Abstract
The present study investigates the stresses on the concrete substrate at the vicinity of the FRP fabrics. In this experimental research, 4 RC beams are prepared from which 2 beams are unstrengthened and 2 beams are strengthened with CFRP fabrics. Dimensions of the beams are 150mm×150mm×1000mm, and all of them are precracked at the middle section of the beam. The aim of the research is to identify the effect of the cracks on the stresses at the bond region between the FRP layer and the concrete substrate. An innovative experimental process is proposed in order to observe these stresses, which are critical parameters in debonding mode of failure in FRP retrofitted RC beams. © Tsinghua University Press, Beijing and Springer-Verlag Berlin Heidelberg 2011.
