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 ...

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.

Machine Learning for Predicting Required Cross-Sectional Dimensions of Circular Concrete-Filled Steel Tubular Columns

Buildings
Machine learning methods are widely used to predict the bearing capacity of concrete-filled steel tubular (CFST) columns. However, in addition to this task, the engineer often faces the inverse problem: to determine what cross-section dimensions of the ...

Improving interface bonding of double-skinned CFST columns [PDF]

Magazine of Concrete Research, 2013
It has been demonstrated that high-strength concrete (HSC) is able to improve the strength-to-weight ratio of reinforced concrete columns and maximise the usable areas of tall buildings. However, closely spaced transverse reinforcement needs to be installed to provide stronger confinement for averting brittle failure of HSC.

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.

Structural performance of split orthogonal beam joints in continuous beam‐type circular concrete‐filled steel tubular beam‐to‐column connections

JAPAN ARCHITECTURAL REVIEW, Volume 8, Issue 1, January–December 2025.
In this study, joint details for a split beam orthogonal to a continuous beam in concrete‐filled steel tubular beam‐to‐column connections were tested. The basic joint performance and stress transfer mechanisms were examined using finite element analysis. Abstract A continuous beam‐type connection has been proposed as a new type of concrete‐filled steel
