    Abstract. A computational model of stability of a multi-storey frame building on the action of spacer forces arising in case of emergency failure of one of the columns with the condition of transition of the system of bending elements of overlapping in the suspension system is proposed. The calculated emergency situation is considered when the failure of the column is associated with the punching of the monolithic slab of the overlap. The results of the calculation in a situation similar to what happened in Korea, when the building of the shopping center collapsed in a matter of seconds, taking hundreds of lives, are presented. It is shown that due to the insufficient stability of the frame, the progressive collapse of this building due to the failure of one node of the column interface with the ceiling was inevitable. A variant of structural sustainability of the frame building by the installation of calculated connections in the extreme spans of each floor or through the floor, starting from the top, is given. In this case, the failure of any columns can occur without progressive collapse.
    Key words: frame building, flat slab floor, column failure, punching, survivability, progressive collapse, stability, safety, suspension system.
