Experimental and numerical analysis on the effectiveness of GFRP wrapping system on timber pile rehabilitation

Abstract

Rehabilitation using Glass Fibre Reinforced Polymer (GFRP) wrapping system is an innovative technique for rehabilitation of deteriorated timber structures exposed to severe environmental conditions. This paper investigates the effectiveness of rehabilitation using GFRP wrapping system for deteriorated timber piles due to splitting. An experimental investigation was conducted on undamaged and damaged short timber columns with three levels of splitting. Crane rail epoxy and underwater cementitious grout were used to fill the annulus between columns and GFRP jackets in the rehabilitated samples. All the samples were tested under axial compression loading. Axial peak and yield loads, ductility a..
