Student Involvement

One graduate student would be involved in the completion of the project

Project Objective

Study the bond properties of Fiber Reinforced Polymer (FRP) bars by conducting pullout-test using a vertical bond-test specimen using FRP Rods (both Carbon and Glass Based) in accordance with ACI 440k provisions

Project Abstract

The aim of the experimental research is to quantify the bonding properties of FRP rods made of carbon (CFRP) and glass (GFRP) with concrete by conducting two sets of experiments. The first set of experiments would involve pullout tests using vertical bond specimens. The tests would be in accordance with the ACI-440k provisions. Provisions of some recommended bond parameters in ACI 440 R.1 (released in 2001), such as K2 and K3 would be evaluated by performing an analytical study on the experimental data.

Anticipated Benefits

The following benefits are anticipated from the experimental work.
1) Enhance the understanding of the bonding properties which is critical to the application of FRP bars
2) Assist in standardization of code provision in the usage of FRP bars products

Modal Orientation

Experimental evaluation of bond between FRP and concrete
