Behaviour of rectangular concrete-filled steel tubular

2021-6-1  Concrete-filled steel tubular (CFST) columns are gifted with properties such as high strength, high ductility and large energy absorption capacity, which lead to extensive applications in high-rise buildings, large-span bridges and other types of structures. Besides, CFST columns can be constructed conveniently without formworks.

Push-Out Behavior of Rectangular Concrete-Filled

2000-10-1  A series of push-out tests of rectangular concrete-filled tubular columns (CFT) was recently conducted. The objective of this research program was to identify the shear transfer mechanisms between the infilled concrete and the steel tube and to determine a method for evaluating the capacity of the steel-concrete interface in a CFT column.

Behaviour of eccentrically loaded high-strength

2006-8-1  The advantages of CFT columns can be attributed to the composite action between the steel tube and the concrete infill. The steel tube works not only as longitudinal reinforcing bars to resist the loads but also as ties or spirals to confine the concrete infill. Therefore, both strength and ductility of the concrete are enhanced.

Study and Buckling Analysis of Concrete Filled Steel

2018-12-27  The structural behavior of the concrete filled steel tube is affected by the Poisson’s ratio of both steel and concrete. At the initial stage of loading, Poisson’s ratio of the concrete is lower than that of steel. Hence the steel tube does not contribute confining effect to the concrete.
