Abstract
[ES] This work explores by photogrammetrical techniques the behaviour of inclined sharp cracks in a series of four reinforced concrete beams (HA) and polypropylene fibre-reinforced concrete (HRFP) with and without transverse reinforcement. Particular attention is paid to assessing the movement and slippage of cracks. The results obtained are compared with results measured during the instrument test (SDLs). It is noted that with the use of synthetic fibres dosed at 10 kg/m³, the opening of the main diagonal cracking is significantly reduced in the order of one third. In addition, there is a non-linearity of the opening — slip ratio along the main diagonal cracking. Finally, opening relationships — slips that can be used in Push — off Ortiz Navas, F. are provided; Navarro Gregori, J.; Serna Ros, P. (2018).
