ANALYSIS OF CONSTRUCTIVE SOLUTIONS OF THE EXISTING BUILDINGS OF THE HOUSING FUND OF THE KHARKIV CITY ON THE SUBJECT OF THEIR PERFORMANCE AS A CONSEQUENCE OF THE INFLUENCE OF COMBAT ACTIONS

Abstract

The article examines the main structural solutions of existing residential buildings inthe city of Kharkiv and analyzes their working capacity from the point of view of resistance toexplosive effects and, as a result, progressive collapse. It is known that progressive collapse ischaracteristic of extreme (emergency) cases, when due to destruction of a responsible element of thestructure as a result of a gas explosion, ammunition bursts, climatic cataclysms, transport collapses,etc a part of the building or the entire structure collapses. It is noted that every year, the interest ofthe world scientific community in the issues of progressive collapse is growing, because,unfortunately, the number of cases of avalanche-like collapse of buildings of various types isincreasing. This was facilitated by already known cases of collapses of various objects, such as theRonan Point residential building (Great Britain) in 1968 or the buildings of the World Trade Center(USA) in 2011, or the very recent case of the collapse of a residential building in Surfside (USA) in2021. At the same time, it is noted that domestic regulations do not yet specify the methodology forcalculating buildings before progressive collapse, and the existing methods of experimental andnumerical analysis still need to be refined. Unfortunately, the list of such objects is increasing, andtoday, Ukraine has added to it numerous destroyed buildings as a result of ongoing hostilities on itsterritory. Therefore, for our country in the current conditions, the issue of ensuring the future stability of all buildings, and in particular, the housing stock against progressive collapse, is an urgent issue.On the basis of the analysis of the constructive solutions of the housing development in the city ofKharkiv, the type of buildings that, according to the authors of the article, has the greatest resource,is singled out, and brief recommendations are given for its increase in the future.
