摘要
Abstract
More and more attention has been paid to the debonding failure of reinforced concrete beams strengthened with fiber reinforced polymer(FRP) by many researchers home and abroad in recent years and a great number of experiments have also been made. Though a lot formulations for calculating the failure load of end debonding have been verifed, as for the intermediate cracking debonding, most of the researches are about the distribution of shear stress along the binding surface and the strain of FRP. According to the strength-based models few formulations have been put forward to calculate the carrying capacity of intermediate crack debonding. On the basis of a lot of references a simplified formulation based on the energy-based models has been put forward in this paper for calculating the flexural capability of strengthened beams with intermediate cracking debonding.关键词
