Abstract: The objective of the study is to review the theoretical and practical methods for determining the reliability of buildings that have been in operation for more than 50-70 years. The necessity to survey the technical state of the operating buildings to monitor the required parameters of their reliability and safety has recently become one of the most important activity areas for research, design and construction organizations because cases of collapse of buildings over the world all have become frequent.
The work is based on analysis of existing approaches, experimental and theoretical studies in the area of reliability of buildings and structures. The results of surveying the partially ruinous 4-storey residential building are considered and analyzed. The technical condition of certain structures is defined as a result of a general analysis of defects and damages determined by the results of the preliminary inspection.
The analysis of the stress-strain state of the collapsed building was performed on the basis of verification calculations by using modern program complex “Lira”. The verification calculations have been performed for two conditions of soil base of foundations: the natural condition of soil base and soaked condition of soil base.
The procedure of revealing the causes of building collapse and recommendations of its possible restoration is discussed also.
