In this connection, the purpose of the study was an experimental assessment of the deformation parameters in the complexly stressed elements of reinforced concrete frames under special impact in the form of a sudden column removal. Experimental studies were carried out for two frames, one of which was tested when removing the middle column, the second - when removing the extreme. Experimental two-span structures of reinforced concrete frames are designed with three floors in height, reinforcement was made with spatial reinforcing cages that provide resistance to torsion with bending. The results of experimental and theoretical studies of reinforced concrete frame structures under special influences and an assessment of displacements, cracking and destruction of the considered complex-stressed structural elements under such influences are presented. It is established that the type of stress state, the formation and width of crack opening significantly affect the dissipative properties of the structural system.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Экспериментальное определение параметров силового сопротивления железобетонных конструкций, направленное на их защиту от аварийных запроектных воздействий, является важным направлением в повышении механической безопасности зданий и сооружений в условиях современных вызовов. В связи с этим целью исследования стала экспериментальная оценка параметров деформирования в сложнонапряженных элементах железобетонных рам при особых аварийных воздействиях, вызванных внезапным удалением одного из несущих элементов. Экспериментальные исследования выполнены для двух железобетонных рам, одна из которых испытана при мгновенном удалении средней колонны, а вторая - при удалении крайней. Конструкции рам запроектированы двухпролетными с тремя этажами по высоте и с использованием пространственных арматурных каркасов, обеспечивающих сопротивление кручению с изгибом. Приведены результаты экспериментально-теоретических исследований конструкций железобетонных рам в запредельных состояниях при особых воздействиях и проведена оценка перемещений, трещинообразования и разрушения рассматриваемых сложнонапряженных элементов конструкций при таких воздействиях. Установлено, что вид напряженного состояния, картина образования, раскрытие и развитие трещин существенно влияют на параметры деформирования и диссипативные свойства элементов конструктивной системы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>experimental research</kwd><kwd>complex-stressed reinforced concrete</kwd><kwd>special impact</kwd><kwd>survivability</kwd><kwd>resistance</kwd><kwd>progressive collapse</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>экспериментальные исследования</kwd><kwd>сложнонапряженный железобетон</kwd><kwd>особые воздействия</kwd><kwd>живучесть</kwd><kwd>защита</kwd><kwd>прогрессирующее обрушение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Alternate path analysis &amp; design guidelines for progressive collapse resistance.
