Исследование направлено на развитие методов оценки и анализа надежности элементов строительных конструкций в практических задачах, когда статистическая информация о случайных величинах может быть неполной или ограниченной. В таких случаях затруднительно выявить конкретный вид точной функции распределения случайной величины или дать точную оценку параметру распределения, так как возникает необходимость учесть эпистемологическую неопределенность, помимо алеаторной.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для эффективного моделирования двух видов неопределенностей предлагается использовать граничные функции распределения случайной величины, которые формируют р-блок (probability box). Р-блоки позволяют учесть как неопределенность, вызванную естественной (природной) изменчивостью случайных параметров, так и неопределенность, вызванную недостатком знаний о случайной величине (количество контрольных образцов, точность измерительных приборов и т.д.).</p></sec><sec><title>Результаты</title><p>Результаты. Предложен новый вид р-блока, построенный на неравенстве Дворецкого – Кифера – Вулфовица и неравенстве П.Л. Чебышёва, что позволяет сформировать две граничные функции распределения по данным выборочной совокупности. На численном примере показан подход к арифметическим операциям с р-блоками, которые дают возможность привести сложные математические модели к более простым и оценить вероятность безотказной работы в интервальной форме. Разница между аналитическим и численным решением по примеру составила 0,9 %.</p></sec><sec><title>Выводы</title><p>Выводы. Граничные функции распределения позволяют более осторожно и достоверно подойти к анализу надежности строительных конструкций. Результат оценки надежности с использованием р-блоков представлен в интервальной форме. Если интервал получается слишком широким и неинформативным, то необходимо повысить количество или качество статистической информации или увеличить сечения элементов строительных конструкций для достижения нижней границы интервала требуемого уровня надежности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The research is aimed at the development of methods for assessing and analyzing the structural reliability of elements of building structures in practical tasks when statistical data about random variables may be incomplete or limited. In such cases, it is difficult to identify the specific type of the exact cumulative distribution function of a random variable or to give an accurate estimate of the distribution parameter, because there is a need to take into account epistemic uncertainty in addition to aleatory uncertainty.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. For effective modelling of two types of uncertainties, it is proposed to use boundary distribution functions of a random variable that form a p-box (probability box). P-boxes take into account both types of uncertainty: caused by natural variability of random parameters and uncertainty caused by lack of knowledge about the random variable (number of control samples, accuracy of measuring instruments, etc.).</p></sec><sec><title>Results</title><p>Results. The paper proposes a new type of p-box based on the Dvoretzky – Kiefer – Wolfowitz inequality and Chebyshev’s inequality, which form two boundary distribution functions based on the sample population data. The numerical example shows the approach to arithmetic operations with p-boxes, which make it possible to bring complex mathematical models to simpler ones and estimate the failure probability in an interval form. The difference between the analytical and numerical solution for the example is 0.9 %.</p></sec><sec><title>Conclusions</title><p>Conclusions. Boundary distribution functions form a more cautious and reliable approach to the structural reliability analysis. The result of reliability assessment using p-boxes is presented in an interval form. If the interval turns out to be too wide and uninformative, then it is necessary to increase the quantity or quality of statistical data or to increase the cross-sections of structural elements to achieve the lower limit of the interval of the required reliability level.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>надежность</kwd><kwd>вероятностное проектирование</kwd><kwd>р-блоки</kwd><kwd>вероятность отказа</kwd><kwd>критерий Колмогорова – Смирнова</kwd><kwd>неопределенность</kwd><kwd>безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reliability</kwd><kwd>probabilistic design</kwd><kwd>p-boxes</kwd><kwd>failure probability</kwd><kwd>Kolmogorov – Smirnov criterion</kwd><kwd>uncertainty</kwd><kwd>safety</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность рецензентам, редакционной коллегии и сотрудникам редакции за обсуждение и подготовку к публикации настоящей работы.
