| Title of the article | Numerical studies of self-stressing of composite beams |
| Abstract. | Problem statement. The main purpose of the investigation is to use the internal stressed-deformed state of the steel-concrete composite beam for self-stressing. Solved the problem of prestressing a composite steel beam with the account of shrinkage of concrete and the introduction of a temporary support on the effect of operational loads (temporary support removed). Expressions of internal forces (moments and other internal forces) for the composite section are recorded, and numerical experiments on the analysis of the self-stressing process of the beam are carried out. Results. The main results of the investigations consist the identification of a number of principal positions of the stress-strain state of the self-stressed steel-concrete composite beam and the evaluation of numerical results of beam research without prestressing and self-stressing. Conclusions. The significance of the results obtained for the construction industry is to identify the stressed state of the beam of the composite section from the shrinkage of concrete with of internal stresses for self-stressing the beam. The obtained dependences can be used in the construction of beam structures of the composite section in new construction and in the restoration of the floors of architectural heritage buildings. |
