THE SAFETY DEGREE OF RC STRUCTURE STRENGTHENEDWITH FIBER REINFORCED POLYMER

Abstract

Abstract: In order to further understand the safety degree of RC structure strengthened with fiber reinforced polymer (FRP), the safety degree of the Chinese code (GB50608) and the American guildline (ACI440) are discussed. Based on reviewing on the load and reisitence factor expression and the resistance factors in different reports. It shows that the safety degree of Chinese code is lower than American guildline, the resistance factors can not well express the relationship between the performance of strengthening structure and the safety margin. Thus, some suggestions for furture research are put forward to solve the problems existing in current Chinese code.

Key words: fiber reinforced polymer, concrete structure, reinforcement, safety degree
