Progressive collapse - or, in particular, an understanding of the mechanics of this phenomenon and the development of ways to consider it in the framework of structural design - can be regarded as a relatively new topic in building science. The article describes the background to the emergence of this topic, ranging from local examples of the collapse of buildings and ending with the well-known collapse of the World Trade Center. Analyzed the latest world research in this area and revealed inconsistencies in the requirements of regulatory documentation and the real work of the building frame in case of progressive collapse

Keywords: progressive collapse, durability, steel frame, multi-storey buildings, connections stiffness, ductility
