Axial Compression Performance of Concrete-Filled Steel Tubular Columns with Different D/t Ratios
Advances in Materials Science and Engineering, 2022 The impacts of three diameter/thickness (D/t) ratios (21.22, 25.46, and 31.83) and concrete strengths (40 N/mm2, 50 N/mm2, and 60 N/mm2) on the strength capabilities of concrete-filled steel tubular (CFST) columns are investigated in this study.

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 ...

A New Method for Predicting the UL of Circular CFST Columns
Open Journal of Civil Engineering, 2013 Concrete filled steel tube structures have gained booming development in recent decades, especially in China. Simplified methods have been proposed in design codes, such as the Eurocode 4 (EC4) and the China engineering and construction specification (CECS). In EC4, the confinement effect is reasonably related to slenderness and load eccentricity.

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.To tackle the issue of relying solely on one research approach and the inadequate examination of the elements influencing the soil plug effect during the penetration of pipe piles, this study combines experimental modeling with numerical simulations. Through these approaches, we explore the formation and progression of the soil plug, delving into its ...
