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…

Deformation of reinforced concrete beams with forming elements under long-term loading
—
by
This paper deals to problems of studying cracks in reinforced concrete beams under long-term loading by fundamental of reinforced concrete resistance theory (energy approach) was describe. The experimental study of bearing capacity of reinforced concrete beams with the form of plastic plates (artificial cracks) and without form of plastic plates (artificial cracks) with different coefficients…

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…
