New shear transfer system for concrete‐filled steel tube (CFST) columns

Steel Construction, 2022
AbstractConcrete‐filled steel tube (CFST) columns are frequently used in construction due to their high ductility and improved loadbearing capacities. At beam‐to‐CFST column joints, gusset plates are welded to the outer face of the steel tube, and specific elements should ensure the shear transfer between the inner face of the steel tube and the ...

Behavior of prestressed concrete-filled steel tube (CFST) beam

Engineering Structures, 2016
Abstract Concrete-filled steel tube (CFST) member is widely used for building, bridge and foundation structures because of its excellent performance. When a CFST member is subjected to axial loads, the filling concrete is confined by the steel tube, resulting in a tri-axial state of compression that improves its strength, stiffness and ductility ...

Flexural strength evaluation of concrete-filled steel tube (CFST) composite girder

Journal of Constructional Steel Research, 2018
Abstract The flexural strength of the concrete-filled steel tube (CFST) composite girder was investigated in this study. Firstly, simple equations to evaluate the flexural strength of the CFST composite girder under both positive and negative bending moment were derived based on the plastic stress distribution method (PSDM).

Concrete filled steel tube (CFST) columns subjected to concentrically partial compression

Thin-Walled Structures, 2012
This paper studies the behaviour of thin-walled concrete filled steel tube (CFST) column subjected to concentrically partial compression. A series of tests was carried out to investigate the effects of sectional type, length-to-diameter (width) ratio, partial compression area ratio and top endplate thickness on the behaviour and bearing capacity of ...

Behaviors of axially loaded square concrete-filled steel tube (CFST) Stub columns with notch in steel tube

Thin-Walled Structures, 2017
Abstract Compressive tests of the CFST stub columns with artificial notches in the steel tubes were conducted in this paper to investigate the effects of the material imperfections of steel tubes on column performances. The load-strain responses, column strength and confining effects were discussed in detail.

The prediction of fire performance of concrete-filled steel tubes (CFST) using artificial neural network

Thin-Walled Structures, 2021
Abstract Search for enhancing the efficiency has led to composite structures such as concrete-filled steel tubes (CFST) with increasing applications across the world. The fire performance of CFST columns needs to be understood comprehensively. In this paper, the effectiveness of the most important parameters on fire resistance rating (FRR) and ...
