Abstract:
The fiber reinforced polymers (FRP) are widely used for strengthening and rehabilitation of concrete and steel structures. One of the serious collapse mechanisms of the Carbon Fiber Reinforced Polymer (CFRP) strengthened steel beam is due to debonding of the CFRP laminates in the vicinity of high stress concentration regions, such as, at the ends of the laminates. There are several analytical solutions for stress analysis of this effect. Nevertheless, most of these methods are applicable only in the elastic range. In this thesis a simple and efficient analysis modeling will be proposed and investigated for reasonable predicting of the debonding effect. The simplified analytical result will be compared to existing experimental results, as will as, with those of finite element analysis results
