В настоящее время основным методом исследования таких конструкций на возникновение явлений аэроупругой неустойчивости является экспериментальное моделирование в аэродинамических трубах.</p><p>Экспериментальное моделирование основано на предположении о неизменности формы поперечного сечения моста с течением времени. Очевидно, что такое предложение не может быть верным, поскольку наличие транспортных средств на мостовой конструкции изменяет профиль поперечного сечения моста. В связи с этим крайне важно выяснить, является ли обоснованным игнорирование изменения профиля поперечного сечения мостов из-за наличия транспортного потока. Настоящее исследование направлено на то, чтобы путем экспериментального моделирования в аэродинамических трубах получить представление о влиянии на аэродинамическую устойчивость моста изменений его поперечного сечения из-за наличия трафика.</p></abstract><trans-abstract xml:lang="en"><p>Under certain conditions, wind effects on long-span bridges can cause aeroelastic instability phenomena. Currently, the main method for studying such structures for occurrence of aeroelastic instability phenomena is experimental modelling in wind tunnels.</p><p>Experimental modelling is usually based on the assumption that the cross-sectional shape of the bridge remains unchanged over time. Obviously, such a proposal cannot be true, since the presence of vehicles on the bridge structure changes the crosssectional profile of the bridge. In this regard, it is extremely important to find out whether it is justified to ignore the change in the crosssectional profile of bridges due to the presence of traffic. The present study is aimed at obtaining, using experimental modelling in wind tunnels, a notion of the effect of changes in the cross-section of the bridge due to the presence of traffic on its aerodynamic stability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>транспортная инфраструктура</kwd><kwd>большепролетные мосты</kwd><kwd>устойчивость мостов</kwd><kwd>трафик</kwd><kwd>ветровые воздействия</kwd><kwd>аэродинамические трубы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transport infrastructure</kwd><kwd>long-span bridges</kwd><kwd>bridge stability</kwd><kwd>traffic</kwd><kwd>wind effects</kwd><kwd>wind tunnels</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">данная работа была поддержана грантом 2024 года на проведение фундаментальных и прикладных научных исследований (НИР/НИОКР) научными коллективами НИУ МГСУ, проект № 01–392/130.</funding-statement><funding-statement xml:lang="en">this work was supported by a 2024 grant for fundamental and applied scientific research (R&amp;D) for research teams of the National Research Moscow State University of Civil Engineering, project No. 01–392/130.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jain, A., Jones, N.
