The modern experimental studies review of the resistance of the most common steel and steel-concrete building structures in emergency conditions is performed. The main directions of experimental design are revealed under certain types of special influences that affect the mechanical safety of structures. An overview of the experimental studies of steel and steelconcrete lamellar-structural elements survivability in local damage to columns, described in the modern scientific literature is presented. Tests of lamellar and light steel thin-walled structures on the effect of cyclic loading are described. Data on the limit static loads of beams and spatial frame systems are given. Attention to testing of structures for combined impact and explosive effects is paid. Photos and diagrams of laboratory samples and objects are given. As a result of the review, a conclusion is made about the prospects for further studies of the survivability of steel structures under emergency actions. It is noted, that now there is a need to expand the nomenclature of standardized types of emergency actions. That will allow to more effectively carrying out a complex of preventive measures that let us to increase the mechanical safety of structures and minimize potential risks of material and social losses in the event of emergencies.

В статье выполнен обзор современных экспериментальных исследований силового сопротивления наиболее распространенных стальных и сталебетонных строительных конструкций в запредельных состояниях. Выявлены основные направления постановок экспериментов при некоторых типах особых воздействий, влияющих на обеспечение механической безопасности сооружений. Рассмотрены изложенные в современной научной литературе экспериментальные исследования живучести стальных и сталебетонных пластинчато-стержневых элементов сооружений при локальных повреждениях колонн. Описываются испытания пластинчатых и легких стальных тонкостенных конструкций на действие циклической знакопеременной нагрузки. Приводятся данные по предельным статическим нагружениям балок и пространственных рамных систем. Уделено внимание испытаниям конструкций на комбинированные ударные и взрывные воздействия. Исследования иллюстрируются фотографиями и схемами лабораторных образцов и натурных объектов. По результатам обзора делается вывод о перспективах дальнейших исследований живучести стальных конструкций при запроектных воздействиях. Отмечается необходимость расширения номенклатуры нормируемых типов запроектных воздействий, что позволит более эффективно выполнять комплекс превентивных мероприятий, обеспечивающих повышенную механическую безопасность сооружений и минимизацию потенциальных рисков материальных и социальных потерь при возникновении аварийных ситуаций.
