В настоящее время основные закономерности нелинейного динамического деформирования железобетона при одноосном напряженном состоянии достаточно подробно рассмотрены в теоретическом плане при наличии широкого спектра экспериментальных исследований. Свойства бетона в условиях двухосного напряженно-деформированного состояния при кратковременном динамическом нагружении изучены в меньшей степени. В настоящей работе предложен критерий динамической прочности бетона, учитывающий изменение коэффициента динамического упрочнения бетона в зависимости от вида напряженного состояния, соотношения главных напряжений σ3 ⁄ σ1 и скорости деформирования έ.</p></abstract><trans-abstract xml:lang="en"><p>Modern calculation models must take into account the dynamic deformation of reinforced concrete. Currently, the main regularities of nonlinear dynamic deformation of reinforced concrete under uniaxial stress state are theoretically analyzed in detail along with a wide range of experimental studies. Properties of concrete under plane stress -strain state and dynamic loading are examined to a lesser extent. This paper proposes the dynamic strength condition for the concrete strength which allows for changing the strain -hardening coefficient of concrete depending on the type of stress -strain state, the ratio of the primary stresses and the deformation rate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>критерий прочности бетона</kwd><kwd>плоское напряженное состояние</kwd><kwd>двухосное сжатие</kwd><kwd>растяжение-сжатие</kwd><kwd>кратковременная динамическая нагрузка</kwd><kwd>напряжения</kwd><kwd>прочность бетона</kwd><kwd>экспериментальные данные</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concrete strength condition</kwd><kwd>plane stress-strain state</kwd><kwd>biaxial compression</kwd><kwd>expansion-compression</kwd><kwd>dynamic load</kwd><kwd>stress</kwd><kwd>concrete strength</kwd><kwd>experimental data</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">Карпенко Н.И., Круглов В.М., Соловьев Л.Ю.
