| Title of the article | Analysis of calculation methods flexural members, reinforced fiber-reinforced polymer bars, the serviceability limit states |
| Abstract. | The article presents the results of theoretical and experimental studies of deformability of flexural members with fiber-reinforced polymer (FRP) reinforcement. The study used fiberglass and basalt FRP rebar. The tests were performed at short duration of load application. The study considered calculation methods of guidelines: US – ACI 440.1R-06 and Russia – SP 63.13330.2012. Theoretical data deflections and width of cracks were compared with experimental data. In considered methods parameters varied: in SP 63.13330.2012 factor ?f, taking into account the uneven distribution of the relative strain of tensile reinforcement between the cracks; in ACI 440.1 R-06 factor ?, taking into account the duration of load action. Most similar results to the experimental data has the method of ACI 440.1R-06 at factor ? equal to 2. Based on the results of the analysis of the obtained results developed a series of recommendations: calculation of the strains recommended by the method of SP at factor ?f accepted equal to ?_f=1-0,8?M_crc/M And the ACI method at factor ? equal to 2. The data obtained indicate the need for improvement the calculation of serviceability limit states of SP 63.13330.2012 method. |
