Performance of Hollow Concrete Filled Circular Steel Tube Column Subjected Axial Loading
Journal of Physics: Conference Series, 2023 Abstract To improve the behavior of hollow concrete filled steel tube, a novel type of reinforced hollow concrete circular steel tubular member (RHCFST) was put forward and its axial behavior was studied. The finite element analysis model of 12 RHCFST short columns under axial compression was established by using ABAQUS. The influence of

Tensile behaviour of headed anchored hollo-bolts in concrete filled hollow steel tube connections
Engineering Structures, 2021 Abstract Achieving a strong and stiff bolted connection with concrete filled steel tube (CFST) has been a challenge to structural engineers, and therefore to enhance the connection performance, blind-bolts that are extended to anchor in the concrete core have been recently developed.

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 ...
