Numerical Analysis of the Axial-Flexural Behavior of CFST Columns with Active Transverse Prestressing

This paper presents a numerical study on the vertical (axial) and lateral (flexure) behavior of CFST (Concrete-Filled Steel Tube) columns with active hoop prestress achieved by bolting together two steel half-tubes. Twelve prototype CFST column specimens differing in the prestressing force (three le...
