Abstract
We experimented with RC members which had limited to shear crack position with notch to estimate shear strength of RC members with fiber sheets. In these experiments, we investigated effective bond area of fiber sheets which contributed to shear strength. It is possible to estimate the improvement of the RC member with the fiber sheets by applying effective bond area to the equation of bond strength between the fiber sheet of the research by which we reported. Moreover, we investigated the effect of shear strengthening of RC beams with fiber sheets and the effect of prestressed force introduced into a part of fiber sheets. As results of these experiments, the effect of shear strengthening by fiber sheets and prestressed force was clarified. Moreover, the experiment value can be estimated by the calculation.
