Pushover analysis is a nonlinear static method of analysis of seismic resistance of buildings and structures, in which the seismic load is gradually increasing to determine the pattern of distribution of forces in the structural elements of the building, as well as the nature of the oscillations of its upper point. The result of the calculation is the family of diagrams at different levels of the seismic load. In calculations for the progressive collapse, the method is applicable: for the preliminary determination of the "weak points" of the structure; to calculate the seismic stability of the model obtained according to the results of calculating the progressive collapse
