Abstract:

Strengthening of structures using externally bonded fiber reinforced polymer (FRP) systems is nowadays very popular. There are two major types of applications for externally bonded FRP systems: bond-critical applications (e.g. FRP flexural/shear strengthening) and contact-critical applications (e.g. FRP confinement of columns). In the bond-critical applications, the bond between the FRP and the substrate materials (i.e., concrete or steel) plays a critical role in transferring the force from the structural member to the FRP strengthening layer and influences greatly the FRP strengthening efficiency in terms of both the short-term performance and long-term durability. As the most fundamental issue for the FRP strengthening technology, the bond mechanics of FRP-to-substrate interfaces has received exhausted attention. This lecture presents a state-of-the-art of this topic from fundamental principles to mechanics involved in predicting the interface debonding failure under various applications.
