Concrete-filled bimetallic tubes under axial compression [PDF]

, 2016
YesThis paper presents the experimental results of axial compression tests on concrete-filled bimetallic tubes (CFBT). The cross section of the bimetallic tube is composed of an outer layer made of stainless steel and an inner layer made of carbon steel.

Numerical study of the plasticity effect on the behavior of short steel columns filled with concrete loaded axially

Fracture and Structural Integrity, 2022
For more than two decades, the construction technique using concrete filled steel tube (CFST) has been widespread throughout the world. Indeed, it has been demonstrated that the use of normal or high strength concrete, confined in a steel tube of ...

Strength and Deformation of Concrete-Encased Grouting-Filled Steel Tubes Columns Exposed to Monotonic Quasi-Static Loading Conditions

Infrastructures
This study aimed to evaluate the effectiveness of a novel concrete-encased column (CE) using small circular steel tubes filled with cementitious grouting material (GFST) as the primary reinforcement instead of traditional steel bars.

RC column strengthening by lateral pre-tensioning of FRP [PDF]

, 2003
This paper presents a unique strengthening technique for existing concrete columns that use expansive materials to apply lateral pre-tensioning. The technique increases the capacity and ductility of a column as well as achieving better utilisation of the

Effect of Diaphragm Above Concrete-Filled Part on Horizontal Load Capacity of Partially Concrete-Filled Circular Piers Subjected to Axial Forces

Buildings
Partially concrete-filled steel tubes (PCFSTs) are often used to reduce the dead weight of concrete-filled steel tubes (CFSTs). Most previous studies have focused on the presence or absence of diaphragms directly above the concrete filling of PCFSTs, and
