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.

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

Ultimate Flexural Strength of Circular Concrete‐Filled Steel Tubular Beam‐Columns Considering Stress Gradient and Scale Effect

JAPAN ARCHITECTURAL REVIEW, Volume 8, Issue 1, January–December 2025.
In this study, an evaluation method is proposed for calculating the ultimate flexural strength of CFST beam‐columns, incorporating the stress gradient, extreme compression fiber strain of concrete, and scale effect of concrete. Additionally, the appropriate strain at the extreme compression fiber of concrete necessary for accurate strength prediction ...
