Creep investigation of GFRP RC Beams - Part A : Literature review and experimental Study

Abstract

GFRP composite bars are excellent alternative to steel bars for reinforcing concrete structures in severe environments. However, studies on creep phenomenon of GFRP reinforced concrete structures are limited. Creep occurs as a result of long term exposure to high levels of stress that are below the yield strength of the material. This paper (Part A) presents a literature review and the loading history of six experimental beams reinforced with GFRP and steel bars. The results of this study revealed that Beams reinforced with GFRP are less marked with creep phenomenon. This investigation should guide the civil engineer/designer for a better understanding creep phenomenon in GFRP reinforced concrete members.
