Protection of buildings and structures against progressive collapse within the framework of legislative and regulatory requirements

At present, the current legislative and regulatory documents do not contain a clear and unambiguous answer to the question, what buildings and structures should be designed resistant to progressive collapse. In this regard, the analysis of the legal and regulatory requirements of the need for calculations to prevent the progressive collapse of buildings and structures due to hypothetical or suspected local destruction is presented. The main legislative requirements of technical regulation in the field of ensuring the mechanical safety of buildings and structures, as well as the requirements of regulatory documents regarding the design of the protection of building and structures against progressive collapse are considered. The analysis of the fundamental principles features of the calculation for the structural protection against progressive collapse is given. Some issues discussed by the professional community in the direction of possible ways of solving the actual problems of the presented problem are considered. The conclusion is made about the need for further dialogue of the professional community on the development of a common position on the protection of buildings and structures from progressive collapse, which should be reflected in the legislative and regulatory requirements.
