Как результат достоверно оценить напряженно-деформированное состояние данных конструкций особенно при динамических нагружениях практически невозможно. Для проведения экспериментальных исследований было изготовлено 37 железобетонных образцов – колонн квадратного сечения размерами 100х100 мм, высотой 700 мм. В железобетонных образцах создавались локальные коррозионные повреждения бетона и арматуры при этом для ускоренного корродирования элементов в качестве агрессора использовался концентрированный раствор (37%) соляной кислоты (HCL). В статье описаны экспериментальные исследования изменения динамических свойств внецентренно сжатых коррозионно-поврежденных железобетонных элементов. На основании данных тензометрии установлено, что коррозионные повреждения приводят к уменьшению высоты сжатой зоны бетона за счет уменьшения сечения растянутой арматуры, а также отсутствия совместной работы арматуры с бетоном. По данным тензометрии получены деформаций внецентренно сжатых коррозионно-поврежденных и неповрежденных сечений, которые показали, что эпюры деформаций принципиально различаются очертанием. Полученные в результате натурного исследования деформации арматуры и бетона, позволили оценить напряженно- деформированное состояние поврежденных и не поврежденных коррозией конструкций по параметру Ne-1/r (кривизна). Установлено влияние коррозионных повреждений на характер разрушения внецентренно сжатых элементов.</p></abstract><trans-abstract xml:lang="en"><p>There are practically no results of experimental studies of elements made of compressed reinforced concrete damaged by corrosion in the scientific literature. As a result, it is almost impossible to reliably assess the state of deformation-deformation of these structures, especially under dynamic loads. For experimental studies, 37 samples of reinforced concrete were made-columns of square cross-section with dimensions of 100x100 mm, height of 700 mm. Local corrosion damages of concrete and reinforcement were created in reinforced concrete samples, while a concentrated (37%) hydrochloric acid (HCL) solution was used as an aggressor to accelerate the corrosion of elements. The article describes experimental studies on changing the dynamic properties of reinforced concrete elements that undergo corrosion during eccentrically compression. Based on strain gauge data, it was found that corrosion damage leads to a decrease in the height of the compressed concrete section by reducing the cross-section of the stretched reinforcing bars, as well as to the lack of joint work of reinforcing bars with concrete. According to strain measurement data, deformations of uncompressed and undamaged sections were obtained, which showed that the deformation diagrams fundamentally differ in their contour. The results obtained as a result of the study of the nature of deformation of reinforcement and concrete allowed us to assess the state of deformation stress of damaged and non- corroded structures according to the parameter Ne-1/r (curvature). The effect of corrosion damage on the nature of destruction of eccentrically compressed elements has been established.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внецентренно сжатые элементы</kwd><kwd>коррозионные повреждения</kwd><kwd>динамическое нагружение</kwd><kwd>экспериментальные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>eccentrically compressed elements</kwd><kwd>corrosion damage</kwd><kwd>dynamic loading</kwd><kwd>experimental studies</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">Тамразян А.Г.
