Проведенный анализ охватывает ключевые аспекты деградации строительных конструкций в экстремальных эксплуатационных условиях, включая комплексное воздействие низкотемпературных циклов, динамических нагрузок и коррозионных процессов. Исследованы механизмы ускоренного старения бетонных структур при комбинированном влиянии климатических и эксплуатационных факторов, характерных для регионов Сибири и Дальнего Востока.</p><p>   Особое внимание уделяется вопросам совместной работы бетона, стальной арматуры и внешнего композитного армирования на основе углепластиков с позиций механики деформирования и долговременной адгезионной устойчивости композитно-бетонных систем.</p><p>   Приведены результаты отечественных и зарубежных исследований, указывающие на существенные преимущества данного способа усиления, такие как минимальное увеличение массы конструкций, технологичность монтажа в стесненных условиях и устойчивость к агрессивным средам, а также определенные ограничения и особенности монтажа. Проанализированы современные методики обеспечения качества адгезионных соединений, включая подготовку поверхностей, температурные режимы полимеризации и методы неразрушающего контроля. Систематизированы критерии выбора технологических решений в зависимости от типа повреждений, эксплуатационных нагрузок и климатических факторов. Согласно исследованию, использование углепластика в качестве внешнего армирования демонстрирует высокую эффективность и экономическую целесообразность. Данная технология отвечает современным запросам по восстановлению инфраструктуры, позволяя проводить работы с минимальными помехами для эксплуатации и гарантируя прогнозируемый срок службы усиленных конструкций.</p></abstract><trans-abstract xml:lang="en"><p>   This article discusses the prerequisites for strengthening reinforced concrete elements, as well as the effectiveness of using composite materials in harsh climates and seismic activity. The analysis covers key aspects of the degradation of building structures under extreme operating conditions, including the complex effects of low-temperature cycles, dynamic loads, and corrosion processes. The mechanisms of accelerated aging of concrete structures under the combined influence of climatic and operational factors characteristic of the regions of Siberia and the Far East are investigated.</p><p>   Special attention is paid to the issues of joint work of concrete, steel reinforcement and external composite reinforcement based on carbon plastics from the standpoint of deformation mechanics and long-term adhesive stability of composite concrete systems.</p><p>   The results of domestic and foreign studies are presented, indicating the significant advantages of this reinforcement method, such as a minimal increase in the mass of structures, technological installation in cramped conditions and resistance to aggressive environments, as well as certain limitations and installation features. Modern methods for ensuring the quality of adhesive joints, including surface preparation, temperature polymerization solutions, and non-destructive testing methods, are analyzed. The criteria for the selection of technological solutions are systematized depending on the type of damage, operational loads and climatic factors. According to the study, the use of carbon fiber as an external reinforcement demonstrates high efficiency and economic feasibility. This technology meets modern demands for infrastructure rehabilitation, allowing work to be carried out with minimal interference to operation and guaranteeing a predictable service life of reinforced structures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жизненный цикл объекта строительства</kwd><kwd>эксплуатационная надежность</kwd><kwd>техническое состояние</kwd><kwd>продление срока службы</kwd><kwd>капитальный ремонт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>life cycle of the construction site</kwd><kwd>operational reliability</kwd><kwd>technical condition</kwd><kwd>prolongation of service life</kwd><kwd>major repairs</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Онуфриев Н.М.
