Existing research works have established that Drucker–Prager (DP) plasticity model is
capable of modeling stress–strain behavior of confined concrete. However, accuracy of the …

A general mathematical model is developed to describe the stress–strain (fc–εc) relationship
of FRP confined concrete. The relationship is applicable to both circular and rectangular …

This paper first presents a critical review and assessment of the ability of the existing
Drucker–Prager (D–P) type concrete plasticity models to predict the behavior of confined …

Commonly used fiber-reinforced polymer (FRP) includes Carbon, Glass, and Aramid FRP
composites. Meanwhile, some new FRPs such as PBO (Polypara-phenylene-Benzo-bis …

The constitutive relationship of concrete under passive confinement of fibre reinforced
polymer (FRP) is one of the fundamental requirements for mechanical analysis of FRP …

The stress-strain relationship of FRP confined concrete columns under eccentric loading is
different from that under concentric loading. However, eccentric loading can have different …

This study is dedicated to the development of a generalized confinement model applicable
to circular concrete columns confined by FRP full and partial confinement arrangements. To …

Concrete dilation is one of the main parameters that controls the stress–strain behaviour of
confined concrete. Several analytical studies have been carried out to predict the stress …

This paper presents a plasticity constitutive formulation for actively and passively confined
concrete. The loading surface is based on Menetrey and Willam's model with an additional …

This study provides new insight on the compressive behaviour of partially fibre reinforced
polymer (FRP) confined concrete with either strain-hardening or strain-softening responses …
