| Title of the article | Calculation of the bending deflections of reinforced concrete elements with regard to joint action of bending moments and shear forces using a non-linear deformation model |
| Abstract. | The aim of this work was the determination of the bending deflections of reinforced concrete elements with regard to combined action of bending moments and shear forces using nonlinear deformation model. Using mathematical analysis program – MathCAD – the algorithm of calculation of concrete and reinforced concrete beams was elaborated. It takes into account the scheme of loading, nonlinear properties of concrete and reinforcement, the emergence and development of normal cracks. The algorithm allows the use of state diagrams concrete, obtained by the authors previously. The article describes the calculation of the single beams, the results of which specify the position of the norms about the possibility of calculation of the bending deflections of reinforced concrete elements on the action only moments without taking into account shear forces. However, the data obtained by the program selected areas of research have shown that depending on circuit loading, the relationship l/h and a/h, the percentage of longitudinal reinforcement, types of deformation diagram of materials, development of inclined cracks, presence of prestressing reinforcement, and stresses the influence of shear forces on the deflection can reach 80 %. Therefore, there is a need to develop techniques for determination of deflections taking into account these factors, which will be discussed in further publications. |
