The paper provides summary the problems of estimating high-rise buildings to a progressive collapse. The analysis of the structure of the technique for calculating the skeleton of the building for a progressive collapse is performed. Recommendations are given on the properties of reinforced concrete carcass elements for emergency actions. An imitation simulation of the emergency response using the finite element method in calculating the building frame for progressive collapse was proposed; Modeling and investigation of the stress-strain state of individual elements of the building's frame for the effect of explosive loading; modeling and investigation of resistance to the progressive collapse of the skeleton of a high-rise building; development of constructive solutions to achieve resistance to progressive collapse.

Keywords: progressive collapse, special action, finite element method, building frame modeling, stress-strain state
