Assessment of existing structures should be based on the actual as-built conditions concerning geometry, material properties, loading and environmental conditions. A crucial step of the assessment is the updating of prior information by newly obtained measurements which can be conducted by a Bayesian approach. Updating of probabilistic distributions of basic variables or direct updating of failure probability can be used effectively. The application of theoretical principles is illustrated by the case study of a historic factory built in 1900s.

Key words: Bayesian approach, existing structures, industrial heritage, probabilistic updating, reliability assessment
