Analysis and design of eccentrically compressed ultra-high-strength slender CFST circular columns

Abstract

There has been an increasing interest in the application of ultra-high-strength concrete considering the high strength and stiffness compared to conventional concrete. The current international design standards do not allow for the use of ultra-high-strength concrete in composite members. This is due to the limited studies on ultra-high-strength CFST circular columns. In line with this, the objective of the current paper is to obtain an inelastic behaviour of ultra-high-strength slender CFST circular columns when subjected to eccentric compression loads. No previous numerical study has investigated the axial load-moment performance of ultra-high-strength slender CFST circular columns loaded ..
