Behaviour of Concrete Filled Steel Tube CFST Subjected to Shear A Review

Concrete filled steel tubes represent common structural members for modern civil engineering projects such as high rise buildings under shear and axial loads. Because of excellent composite functional characteristics, the axial load carrying capacity of concrete increases due to ductility and confinement provided by the steel tube. Shear behavior is one of the most important CFSTs that ensures the integrity of members and the whole structure. The paper first provides a database including CFST shear experiments and then exploits this database to present a global review of the shear behavior of CFSTs. The paper tries to analyze the available literature on the shear behavior of CFSTs. Special attention will be paid to the circular and rectangular hollow types of CFST, which, in view of their importance, have not been given enough attention in information sources. This study examines some of the critical parameters affecting the ultimate shear strength of CFST members such as material properties, geometrical configurations, and composite action between steel tube and concrete fill. The presented research also adds to the understanding of CFST shear performance, besides providing design expressions related to the contribution of individual steel and concrete. These research outcomes contribute to the development of safe and efficient applications of CFST in structural engineering.
