Причина кручения заключается в появлении эксцентриситета приложения горизонтальной нагрузки между центром масс и центром жесткостей. Вертикальные несущие элементы панельных зданий соединяются в пространственную систему различными связями сдвига. Податливость плотных сварных связей в нелинейной постановке базируется на экспериментальных данных на действие сдвигающих усилий. Принимая во внимание, что податливость зависит не только от сдвигающего воздействия, но и является функцией высоты здания, необходима полная диаграмма деформирования рассматриваемой плотной связи. Влияние крутящего воздействия на податливость плотных связей ранее не рассматривалось. В данной работе представлена конечно-элементная модель, реализованная в программном комплексе ANSYS фрагмента панельного здания. Фрагмент здания определялся из условия проведения дальнейших экспериментальных исследований по прочности и деформативности сварного стыка, соединяющего две вертикальные несущие конструкции. Численным моделированием определено напряженно-деформированное состояние вертикального плотного стыка панельных зданий при действии сдвига и кручения. Шаговое нагружение исследуемого образца велось в вертикальной и горизонтальной плоскости. История нагружения принята в первом приближении самая простая - пропорциональная. Определена несущая способность и деформативность стыка при действии сдвига и кручения. Получены диаграммы деформирования плотного стыка. Определена предельная нагрузка, при которой соединение превращается в шарнир. Крутящее воздействие приводит к увеличению податливости плотной связи. Результаты проведенного анализа могут быть использованы при диаграммном методе расчета железобетонных конструкций панельных зданий подверженных кручению.</p></abstract><trans-abstract xml:lang="en"><p>Under the action of horizontal wind and seismic loads, torsion occurs in asymmetric load-bearing systems of multi-storey buildings. The reason for torsion is the appearance of an eccentricity between the center of mass and the center of rigidity of the application of a horizontal load. Vertical loadbearing elements of panel buildings are connected into a spatial system by various shear bonds. The deformability of welded butt joints in a nonlinear formulation is based on experimental data on the action of shear forces. Considering that the deformability of a shear connection depends not only on the shear force, but is also a function of all forces and stresses along the height of a multi-story building, a complete deformation diagram of the shear connections under consideration is necessary. The influence of torsional action on the deformability of shear bonds has not been previously considered. This paper presents a finite element model realized in the ANSYS software package of a fragment of a panel building. The building fragment was determined under the condition of further experimental studies on the strength and deformability of the welded joint connecting two vertical load-bearing structures.</p><p>Numerical simulation determined the stress-strain state of a vertical dense joint of panel buildings under the action of shear and torsion. Step loading of the investigated fragment was carried out in the vertical and horizontal plane. The loading history adopted in the first approximation is the simplest – proportional. The bearing capacity and deformability of the joint under the action of shear and torsion are determined. Diagrams of the deformation of a dense joint are obtained. The ultimate load at which the joint becomes a hinge is determined. The torsional effect leads to an increase in the deformability of the dense bond. The results of the analysis can be used in the diagrammatic method of calculation of reinforced concrete structures of panel buildings subject to torsion.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>панельные здания</kwd><kwd>кручение</kwd><kwd>центр жесткостей</kwd><kwd>центр масс</kwd><kwd>несущая способность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>panel buildings</kwd><kwd>torsion</kwd><kwd>center of stiffness</kwd><kwd>center of mass</kwd><kwd>load capacity</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">Дроздов П.
