Popis: | Presented here are the results of assessing the effect of elevated temperature on the strength characteristics of reinforced concrete structures during operation. Described here are the features of the technical inspection of structures subjected to temperature effects (after a fire). The strength class of reinforced concrete structures was determined before temperature exposure (in places that were not exposed to fire) and after in the course of the study. Presented are the results of measuring the strength of concrete by the direct method of pulling off with spalling, as well as the results of verification calculations of reinforced concrete structures exposed to temperature effects. When performing verification calculations, the percentage of reduction in the bearing capacity of structures was established. Based on the results of the study, the percentage ratio of the decrease in the strength of prefabricated reinforced concrete structures after a fire during the operation of the facility was established. |
