State–of–the–art review of FRP composites for major construction with high performance and longevity

0
This paper first identifies the need for high performance and longevity of major engineering structures focusing on the problems in current civil infrastructure. Subsequently, it reviews the state–of–the–art research of FRP in structural retrofitting and strengthening and identifies the challenges facing further development of FRP in civil engineering. In order to address the above background, several key scientific issues and corresponding research directions are introduced according to the newly granted National Key Basic Research Program in China, which comprises of: 1) fracture/failure control and probabilistic design of FRP composites and large FRP–reinforced concrete structures; 2) long life–cycle fatigue and creep characteristics as well as service life controllability design of FRP–reinforced structures subjected to multi–field coupled actions; 3) performance of FRP–reinforced structures subjected to extreme environments and extreme loadings as well as methods for performance control; 4) key technologies and their integration for the application of FRP composites in major engineering structures.

Keywords: fibre reinforced polymers, FRP composites, structural retrofitting, structural strengthening, major structures, high performance, longevity, civil infrastructure, fracture control, failure control, probabilistic design, reinforced concrete structures, fatigue, creep, service life design
