“…In such a failure mode the fatigue failure of the beam is primarily governed by the fatigue life of the steel reinforcement, rather than the concrete or FRP (Barnes and Mays 1999;Masoud et al 2001;El-Hacha et al 2003;Aidoo et al 2004;Heffernan and Erki 2004;Brena et al 2005;Toutanji et al 2006). However, in all previously reported studies, some extent of debonding of the FRP from the concrete substrate has been observed.…”

Many concrete structures are vulnerable to extreme loadings such as accidental impact, terrorist attack and earthquake disasters. Retrofitting of existing concrete structures for enhanced performance under these loadings has been an important topic of research for a long time, especially since the 911 terrorist attack. Among the different retrofitting techniques, external bonding of fibre reinforced polymer (FRP) composites has been a popular one. This paper presents a brief review of recent research on FRP strengthened concrete structures under blast, impact, earthquake and cyclic loading.

“…The mechanism of flexural improvement has been shown to be through increasing fatigue life by reducing the magnitude of steel stress when used to reinforce girders, which are structural beams. [1] Published studies have investigated the effects of CFRP on shear resistance. One such study investigated the use of L-shaped CFRP plates on a shear deficient concrete structure.…”

Carbon fiber (CF) consists of a multitude of unique physical, chemical and biological characteristics that can be utilized and exploited for a number of diverse applications. Found in aerospace systems, structural elements, energy storage and other products, the most recent application of CF has expanded into the realm of surgical implants. The material properties of CF, historical development and applications and methods of manufacturing are illustrated upon. The various surgical applications of CF are defined, from biocompatibility within the human body and wound healing products to numerous surgical implantations. Keywords: carbon fiber; orthopedics; historical review

“…Harries et al (2007) studied the effect of adhesive stiffness; the results showed that the generated stress in tensile steel under fatigue loading was greater with more flexible adhesive due to reduce ability of the adhesive to transfer stress to the strengthening material. From most of the studies Toutanji et al 2006;Barnes and Mays 1999;Shahawy and Beitelman 1999;Papakonstantinou et al 2001;Aidoo et al 2004;Masoud et al 2001;Dong et al 2011), the general behavior of beams strengthened with FRP is that there is an initial change in stiffness and increase of deflection due to a redistribution of the cracks in the beams. This is then followed by unchanging stiffness with increasing deflection due to the cyclic creep, the time evolution of the plastic strain under cyclic load, of the concrete as explained by Papakonstantinou et al (2001).…”

This paper presents a state of the art review of different material combinations and applications of mineral-based and epoxy-based bonded Fiber Reinforced Polymers (FRP), used for the strengthening of concrete structures subjected to fatigue loading. In this review, models of the fatigue life at the material and structural level are presented. This study examines the mechanical behavior of the FRP-material, surface bonding behavior and concrete beams strengthened under fatigue loading with different types of FRP-systems. The parameters that are investigated are applied load value, time dependent effects, type of strengthened structures (shear, flexural or combined) and the configuration of sheets or plates. The building codes and researchers' recommendations are also discussed. As a result of this review, the reader will obtains an overview of suitable materials and methods for strengthening structures subjected to fatigue loading by referring to the estimated fatigue life of material and strengthening structures at various applied stress levels.
