Project Objective |
To study the effect of long-term conditioning on the behavior of GFRP reinforced panels. | ||||
Project Abstract |
Since 1998, Missouri S&T/University of Missouri-Rolla investigators have been involved in more than 25 bridge repairs and/or new bridge construction involving composite materials. To date, many of these projects have shown reliable field performance. However, there have been little follow-up investigations to study their residual capacity and behavior after long-term exposure to conditioning. This study will examine the crack pattern development over time in GFRP reinforced panels fabricated in 2005 and exposed to field conditions. The study will also test and autopsy the GFRP reinforcing bars to examine property degradation. The GFRP reinforced panels will be studied in flexure to examine any degradation in flexural behavior. |

Relationship to other Research/Projects |
Since 1999, Missouri S&T/University of Missouri-Rolla investigators have been involved in more than 25 bridge repairs and/or new construction involving composite materials. This project will provide valuable information on GFRP bars exposed to ambient conditions of Missouri weathering and stress over eight years. |
