This paper addressed about calculation of the deflection of reinforced concrete beams under concentrated load in mid span using different standards such as Russian code and ACI standard, compared with actual beam test result and the result of calculation in computer program ANSYS. As a result, it showed that, when compared with actual beam test…
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…
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…
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…
