity of the CFSTs. The SFs greatly increase the ductility of the CFSTs. To enhance the compressive strength and ductility of the CFSTs, adding the SFs by 1% to the concrete mix is more effective than adding by 1.5%. The use of the SFs mixed with expansion agent considerably increases the yield and ultimate loads of the CFSTs. More glass fiber-reinforced polymer (GFRP) sheets reduce buckling and develop the compressive strength of the CFSTs. The implementation of the GFRP jackets not only enhances the load-carrying capacity of the CFSTs, but also increases their ductility. The GFRP reinforcement techniques for the CFSTs are also effective in improving their structural stiffness and energy absorption capacity.

What does the general design method, described in EN 1994‐1‐1, mean in practice for the construction industry? Even though this method requires additional efforts, it provides improved design accuracy. High strength and high slenderness concrete filled steel tube composite columns with a solid steel core inside have undoubtable benefits. However, application of such columns requires the use of a general method of design and special knowledge not fully covered by Eurocodes.In order to utilize the general design method for ATLANT® Strong composite columns, Peikko has conducted an extensive development program. During the program, multiple tests were conducted on materials and the columns itself. The test results were used to calibrate models of Finite Element Analysis (ABAQUS), which allowed to investigate the behaviour of those columns even more extensively. Eventually, the general design method was implemented and calibrated, allowing reliable and optimized design.The paper contains an overview of ATLANT® Strong composite columns behaviour, the extensive testing program and calibration process to reach the optimal design of such columns. Additionally practical specifics, challenges and benefits are discussed.
