Influence of Number of FRP layer on Compressive Behavior of FRP-Confined Lightweight Concrete

Abstract

This paper presents the results of an experimental study that was undertaken to investigate the effects of the number of FRP layer on the compressive behavior of fiberreinforced polymer-Confined Lightweight Concrete Columns (FCLCs). A total of 6 lightweight concrete were manufactured and tested under axial compression. The results indicate lightweight concrete in a FCLCs system is confined effectively by FRP. The results also suggest that increasing the number of FRP layer leads to an increase in the ultimate axial stress and strain of concrete FCLCs.
