Reliability Assessments of Concrete Filled FRP Tube Columns Zhou Yingwu1, a, Xing Feng 1,b and Sui Lili 1,c 1Guangdong Provincial Key Laboratory of Durability for Marine Civil Engineering, Faculty of Civil Engineering, Shenzhen University, Shenzhen, the People’s Republic of China aywzhou@szu.edu.cn, bxingf@szu.edu.cn, csuill8969@163.com Keywords: FRP tube columns, reliability index, partial safety factor, confined concrete.
Considering the actual situation in engineering applications, to reach a target reliability index of 3.5, a partial safety factor of 1.4 is finally recommend for both FRP and concrete.
Therefore, the concrete filled FRP tube column has attracted extensive attentions in engineering applications and it is worthy of systematical investigation on the reliability design of the column.
As in engineering applications, the COVs of concrete and FRP strength of 0.1 and 0.15 are commonly obverted respectively and the FRP confinement ratios Rf of 0.3-0.5 (this confinement level is corresponding to 80%-100% strength increment of the column due to the FRP tube confienment) is reasonably accepted, the FRP partial safety factor of 1.4 is finally recommended according to the investigations in this paper (see Fig.2).
Considering the real situations in engineering applications, it is finally recommended that a partial safety factor of 1.4 is proposed both for FRP and concrete.
