DEBONDING FAILURE IN CFRP STRENGTHENED CONCRETE STRUCTURES

In 1999-2000 Australia spent $19 billion on civil engineering infrastructure renewal (3% of the country's GDP). The repair of damaged structures and strengthening of existing structures has become a research priority to maximise the life of aging infrastructure. A method that shows particular promise is the use of CFRP technology to retrofit structures. The repair technology, however, requires development and questions remain as to bonding mechanics and debonding strength of the repair material from the structure. This research will provide high quality experimental data and will develop a rational analytical model for debonding between CFRP plates from the parent concrete.
