| description | The article presents the results of the study of the survivability of a multi-storey building in the event of an emergency failure of a load-bearing element of precast reinforced concrete floor. Carrying out of such researches is stipulated by norms of designing with the purpose of maintenance of safety of buildings and constructions and exception of progressive destruction of designs. In the course of the research, the analysis of possible failures of an individual slab of precast flooring was carried out, the impact force of the falling structure on the below-mentioned overlap was taken into account, taking into account the dynamic factor and the possibility of progressive destruction of the building was verified. A concrete case of a failure of a slab is considered as a result of emergency collapse of the cornice part of the external brick wall of a 5-storey residential building. The necessity of reserving the strength of the structure of overlap from hollow-core slabs is revealed. The backup function is performed by interplate connections from concrete keys, which are usually provided to ensure the rigidity of the discs of the floors and the stability of the building under the action of horizontal loads. The load-bearing capacity of typical concrete keys has not been evaluated by the method of Russian design standards under the effect of overlapping the emergency load with the intensity recommended by European standards for the design of buildings and structures. In the conclusions, the expediency of using structural ties of prefabricated ceilings with the purpose of excluding the progressive collapse of multi-storey buildings was noted. |
