Недостаточность нормативной базы по расчету узлов с вклеенными соединениями приводит к разобщенности методик расчета, используемых инженерами-проектировщиками. Предложена методика конструирования и расчета конькового узла деревянных конструкций с вклеенными шайбами.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Выполнены инженерный расчет конькового узла и его элементов, моделирование и расчет рассматриваемого соединения, а также анализ возможности его применения на примере существующего здания, рассчитанного в ПК SCAD.</p></sec><sec><title>Результаты</title><p>Результаты. Разработано конструктивное решение жесткого узла нового типа на основании применения вклеиваемых в древесину стальных шайб. Проведены численно-теоретический анализ каждого элемента соединения на усилия, передаваемые соседними конструкциями; оценка численного порядка воспринимаемого предлагаемой конструкцией изгибающего момента. Несущая способность предлагаемого решения исключает податливость и повышает прочность всего соединения.</p></sec><sec><title>Выводы</title><p>Выводы. Предлагаемый узел имеет меньший вес по сравнению с аналогичными на вклеенных стержнях. Новая конструкция узла поможет проектировщикам расширить вариативность методов конструирования узлов, предложенных в нормативной базе, а также использовать новую конструкцию соединений взамен типовых решений. Рассматриваемый метод расчета узлового соединения способен улучшить надежность, повысить экономическую эффективность всей конструкции в целом. Возможность применения предлагаемого узла подтверждена методами численного моделирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. In order to give geometric immutability to load-bearing structures that accept horizontal loads from the wind, it is necessary to introduce rigid nodes into the design scheme. The insufficiency of the regulatory framework for calculating nodes with glued joints leads to a separation of calculations from company to company. This paper proposes a method for designing and calculating a ridge assembly of wooden structures with glued washers.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Engineering calculation of the ridge node and its elements, modelling and calculation of the considered connection, as well as analysis of the possibility of its application on the example of an existing building, calculated in the SCAD software.</p></sec><sec><title>Results</title><p>Results. A constructive solution for a new type of rigid assembly was developed based on the use of steel washers glued into wood. A numerical and theoretical analysis of each element of the joint for the forces transmitted by neighboring structures is carried out. Estimation of the numerical order of the bending moment perceived by the proposed design. The bearing capacity of the proposed solution eliminates ductility and increases the strength of the entire joint.</p></sec><sec><title>Conclusions</title><p>Conclusions. The proposed assembly is lighter than its counterpart on glued rods, and the lack of a regulatory framework for such structures forces designers to make standard decisions. The proposed method for calculating the nodal connection can improve reliability, as well as increase the economic efficiency of the entire structure. The possibility of using the proposed node has been confirmed by numerical modelling methods.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>стропильная конструкция</kwd><kwd>узловые соединения</kwd><kwd>жесткий узел</kwd><kwd>вклеенные шайбы</kwd><kwd>несущая способность</kwd><kwd>деревянные конструкции</kwd><kwd>жесткий стык</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rafter structure</kwd><kwd>nodal joints</kwd><kwd>rigid assembly</kwd><kwd>glued washers</kwd><kwd>load-bearing capacity</kwd><kwd>wooden structures</kwd><kwd>rigid joint</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">Azzi Z., Al Sayegh H., Metwally O., Eissa M.
