An experimental study on the structural behavior of water and wastewater supply GFRP pipe

Abstract

In this paper, the results of experimental and analytical investigations pertaining to the structural behavior of glass fiber reinforced polymer plastic (GFRP) pipes are presented. GFRP is assumed as an orthotropic material. Mechanical properties along the longitudinal and hoop direction of the pipes are determined by the tension and compression tests. The parallel plate loading tests for the GFRP pipes were conducted to findthe relation between load and ring deflection. Inaddition, the finite element analysis (FEA) for the GFRP pipes was conducted using the material properties obtained from test in the study. The numerical results obtained by the finite element method show good agreement with the parallel plate loading test results for GFRP pipes. © 2017 Trans Tech Publications, Switzerland.
