Annotation: The article examines the history of the problem of buildings and structures assessment of resistance to progressive collapse. The main prerequisites for the beginning of the study on the prevention of progressive collapse in Russia, the United States and the European Union countries have been identified. The analysis of pilot research of fragments of building structures for progressive collapse has been carried out. Foreign and domestic approaches to the methods of pilot research of fragments of building structures are considered, and their main features are revealed. Based on the analysis of recent studies and publications, it has been concluded that with an increase in static uncertainty and structural instability, resistance to progressive collapse increases, and dynamic overloading occurs in the surviving structural elements with a sudden application of load. It is also noted that dynamic overloading of the entire system is more dangerous than switching off the carrier element. Theoretical and experimental studies of the protection of structures from progressive collapse are necessary for a more detailed study of the behavior of structures under the influence of special loads.
Keywords: progressive collapse, emergency impact, local collapse, stress-strain state.
