Torsional Resistance of High Strength Concrete Filled Steel Tube Beams Stiffened Internally with Steel Bars

Tikrit Journal of Engineering Sciences
The torsional behavior of twelve concrete-filled steel tube (CFST) specimens was experimentally investigated. CFST specimens were reinforced by internal cross-rods with different spacing (0, 50, 100, 150, 200, and 250) mm, different thicknesses of the ...

Parametric Study on the Axial Behaviour of Concrete Filled Steel Tube (CFST) Columns [PDF]

American Journal of Applied Scientific Research, 2017
Concrete filled steel tube (CFST) columns are widely used in civil engineering structures due to its abundant structural benefits like excellent seismic behaviour, ultimate load bearing capacity, fire resistivity, excellent ductility and energy absorption capacity, particularly in zones of high seismic risk.

Behavior of manufactured sand and recycled coarse aggregate concrete‐filled steel tubular stub columns with circular section

Structural Concrete, EarlyView.
Abstract Accelerated urbanization has intensified environmental concerns due to excessive natural resource consumption and construction waste generation. Circular concrete‐filled steel tube (CFST) columns incorporating manufactured sand recycled coarse aggregate (MS‐RCA) concrete have emerged as an innovative composite element offering notable ...

Structural behavior of small square steel tubes reinforced self‐compacting concrete columns under biaxial eccentric loads

Structural Concrete, EarlyView.
Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.

Detecting the interfacial bonding of concrete-filled steel tube columns after fire by two stress wave-based methods – A case study

Case Studies in Construction Materials, 2022
For concrete-filled steel tubes (CFST), the steel tube can increase the stiffness of the member, while the filled concrete prevents column buckling and allows the steel tube to withstand high temperatures for longer periods of time.

External Vibrations on Early‐Age Concrete: A Review

Engineering Reports, Volume 8, Issue 5, May 2026.
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Study on the Bond Strength of Steel-Concrete Composite Rectangular Fluted Sections

Advances in Civil Engineering, 2020
Concrete-filled steel tube (CFST) sections are structural members that effectively use the best properties of steel and concrete. Steel tube at the outer perimeter effectively resists tension and bending moments and also increases the stiffness of the ...

Distributed AutoML framework for multi‐objective optimization of concrete crack segmentation models

Structural Concrete, Volume 27, Issue 1, Page 998-1019, February 2026.
Abstract Monitoring cracks in concrete surfaces is essential for structural safety. While machine vision techniques have received significant interest in this domain, selecting optimal models and tuning hyperparameters remain challenging. This paper proposes a Distributed Automated Machine Learning (AutoML) framework for efficiently designing and ...
