Experimental Investigation OF Reinforced Concrete Beams with Pre-Organized Cracks under Long-term Loading

The paper presents the results of reinforced concrete beam tests in crack resistance, deformability under long-term loading. The study allowed evaluation stiffness and cracks resistance of reinforced concrete beam using pre-organized cracks and conventional reinforced concrete beam under long-term loading. The results of deflection of rein-forced concrete beams with pre-organized cracks under the action long-term…

Experimental investigation of deflected mode of the reinforced concrete beams with organized cracks under long-term loading

The experiments confirmed the hypothesis about the beams rigidity with pre-organized cracks in comparison with stochastic cracks under the influence of long-term loading. As a result, the beams with pre-organized cracks provide the smaller deflection after long-term period than the beams without organized cracks. Thus, the proposed method of the deflections calculation of the reinforced…
