Проанализированы существующие вероятностные модели базисных (основных) переменных, входящих в функции нагрузок и сопротивлений. Получены и интегрированы в виде базисной переменной при вероятностном моделировании статистические параметры неопределенности модели сопротивления.Выполнено вероятностное моделирование по методу Монте-Карло конструктивных систем из сборного и монолитного железобетона, запроектированных по действующим нормам Республики Беларусь. Определены функции предельного состояния конструктивной системы в особой расчетной ситуации при внезапном удалении центральной колонны первого этажа. В результате для рассматриваемых конструктивных систем получены значения вероятностей отказа и соответствующих индексов надежности.</p></abstract><trans-abstract xml:lang="en"><p>With the help of probabilistic modeling, the issues related to the assessment of the robustness of structural systems made of prefabricated and monolithic reinforced concrete in an accidental design situation are considered.The paper considers the concept of analyzing the reliability of structural systems and differentiating risks in accidental design situations. The existing probabilistic models of the basic variables included in the functions of loads and resistances are analyzed. Statistical parameters of the uncertainty of the resistance model are obtained and integrated in the form of a basic variable with probability modeling.Probabilistic modeling of structural systems made of precast and monolithic reinforced concrete, designed according to the current standards of the Republic of Belarus, was carried out using the Monte Carlo method. The functions of the limiting state of the structural system in an accidental design situation with the sudden removal of the central column of the first floor are determined. As a result, values of failure probabilities and corresponding reliability indices were obtained for the considered constructive systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>живучесть</kwd><kwd>вероятностный подход</kwd><kwd>вероятность отказа</kwd><kwd>индекс надежности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>robustness</kwd><kwd>probabilistic approach</kwd><kwd>probability of failure</kwd><kwd>reliability index</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">СН 2.01.01-2022.
