Strength, stiffness and ductility of concrete-filled steel columns under axial compression [PDF]

, 2016
YesExtensive experimental and theoretical studies have been conducted on the compressive strength of concrete-filled steel tubular (CFST) columns, but little attention has been paid to their compressive stiffness and deformation capacity.

Research on Grouted Steel Pipe Supports Roof Cutting and Gob‐Side Entry Retaining Support Technology for Fully‐Mechanized Caving Face

Energy Science &Engineering, Volume 13, Issue 8, Page 3824-3839, August 2025.
ABSTRACT Aiming at the roof control challenges of gob‐side entry retaining in fully mechanized top‐coal caving faces, traditional concrete‐filled steel tube (CFST) support technology exhibits limitations such as slow strength development and complex construction equipment.

Reliability‐based assessment of a multilinear regression model for estimating the ultimate load of eccentrically loaded slender circular CFDST columns

Structural Concrete, Volume 26, Issue 4, Page 4621-4634, August 2025.
Abstract This paper presents a reliability‐based assessment of the multilinear regression (MR) model to predict the ultimate load of slender circular concrete‐filled double‐skin tubular (CFDST) columns under eccentric loading. To assess the MR model's performance, reliability analyses of 10 experimental CFDST columns are conducted and then compared to ...

Damage Detection of L-Shaped Concrete Filled Steel Tube (L-CFST) Columns under Cyclic Loading Using Embedded Piezoceramic Transducers

Sensors, 2018
L-shaped concrete filled steel tube (L-CFST) columns are used frequently in civil engineering, and the concrete damage inside the L-CFST column is difficult to monitor. This research aims to develop a new method to monitor the internal concrete damage in

Concrete-filled bimetallic tubes under axial compression [PDF]

, 2016
YesThis paper presents the experimental results of axial compression tests on concrete-filled bimetallic tubes (CFBT). The cross section of the bimetallic tube is composed of an outer layer made of stainless steel and an inner layer made of carbon steel.

Parameter priority of stub and slender rectangular CFDST columns subjected to eccentric loading

Structural Concrete, Volume 26, Issue 4, Page 4200-4214, August 2025.
Abstract This paper evaluates the behavior and ultimate load that previously identified parameters have on stub and long slender rectangular concrete‐filled double skin tubular (CFDST) columns subjected to eccentric loading. The investigation was performed using FE models that were calibrated and validated to eccentrically loaded experimental responses.

Multilinear regression model for predicting the ultimate load of slender circular CFDST columns subjected to concentric and eccentric loading

Structural Concrete, Volume 26, Issue 3, Page 3527-3545, June 2025.
Abstract This paper presents a novel approach to predict the ultimate load of slender circular concrete‐filled double skin tubular (CFDST) columns subjected to concentric and eccentric loading. The proposed approach was developed using a multilinear regression model through analyzing a database containing 165 CFDST column configurations.
