Carbon
fiber reinforced polymer (CFRP) sheets have established a strong position as an
effective method for innovative
structural rehabilitation. However, the use of
externally bonded CFRP in the repair and rehabilitation of steel structures is
a relatively new technique that has the potential to improve the way structures
are repaired. An important step toward understanding bond behaviour is to have
an estimation of local bond stress versus slip relationship. The current study
aims to establish the bond-slip model for CFRP
sheets bonded to steel plate. To
obtain the shear stress versus slippage relationship, a series of double strap
tension type bond tests were conducted. This paper reports on the findings of
the experimental studies. The strain and stress distributions measured in the
specimens for two different bond lengths. The results show a
preliminary bi-linear bond-slip model may be adopted for CFRP sheet bonded with steel
plate.
