Selection of rational technical solutions for the repair of residential buildings

Abstract

The unsatisfactory technical condition of the majority of apartment buildings is explained by the fact that most of them were constructed during the period of rapid housing development (from the early 1960s to the late 1970s of the 20th century), the main objective of which was to erect buildings in the shortest possible time with minimal ­financial and material resources. This inevitably affected the quality of buildings, since inexpensive, low-quality, and short-lived materials were used in their construction. Moreover, the wide range of normative (design) service lives of the main structures, elements, and systems implies the need for their almost continuous repair or replacement.

At present, virtually all apartment buildings erected during the period of mass industrial housing construction are included in regional programmes for the capital repair of common property in apartment buildings. In this context, the selection of technical solutions for capital repairs is of critical importance, particularly those that involve the use of materials and products with design service lives corresponding to the residual service lives of non-­replaceable elements. The paper presents a methodology developed by the authors for determining the residual resource (residual service life) of structures, elements, and systems of residential buildings.
