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 …

Modeling confined concrete using plasticity models for actively confined concrete is well
established. However, for passively confined concrete with very high lateral stiffness, it is …

The confining stress in FRP (fiber reinforced polymer) confined concrete is dependent on the
lateral strain of the concrete but the lateral strain of the concrete is dependent on the …

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 …

The use of fiber-reinforced polymers (FRP) has become widely accepted engineering
practice for strengthening reinforced concrete members. It is well established that lateral …

A method is presented for the assessment and calibration of the elastoplastic behaviour of
FRP confined concrete. The method is based on the evaluation of permanent deformations …

The passive confinement of externally wrapped fiber-reinforced polymer (FRP) composites
can effectively restrain the unstable lateral expansion of confined concrete, hence results in …

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

This paper presents the results of an experimental study on the behavior of concrete
confined by fiber reinforced polymer (FRP) jackets with a large rupture strain (LRS). The …

Poor quality of concrete and lack of sufficient transverse reinforcement are among the most
common deficiencies for many existing reinforced concrete structures. These deficiencies …
