Bond-slip model between anchored CFRP strip and concrete by using ANN

摘要

For the last 20 years, carbon fiber reinforced polymers (CFRP) have beenwidely used in the retrofitting and strengthening of structures with inadequateearthquake performance. One of the most important design criteria in retrofittingand strengthening details developed with CFRP is delaying the debondingof CFRP strips from the surface. For this reason, the use of anchors in reinforcementdetails developed with CFRP has increased. In this study, availableexperimental data in the literature on bond-slip research related to anchoredCFRP strips were collected and a database was created. By using this database,it was aimed to create a generalized capacity equation and constitutive bondslipmodel for anchored strips via the artificial neural networks technique. Theproposed NN models on the constitutive bond-slip model are intended to beuseful in design codes and finite element algorithms.
