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

Numerical study of the stress-strain state of reinforced concrete beam with pre-organized cracks under short-term and long-term loading
—
by
The article investigates the numerical modelling of deformation process and fracture of the reinforced concrete beams with preformed organized cracks and without preformed organized cracks under the action of short-term and long-term loading. Identified that, the features was changed of stress-strain state of beam during the deformation process and the main factors determining process of…
