The article deals with the main results of experimental studies of strength, crack resistance and informational content of the diagonal and normal sections of common damaged and brought to the critical state of the first group r. c. - beams reinforced with carbon fibre sheet in the lower tensioned zone and on the support area. According to the adopted methodology, an experiment was conducted on the four-factor three-level BoxBenkin B4 plan. The average relative deformation values of the compressed concrete in the middle part of beams after their stabilization under low-cycle static loading have been evaluated. Tests of prototypes were carried out according to the scheme of single-track free-beam, alternately loaded from above, then from below by two concentrated forces without changing its position. |
