Такие решения позволят сооружению воспринимать инерционные силы сейсмического воздействия, сохраняя при этом его несущую способность в течение всего периода эксплуатации. Для решения этой проблемы предлагается использовать стальные рамные узлы, которые можно применять как для всего каркаса здания в целом, так и на отдельных этажах, для создания эффекта «гибкого этажа». Авторами изучены статьи, книги и патенты из России, США, Японии, Китая и Ирана, проведен анализ факторов, снижающих надежность и эксплуатационные характеристики узлов. Выявлено, что главным таким фактором является сварное соединение, которое используется для крепления ригелей к колоннам, поперечных ребер в теле колонны и формированию коробчатого сечения колонны из листов, уголков или швеллеров. Учитывая тот факт, что на территории России присутствуют сейсмоопасные зоны с пониженными температурами, надежность сварного соединения снижается еще сильнее. В то же время, узлы без сварного соединения требуют специальных литых деталей или устройств, что снижает их доступность. В связи с этим ставится задача по разработке новых оригинальных конструктивных решений узлов, удовлетворяющим требованиям надежности и доступности.</p></abstract><trans-abstract xml:lang="en"><p>The paper analyzes the existing construction solutions of steel frames with a box-section column and an I-beam crossbar in order to use them in earthquake zones, including areas with low temperatures. Such solutions will allow the structure to accept the seismic inertial forces, while maintaining its bearing capacity throughout the entire period of operation. In order to solve this problem, the study proposes to use steel frame joints, which can be used both for the entire frame of the building and on individual floors, thereby creating a “flexible story” effect. The authors studied articles, books and patents issued in Russia, the United States, Japan, China and Iran, analyzed the factors that reduce the reliability and performance characteristics of the joints. The main factor consists in a welded joint, which is used to attach the crossbars to the columns, transverse ribs in the column body, and to form the box section of the column from sheets, angles or channels. The reliability of the welded joint is reduced even more under conditions of seismic zones with low temperatures in Russia. However, units without welded joints require special cast parts or structures, thereby reducing their availability. In this regard, the task consists in developing new original construction solutions for joints that meet the requirements of reliability and availability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стальной рамный узел</kwd><kwd>коробчатое сечение</kwd><kwd>сейсмика</kwd><kwd>низкие температуры</kwd><kwd>сварной шов</kwd><kwd>«гибкий этаж»</kwd></kwd-group><kwd-group xml:lang="en"><kwd>joint for steel frame</kwd><kwd>box-section column</kwd><kwd>seismic</kwd><kwd>low temperature</kwd><kwd>weld</kwd><kwd>soft story</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">Поляков В.С., Килимник Л.Ш., Черкашин А.В.
