Study on a Layered Finite Element Method for Hollow Concrete‐Filled Steel Tube Columns
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Concrete‐filled steel tube (CFST) structures are widely applied in modern engineering due to their high strength, stiffness, and ductility. However, hollow CFST (H‐CFST) columns exhibit distinct mechanical behavior because of the incomplete filling of concrete and the radial variation of confinement provided by the steel tube, which limits the ...

Numerical Approach for a Partial CFST Column using an Improved Bond-Slip Model
, 2020 본 논문에서는 부분 CFST (concrete-filled steel tube) 기둥에 대한 수치해석적 저항력 평가 방법에 대해 소개하고 있다. 기존 RC (reinforced concrete) 기둥에서 소성힌지가 발생할 것으로 예상되는 부분을 강관으로 보강함으로써 완전 CFST 기둥보다는 적은 재료를 사용하여 비슷한 휨 모멘트 저항력을 가지는 부분 CFST 기둥의 디자인 컨셉을 제시하였다.

Effect of structural damage on the thermal response of CFST columns
, 2023 Concrete-filled steel tubular (CFST) members are efficient structural members which are currently increasingly used in the construction industry. Under multi-hazard loading conditions, columns are often subjected to structural damage followed by thermal loading due to fire. This article studies the effect of mechanical damage on the thermal response of
