Research on the Residual Bearing Capacity of Square Hollow Concrete-filled Steel Tube After Fire

Highlights in Science, Engineering and Technology, 2023
In order to study the change of the residual bearing capacity of square hollow concrete-filled steel tube after fire, the finite element analysis software ABAQUS was used to establish the finite element model of square hollow concrete-filled steel tube under the ISO-834 standard fire heating condition, and the temperature distribution and deformation ...

Structural response of concrete-filled elliptical steel hollow sections under eccentric compression [PDF]

, 2012
The purpose of this research is to examine the behaviour of elliptical concrete-filled steel tubular stub columns under a combination of axial force and bending moment. Most of the research carried out to date involving concrete-filled steel sections has

Experimental Study on Supporting Capacity of Hollow Reinforced Concrete Filled Steel Tube

Journal of Physics: Conference Series, 2023
Abstract Hollow reinforced concrete supported specimens with different slenderness ratio and steel content were designed and the load-displacement test was carried out. The load-displacement curve of hollow reinforced concrete filled steel tube supported showed no obvious decreasing section, and the curve remained almost unchanged or ...

Performance of Prefabricated Hollow Concrete-Filled Steel Tube Bracings on Transverse Bending: Experimental and Numerical Analyses

Journal of Marine Science and Engineering, 2023
Due to the complex hydrogeological conditions in coastal regions, the use of internal bracing systems is necessary for supporting coastal foundation pits. This paper introduces a novel prefabricated foundation pit bracing system based on Hollow Concrete-Filled Steel Tube (H-CFST) structures that can be reused, offering significant economic and societal
