This article is devoted to the analysis of ways to protect the bridge structure from external influences. The author analyzes these methods on the basis of publicly available data from companies engaged in the production of structures that prevent external influences, as well as on the basis of modern regulatory documents. The article presents such methods of protection as: deformation seams, support parts, dampers of various modifications and vibration dampers of shrouds. To choose the optimal method, both from the economic side and from the technical side, it is necessary to make verification calculations for static, dynamic and seismic effects, study the geological characteristics of the construction site, conduct mandatory tests of the structures used, as well as use regulatory documents and guidelines for testing and using seismic isolation devices. Also, the author of the article emphasizes that it is important to study ways to protect bridge structures not only in domestic practice, but also in foreign practice.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> bridge construction; expansion joint; bearing part; damping device; energy dissipation; active seismic protection systems; external influence<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Berlov Stanislav Anatolievich Industrial university of Tyumen, Tyumen, Russia E-mail: berlovstanislav@yandex.ru Ovchinnikov Ilya Igorevich Industrial university of Tyumen, Tyumen, Russia Yuri Gagarin state technical university of Saratov, Saratov, Russia E-mail: bridgeart@mail.ru Abstract.
