Probabilistic Assessment Of Industrial Heritage
Structures: Framework And Case Study

M. Sykora & M. Holicky
Abstract
At present, considerable effort is aimed at the re-use of industrial heritage
structures in order to preserve their heritage value and avoid wasting energy.
Such structures do not often fulfil requirements of present codes of practice.
Decisions about construction interventions should be based on the complex
assessment of the structure considering actual material properties, environmental
influences and satisfactory past performance. Simplified conservative procedures
of structural design given in present codes may lead to expensive repairs and
losses of the heritage value. The probabilistic procedure is thus accepted to
enhance reliability assessment. Application is illustrated by a case study
concerning a former factory for boiler production. Two fundamental procedures
of probabilistic updating are described: (1) updating of the distribution of iron
strength using non-destructive and destructive tests, and (2) direct updating of
failure probability considering satisfactory past performance of the structure. It
appears that the probabilistic assessment may prevent expensive repairs.
