COMPRESSIVE PERFORMANCES OF THE CONCRETE

2012-8-4  This paper presents the results of axial compressive tests of the concrete filled circular CFRP-steel tubular (C-CFRP-CFST) stub columns. The test results showed that the CFRP jackets enhanced the load bearing capacity of the stub columns effectively. Enhancement of the columns' stiffness due to the CFRP jackets was also observed.

Compressive behaviours of circular concrete-filled

2020-6-10  The explanations to these observations are (1) firstly, exposed to low temperature, both compressive strength of steel and concrete are improved that results in the increased compressive strength of CCFST-SC; (2) secondly, at low temperatures the steel materials contract faster than the concrete core that results in higher confining stress on the concrete core and improves its

Compressive performances of concrete filled Square

2014-5-25  Sixteen concrete filled square CFRP-steel tubular (S-CFRP-CFST) stub columns under axial compression were experimentally investigated. The experimental results showed that the failure mode of the specimens is strength loss of the materials, and the confined concrete has good plasticity due to confinement of the CFRP-steel composite tube.
