| Title of the article | Evaluation of the residual load-bearing capacity of operated reinforced concrete structures. |
| Abstract. | During the operation of buildings and structures made of reinforced concrete, defects and damages heat up in the structures over time. In order to correctly resolve the issue of the possibility of further safe operation or reconstruction of buildings and structures, it is necessary to be able to assess the technical condition of reinforced concrete structures based on the results of their examination, taking into account existing defects and damages. The aim of the study is to develop, based on theoretical studies, the equations of the objective strength of the concrete of the compressed zone and the longitudinal stretched reinforcement of the bent reinforced concrete element with defects and damages. The objectives of the work are: to establish a scheme for the formation of cracks in the operated bent reinforced concrete element; to develop an equation of the objective strength of the concrete of the compressed zone and the stretched reinforcement of the reinforced concrete bent element, taking into account the influence of existing defects; to develop a methodology for calculating the residual load-bearing capacity of the operated bent reinforced concrete element, taking into account the influence of existing defects. Results. A methodology has been developed for assessing the residual load-bearing capacity (resource) of operated reinforced concrete structures, taking into account the influence of various defects and damages accumulated during operation. Conclusions. The significance of the results obtained for the construction industry lies in the fact that they allow for a more accurate and reliable assessment of the residual load-bearing capacity of the operated reinforced concrete structures, taking into account the accumulated defects and damages during operation. |
