Title of the articleAnalysis of normative approaches to strength assessment of normal section bending members with fiber-reinforced polymer reinforcement
Abstract.From the analysis of normative approaches to strength assessment of normal section of fiber-reinforced polymer (FRP) reinforced bending structures in SP 63.13330.2012, ACI 440.1R-06 and fib Bulletin 40 guidelines, a range of relevant study issues was developed. Also features and differences were found in the considered methods of design. A certain criterion for defining the mode of failure of bending concrete members has not been formulated. The values of balanced reinforcement ratio different in various design guidelines. Depending on the grades of concrete, the difference between the values ranges from 13 % to 100 %. As distinct from SP 63.13330.2012 in CAN/CSA-S806-02 and ACI 440.1R-06 guidelines is recommended to design constructions based on the failure of the member is initiated by crushing of the concrete. Considering the safety factor leads to sufficient reduction of reinforcement resistance estimated values and of respective cross sections timing values: for short duration loads – up to 0,4-0,6 and for permanently acting loads – up to 0,14-0,36.
Keywords.Fiber-reinforced polymer, strength of normal sections, concrete structures, bending members.
