Title of the articleThe problem of erosion of facades of historic buildings from wind impact of rain
Abstract.The relevance of the study is due to the fact that surface erosion of building materials is a common phenomenon observed on the facades of historic buildings. Climatic changes may lead to an increase in the frequency and intensity of extreme precipitation events, which may increase erosion effects on building facades due to the impact of oblique rainfall. The aim of the study is to compare experimental methods for assessing the degree of surface erosion of historic building materials under the influence of oblique rainfall. The objectives of the study are to review modern methods of measuring the effect of rain with wind on surface erosion and strength reduction of bricks and limestone; to analyze the most known methods of assessing the degree of erosion of the surface of building materials; to propose recommendations for the protection and restoration of damaged facades of cultural heritage objects due to the impact of oblique rain. Results. Based on the analysis of modern research, recommendations for the protection and restoration of damaged facades of cultural heritage objects due to the effects of oblique rain are proposed. Kazan State University of Architecture and Engineering has created a testing complex «Sealed chamber», which allows conducting further experimental research to assess the impact of oblique rain on surface erosion and strength reduction of building materials taking into account the advanced foreign experience. Conclusions. The significance of the results obtained for architects and designers is that the use of the methods for assessing the degree of damage to the facades of architectural monuments due to the effects of oblique rainfall allow monitoring and developing measures to protect cultural heritage sites.
Keywords.wind-driven rain, erosion of masonry, protection of facades of monuments
