| Title of the article | Experimental studies of flexural members with fiber-reinforced polymer reinforcement |
| Abstract. | The article presents the results of experimental studies of strength, crack resistance and deformability of normal sections flexural members with fiber-reinforced polymer (FRP) reinforcement. The beam specimens were subjected short duration loads. The experimental data were compared with the theoretical. Calculation methods used by guidelines: USA ¬– ACI 440.1R-06, EU – fib Bulletin 40 and Russia – project SP 63.13330.2012. According to the results of the analysis of the results of some conclusions. Methods SP 63.13330.2012, ACI 440.1R-06 and fib Bulletin 40 understate the ultimate limit state of beams. The experimental values of destructive efforts for beams, reinforced fiberglass reinforcement exceed the theoretical carrying capacity, calculated by SP, in 1,5-3,7 times, reinforced basalt-plastic reinforcement – in 1,522-2,053 times. This is caused by using excessive safety factors, 0,14-0,6 order. Understatement design resistance tensile FRP leads to an inaccurate definition of modes of flexural failure and over-reinforced structures. The maximum deflections of beams reinforced by FRP were (1/29-1/46) lo. The fixed modes of flexural of pulling reinforcement indicates the need within the calculation of flexural members of strength a sufficient value of make check of anchoring. The findings suggest about the possibility, the need to improve methods of calculation: corrections safety factors and calculated equations. |
