Evaluating Building Operational Safety under Variations of the Technical Condition of Foundations

Introduction. Modern buildings operate under changing climate and loading conditions, where foundation degradation leads to cracks, uneven precipitation and load-bearing capacity loss. Regular monitoring and inspections enable timely risk detection, accident prevention and repair cost reduction. The aim of the study is to develop methods for assessing operational safety across various foundation conditions, including calculating precipitation and performance limits.

Materials and Methods. The study included visual inspection, structural scheme identification, instrumental diagnostics, building inspection with preparation of the architectural drawings, defect detection and documentation, installation of pits with preparation of measuring drawings of еру foundations for open pits and identification of the strength characteristics of the foundation material, opening structures and testing building materials to identify their strength characteristics with subsequent verification calculations of the load-bearing elements.

Research Results. Based on the results of the verification calculations and identified structural defects, the condition of the building elements and the building as a whole has been established. Recommendations have been developed for ensuring the normal operation of a building as well as for strengthening or repairing structures.

Discussion and Conclusion. Comprehensive technical inspection of the building using advanced non-destructive testing methods and verification calculations revealed the current technical condition of the foundation elements and foundations. Based on the results of the technical inspection, taking into account the results of the verification calculations, it can be concluded that for further normal operation of a building in some areas, it is necessary to take measures in order to strengthen the foundations or strengthen foundations soils. The scientific significance lies in the developed and testing of the methodology for comprehensive assessment of the load-bearing capacity of foundations taking into account realworld operating conditions, which makes it possible to increase the accuracy of forecasting the durability of buildings on weak soils. The practical value of the results lies in the formation of specific recommendations for strengthening foundations. The findings can be used in inspecting similar civil and industrial facilities.
