Определение значения параметрической нагрузки, при которой в наиболее напряженном пространственном сечении при рассматриваемом режиме нагружения наступает один из критериев особого предельного состояния получено из системы канонических уравнений неординарного варианта смешанного метода. В соответствии с этим вариантом смешанного метода, решение задачи построено таким образом, когда первоначальная исходная система подконструкции рамы описывается шарнирно-стержневой моделью, в которой места возможного выключения связей заменяют сложными шарнирами и соответственно неизвестными угловыми и линейными связями. путем выполнения численных исследований и сравнением с экспериментальными данными дана оценка эффективности и достоверности разработанной методики. Показано, что при принятых исходных гипотезах предложенная методика расчета живучести рам со сложнонапряженными элементами удовлетворительно описывает процесс их деформирования и разрушения при рассматриваемых воздействиях.</p></abstract><trans-abstract xml:lang="en"><p>On the energy basis, using the diagrammatic method, the solution of the problem of determining the survivability parameter of the reinforced concrete frame structure of a multistory building with complex-stressed elements under static-dynamic deformation caused by a special impact is obtained. Determination of the parametric load value, at which in the most stressed spatial section at the considered loading mode one of the criteria of the special limit state comes from the system of canonical equations of the extraordinary version of the mixed method. Comparison of the experimental and design survivability parameters gives an assessment of the efficiency and reliability of the proposed design dependencies. It has been shown that with the adopted initial hypotheses, the proposed method for calculating the survivability of frames with complex stressed elements satisfactorily describes the process of their deformation and destruction under the considered impacts.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железобетонная рама</kwd><kwd>сложное напряженное состояние</kwd><kwd>экспериментально-теоретические исследования</kwd><kwd>особое воздействие</kwd><kwd>расчетная модель</kwd><kwd>параметр живучести</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforced concrete frame</kwd><kwd>complex stress state</kwd><kwd>experimental and theoretical studies</kwd><kwd>special impact</kwd><kwd>calculation model</kwd><kwd>survivability parameter</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">Колчунов В.И.
