Abstract:

Along with our country construction level enhancement,the use of fiber-reinforced polymers(FRPs) for strengthening and rehabilitating reinforced concrete structures has been widespread implementation in recent years.To date,one major factor preventing the widespread use of CFRP materials in buildings is the lack of information available on the fire performance of CFRP-strengthened concrete members during fire in the regulations,and that for the constructed structures,is also lack of the essential scientific basis.Therefore,recent research gap analyses for the fire resistance of strengthened members have identified fireproof design method as an area in which additional information is urgently required.This paper presents a review of research conducted to investigate the fire performance of CFRP material.Also presents an overview of research program to investigate the performance in fire of CFRP-strengthened reinforced concrete slabs,beams and columns.The remained problems for the fire r...更多esistance research of structures and the further research direction are pointed out.

Key words: CFRP-strengthened reinforced concrete, thermal performance, thermodynamic performance, fire resistance test researches
