    <p>Цель: выполнить расширенный сравнительный анализ современной нормативной базы проектирования железобетонных мостов с учетом воздействия окружающей среды, включая стандарты EN 206 и Eurocode 2, AASHTO LRFD, национальные нормы России и Узбекистана, а также нормативные документы стран Азиатско-Тихоокеанского региона (Япония, Китай, Индия, Австралия, Новая Зеландия). Определить особенности методологических подходов к обеспечению долговечности мостовых сооружений и выявить направления совершенствования нормативных требований в условиях перехода к проектированию по сроку службы и управлению жизненным циклом конструкций. Методы: проведен сравнительный анализ международных и национальных нормативных документов по критериям учета воздействия окружающей среды, назначения, проектного срока службы, применения моделей деградации, вероятностной оценки надежности и интеграции методов Life- Cycle Cost (LCC) и Life-Cycle Assessment (LCA). Выполнен системный анализ нормативных подходов стран Европы, Северной Америки и Азиатско-Тихоокеанского региона с позиций устойчивого проектирования. Результаты: установлено, что международные нормативные системы предусматривают количественное проектирование долговечности с использованием математических моделей карбонизации и хлоридной диффузии, вероятностных методов оценки надежности и цифровых технологий управления жизненным циклом мостов. Нормативные документы стран АТР демонстрируют активный переход к Performance-Based Design и интеграции экологических показателей в проектные процедуры. Выявлено, что действующие нормативы СП 35.13330.2011 и ШНК 2.05.03- 22 обеспечивают нормативную долговечность конструкций, однако не содержат формализованных моделей прогнозирования ресурса и количественной оценки экологической эффективности. Обоснованы направления совершенствования отечественной нормативной базы на основе принципов Service Life Design и Life-Cycle Design. Практическая значимость: полученные результаты могут быть использованы при актуализации национальных нормативных документов, разработке методик расчета долговечности железобетонных мостов и внедрении устойчивых проектных решений. Предложенные подходы способствуют повышению достоверности прогноза ресурса, оптимизации затрат жизненного цикла и снижению экологического воздействия мостовых сооружений.</p>

    <p>Objective: to perform an extended comparative analysis of the modern regulatory framework governing the design of reinforced concrete bridges considering environmental impact, including EN 206 and Eurocode 2, AASHTO LRFD, national standards of Russia and Uzbekistan, as well as regulatory documents of the Asia-Pacific region (Japan, China, India, Australia, and New Zealand). The study aims to identify the specific features of methodological approaches to ensuring bridge durability and to determine directions for improving regulatory requirements under the transition to service life design and life-cycle management of structures. Methods: a comparative analysis of international and national regulatory documents was conducted based on criteria including environmental exposure consideration, design service life specification, application of degradation models, probabilistic reliability assessment, and integration of Life-Cycle Cost (LCC) and Life-Cycle Assessment (LCA) methods. A systematic analysis of regulatory approaches in Europe, North America, and the Asia-Pacific region was carried out from the perspective of sustainable design. Results: it was established that international regulatory systems provide for quantitative durability design using mathematical models of carbonation and chloride diffusion, probabilistic reliability methods, and digital technologies for bridge life-cycle management. Regulatory documents of the Asia-Pacific region demonstrate an active transition toward performance-based design and the integration of environmental indicators into design procedures. It was found that the current Russian standard SP 35.13330.2011 and the Uzbek standard SHNK 2.05.03-22 ensure normative durability of structures; however, they do not include formalized service life prediction models or quantitative environmental performance assessment. Directions for improving the national regulatory framework are substantiated based on the principles of Service Life Design and Life-Cycle Design. Practical significance: the obtained results may be applied in updating national regulatory documents, developing durability assessment methodologies for reinforced concrete bridges, and implementing sustainable design solutions. The proposed approaches improve the reliability of service life prediction, optimize life-cycle costs, and reduce the environmental impact of bridge structures.</p>
