Safety or reliability of a structure is formulated in terms of an uncertainty factor combined with a generalized allowable risk. The uncertainty factor allows the consideration of incomplete information and imperfect knowledge in the specification of a permissible risk level. This allows the use of judgment and the explicit use of probabilistic information in the design of safe structures.
