【 摘 要 】

The article offers an approach to building collapse risk evaluation with damage localization. As a rule, the risk includes the probability and value of loss. The probability of failure for separate construction is determined by known methods, but for risk-management decisions these methods are too complicated. The solutions of the problem, using the specified theoretical base, are considered: for structural damages of the constructions the simple rules of criticality degree determination are used; they are based on fuzzy logic, which ensures the efficiency of structural state assessment. The represented risk assessment method is also based on technological and social loss cost evaluation for various areas under failed constructions and different accident scenarios. The risk oriented approach can be applied in few related areas of construction, from design to insurance.
