| Abstract: | It is a new technique to embed near-surface mounted(NSM) CFRP rods in a stone beam to improve the flexural performance of the beam,and it can be used for retrofitting existing stone structures.26 pull-out specimens were tested to investigate the bond behavior between CFRP rods and the stone.The main experimental parameters were the diameter of CFRP rod,the bonded length and the thickness of epoxy cover.Test results indicate that there are three typical failure modes,namely tensile rupture of CFRP rod,CFRP r... |
