Tensile Behavior of Concrete‐Filled Steel Tubular Column Splices Using Perforated Steel Plates

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
This study proposes a CFST column splice design transferring stress through infilled concrete using welded perforated steel plates. Pull‐out tests on the perforated steel plates were conducted to develop a strength prediction formula, which was validated through tensile experiments on column splices and predicted their tensile capacity.

Study on the Joint Performance of Concrete‐Filled Steel Tubular Columns With Unequal Depths Above and Below the Diaphragm Plate

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
This study investigated the seismic behavior and stress transfer mechanisms of through‐diaphragm beam‐to‐column connections of CFST columns with different upper and lower sizes. An ultimate strength formula based on yield‐line theory that incorporates concrete bearing resistance is proposed, and its predictions agree well with the experimental results.

Load Rating and Buckling of Circular Concrete-Filled Steel Tube (CFST): Simulation and Experiment

IOP Conference Series: Materials Science and Engineering, 2018
The paper studies estimate ultimate strength and local buckling of circular concrete filled steel tube (CFST) specimens subjected to axial load using strain gage, force transducer and displacement sensor. The strain responses of CFST column in testing procedure and the results of finite element modelling will be used to predict failure modes when ...

Stub Column Tests on Concrete‐Filled Wire Arc Additively Manufactured Steel Tubes

ce/papers, Volume 8, Issue 6, Page 99-104, December 2025.
Abstract Wire arc additive manufacturing (WAAM) is a robotic metal 3D printing technique that enables the efficient and cost‐effective production of large‐scale structural components with complex geometries. The undulating surface geometry inherent to the WAAM process can be leveraged to enhance the bond strength at the interface between the steel and ...

Out‐of‐plane stability of CFST parabolic arches

ce/papers, Volume 8, Issue 6, Page 227-232, December 2025.
Abstract Owing to their superior composite performance, concrete‐filled steel tubular (CFST) arches have been increasingly employed in bridge construction, with parabolic arches accounting for nearly half of such applications. The excellent mechanical properties of CFST arches often lead to slender designs, making their out‐of‐plane stability a ...
