Creep modeling for concrete-filled steel tubes
Journal of Constructional Steel Research, 2003Using the rate of flow method and the double power law function for basic creep of concrete, an algorithm is developed for the time-dependent behavior of concrete-filled steel tube (CFT), with or without the interface bond. The model adheres to geometric compatibility and static equilibrium, and considers the effects of sealed concrete, multi-axial ...

Owing to the excellent seismic resistance of circular concrete-filled steel tubes (CFST), no specific limitation on their in-service axial load level is provided in Chinese codes. Therefore, nonlinear creep could occur in Chinese CFST applications.

Behaviour and design of rubberised concrete filled steel tubes under combined loading conditions
Thin-walled structures, 2019Rubberised concrete has the benefit of utilising waste material, preventing resource extraction and improving concrete ductility, however at the cost of reduced strength and stiffness.

Flexural performance of concrete-encased concrete-filled steel tubes
Magazine of Concrete Research, 2014The flexural performance of concrete-encased concrete-filled steel tubes (CFSTs) was investigated. A finite-element analysis (FEA) model is developed to analyse the flexural behaviour of the composite member and a set of test data used to verify the FEA modelling.

Advances in Structural Engineering, 2019
This article investigates the behaviour of slender concrete-filled steel tube square columns strengthened by concrete-filled steel tube jacketing. The columns were realised by placing a square outer steel tube around the original slender concrete-filled steel tube column and pouring strengthening concrete into the gap between the inner and outer steel

Behavior of square hollow steel tubes and steel tubes filled with concrete
Thin-Walled Structures, 2007Abstract This paper investigates the occurrence of local buckling in bare steel and concrete-filled tubes to study how different depth-to-thickness ratios affect the response of the steel component. The experimental set-up and results of 24 tests are presented in this paper.

Improved Composite Effect of Square Concrete-Filled Steel Tubes with Diagonal Binding Ribs
Journal of Structural Engineering, 2019This paper proposes a scheme to improve the structural behavior of square concrete-filled steel tubular (CFST) columns, in which diagonal binding ribs are welded at all the four pairs of ad...

Review of strength behaviour of circular concrete filled steel tubes under monotonic pure bending
Journal of constructional steel research, 2019The existing literature concerning the flexural strength of circular concrete-filled steel tubes (CFSTs) has been reviewed in this paper. Using a much-expanded database of published flexural tests than considered in previous review studies, the ...
