ABSTRACT
The article presents the results of a comparative analysis of the extent of damage to 86 prefabricated residential buildings constructed in the large-panel technology. The study was conducted for the buildings located in the mining area of Legnica-Głogów Copper District (the Wk-70 and WWP groups) as well as for those located in Kraków, out of the reach of mining impacts (the WUF-T group). To describe the condition of these buildings, damage intensity rate wu was used. Its purpose was to specify the extent of damage to the building individual construction and finishing elements. The wu rate was defined in a 6-point scale, which included a detailed description of the extent of damage corresponding to the consecutive degrees of intensity. The study involved a comparison of the mean values of the intensity rate of the damage to the individual elements of buildings located in the mining area and out of the reach of mining impacts, taking into account a categorization with respect to the technology applied. Despite a generally moderate extent of damage, in 3 cases, statistically significant differences were identified between the rates of damage to the elements of the buildings located in the mining area (Wk-70 and WWP) in comparison with the group of building structures situated outside the mining area (WUF-T). In addition, in 7 cases, higher values of the intensity rates of damage to the elements of the buildings subject to the mining impacts were obtained.
