Abstract

Fiber reinforced polymer (FRP) composites have been widely used as externally bonded reinforcements to strengthen or rehabilitate different kinds of deteriorated concrete structures. However, premature debonding failure due to the limitation of bond at the FRP-concrete interface are often encountered under utilizing FRP material potential for strength increase. To minimize debonding failures due to environmental factors such as water intrusion, etc. and other mechanical damage such as vehicular traffic and impact, etc., near surface mounted (NSM) FRP technology has emerged as another structural strengthening method. This study aims at developing a new strengthening system for the rehabilitation of deteriorated concrete structures using prestressed NSM carbon fiber reinforced polymer (CFRP) tendons.
