A regulatory framework is required to ensure the correct design of Fibre-Reinforced Polymers (FRPs) increasingly being used as an externally-bonded strengthening system on concrete columns. Several guidelines confinement FRP have been developed over past few years worldwide, each proposing a different approach, resulting in predictions. This study aims evaluate and compare nine international pr...

Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The te...

The application of concrete is severely limited in construction cold areas. However, the local ice has functioned as a potential substitute for long time. In order to make efficient use overcome its weaknesses low strength and poor ductility, an innovative type ice-filled large rupture strain (LRS) fiber-reinforced polymer (FRP) tube column was developed. system consists external LRS FRP tubes ...

Abstract Many existing structures show insufficient seismic capacity, with the lack of members' ductility being a critical factor. Aim is to manage increase their ductility, through confinement composite fiber reinforced polymer (FRP) sheets. In present paper, available analytical procedures Eurocode 8‐Part 3 (2005) and draft 2022 Greek Code for Structural Interventions (CSI) 2013 revision are ...

The axial compressive strength of unidirectional FRP made by pultrusion is generally quite lower than its axial tensile strength. This fact decreases the advantages of FRP as main load bearing member in engineering structure. A theoretical iterative calculation approach was suggested to predict the ultimate axial compressive stress of the combined structure and analyze the influences of geometr...

reliable stress-strain behavior of concrete is necessary particularly when a member is subjected to combine bending and axial load and confinement effects should be accounted for. a unified theory for confinement of circular hollow sections is proposed herein, that can be extended to the case of solid and noncircular sections. the main aim of the model is to trace step-by-step the evolution of ...

Emulsion polymerization process provides a unique polymerization locus that has a confined tiny space with a higher polymer concentration, compared with the corresponding bulk polymerization, especially for the ab initio emulsion polymerization. Assuming the ideal polymerization kinetics and a constant polymer/monomer ratio, the effect of such a unique reaction environment is explored for both ...
