Assessment of the technical condition of load-bearing structures of buildings based on accident risk forecasting

Each building and structure are a complex technical system with predetermined technical parameters that must be monitored throughout the entire life cycle. The purpose of the study is to develop a methodology for quantitatively assessing the technical condition of load-bearing systems of buildings to improve their structural safety and operational suitability. The dependence of the actual wear of a building on the period of natural oscillations is determined based on the theory of predicting the risk of an accident, which allows determining an increase in the period of natural oscillations of load-bearing systems of buildings to assess the category of their technical condition. The limits of increase of the period of natural vibrations of bearing systems of buildings are defined. They allow quantitatively estimate the category of the technical condition (0-4% - normative technical condition, from 5-10% - serviceable, from 11-49% - limited serviceable, 50-95% and higher - emergency).
