PROTECTION OF LARGE PANEL BUILDINGS AGAINST PROGRESSIVE COLLAPSE

Abstract

With the large panel buildings being widely used, effective protection of buildings against the destructive effects of extraordinary loads becomes an important issue. Therefore, the article delves into the history of developing standards that regulate design basics of buildings made of large-scale elements.

The article deals with characteristic properties such as spatial stiffness by using a system of rigid transverse and longitudinal walls. The author emphasizes that a characteristic feature of the design of large panel buildings is the presence of monolithic joints between prefabricated elements in the ceiling and wall slabs. The article identifies the components that play an important role in ensuring sufficient reliability of large panel system buildings.

The article stipulates methods of accounting for accidental loads in designing large panel system buildings and covers application methods. The article covers the guidelines for protecting large panel buildings against progressive collapse.

The authors outline that the local destruction of a load-bearing wall in the zone adjacent to the outer edge is extremely dangerous due to a progressive collapse, and that is why it is important to take into account progressive collapse in structural design.

The article contains basic design recommendations for protecting large-panel buildings against the effects of extraordinary loads.

In conclusion, the authors opine that the methodology of protecting large panel buildings against the effects of a progressive collapse may be used for assessing the state of a structure damaged due to warfare.

In the case of war damage to large-panel buildings occurring in Ukraine, due to the extent of the destruction, the article recommends developing procedures aimed at reliability assessment with partial use of the methods described in the article. On top of that, the catalog of strengthening solutions for each large panel system should be developed and available in case if reconstruction is needed.
