Axial compression performance analysis and bearing capacity calculation on square concrete-filled double-tube short columns

Marine Structures, 2020
The concrete-filled double-tube (CFDT) columns have been proposed in recent years. The existence of inner steel tube can not only increase the confinement on core concrete, but also increase its fire resistance and anticorrosion performance.

Constitutive behaviour of high-performance ferrocement under axial compression

Magazine of Concrete Research, 2006
The increased utility of ferrocement for stressed skin surfaces such as domes, arches, funicular shells etc, necessitated further research and development for better performance. The aim of the current paper is to develop an analytical model for predicting the stress–strain behaviour of an improved ferrocement, based on the experimental results.

Axial-Compression performance and finite element analysis of a Tubular Three-Dimensional-Woven Composite from a Meso-structural approach

Thin-walled structures, 2020
The concept of green environmental protection is becoming increasingly important. This study used green high-performance basalt-fiber filament tows as raw materials to prepare tubular three-dimensional (3D)-woven preforms on a semi-automatic loom.

Performance of hexagonal CFST members under axial compression and bending

Journal of Constructional Steel Research, 2016
Abstract The compressive and flexural behavior of the hexagonal concrete-filled steel tubular (CFST) members is investigated in this study. Tests are carried out on the specimens under axial compression and bending. The parameter of the experimental work is the steel ratio of the cross section, and the hollow tubular members are designed for ...

Axial Compression Performance of Sprayed Steel Fiber Recycled Concrete

Current Materials Science
Sprayed steel fiber reinforced recycled concrete (SSFRC), as a green product of small particle size recycled aggregate (RA), was tested for compressive performance using an electro-hydraulic servo pressure testing machine. The replacement rate of RA, the volume ratio of Steel Fiber (SF), and the strain-stress curve of SSFRC were studied.

Predictable and consistent performance of angular packing in axial compression columns

Journal of Chromatography A, 1994
Abstract Various silica-based angular materials were packed and tested in a dynamic axial compression (DAC) column. Effects of packing pressures and solvents on the performance of the angular packings in DAC columns were examined. Column performance ( i.e.

Experimental study on the axial compression performance of GFRP-reinforced concrete square columns

Advances in Structural Engineering, 2018
At present, extensive studies have been conducted relative to the topic of fiber-reinforced polymer(FRP)- reinforced concrete (RC) flexural members, and many design methods have also been introduced. There have, however, been few studies conducted on the
