Abstract

This study aims to investigate the influence of the number of GFRP layers on the axial compressive behavior of FRP-confined lightweight concrete cylinders. Eight lightweight concrete specimens wrapped with 0, 1, 2, and 3 sheets of GFRP were manufactured and tested until failure. The test confirms that the thicker specimens experienced higher axial stress and strain compared to the thinner ones.
