Железобетонные конструкции могут подвергаться агрессивному воздействию окружающей среды, что приводит к снижению их несущей способности в течение срока службы. Если оценка безопасности таких конструкций должна быть выполнена для возможности продолжения эксплуатации, основной задачей было бы обеспечение их способности выдерживать будущие экстремальные нагрузки в течение предполагаемого срока службы с уровнем надежности, достаточный для безопасности.

В настоящее время не существует методологий для проведения такой оценки.

Настоящая методология предлагается для облегчения количественных оценок текущей и будущей конструктивной надежности и несущей способности железобетонных конструкций. Эта методология учитывает случайный характер прошлых и будущих нагрузок, а также деградацию в результате негативных факторов окружающей среды.

Оценка надежности и износа железобетонных конструкций, зависящая от времени, обеспечивает основу для определения продолжительности безопасной эксплуатации.

Reinforced concrete structures can be exposed to aggressive environmental influences, which leads to a decrease in their bearing capacity during their service life. If a safety assessment of such structures is to be carried out in order to be able to continue in service, the main challenge would be to ensure that they can withstand future extreme loads over their intended lifetime with a level of reliability sufficient for safety.

There are currently no methodologies for such an assessment.

This methodology is proposed to facilitate quantitative assessments of the current and future structural reliability and load-bearing capacity of reinforced concrete structures. This methodology takes into account the random nature of past and future pressures, as well as degradation as a result of negative environmental factors.

The time-dependent reliability and deterioration assessment of reinforced concrete structures provides the basis for determining the duration of safe operation.
