Interfacial bond-slip degradation relationship between CFRP plate and steel plate under freeze-thaw cycles

The bond-slip degradation relationship of a carbon fiber reinforced polymer (CFRP)-steel bonded interface is crucial for predicting the long-term behavior of CFRP-strengthened steel structure under a freeze-thaw (F-T) environment. A total of 16 single-shear bonded joints were tested to investigate the effect of the bond length and the F-T cycles on the CFRP-steel bonded interfaces. The strains on the CFRP surface and the relative slips between...
