Different from the typical bi-linear stress-strain response, many recent studies have reported
a stress reduction-recovery response (ie, a three-segment behavior of strain hardening …

One important application of fiber reinforced polymer (FRP) composites in the retrofit of
reinforced concrete structures is to provide confinement to columns for enhanced strength …

Extensive experimental and theoretical studies have been conducted on the compressive
strength of concrete-filled steel tubular (CFST) columns, but little attention has been paid to …

A novel column consisting of steel, concrete and fiber-reinforced polymer (FRP) is presented
and assessed through experimental study. The sectional form of steel–concrete–FRP …

This paper presents a modified plastic-damage model within the theoretical framework of the
Concrete Damaged Plasticity Model (CDPM) in ABAQUS for the modeling of confined …

Fiber-reinforced polymer (FRP) jacketing has become an attractive technique for
strengthening/retrofitting reinforced concrete (RC) columns. Extensive research has been …

Jacketing confines concrete, and hence increases the strength and ductility of jacketed
columns. A significant amount of research has been devoted to circular columns that have …

This paper presents a unified stress–strain model of concrete for circular, square, and
rectangular columns confined by fiber-reinforced polymer (FRP) jackets. Through the …

In this study, 68 reinforced concrete columns were tested under uniaxial compression after
being jacketed externally with carbon fiber-reinforced polymer (CFRP) sheets. Forty …

This paper presents the results of an experimental study on the behavior of axially loaded
short rectangular columns that have been strengthened with carbon fiber-reinforced polymer …
