Abstract
Heritage buildings in the Czech Republic are made of different types of masonry.
Decisions concerning upgrades of these buildings should be preferably based on
a reliability assessment, taking into account actual material properties. Due to
inherent variability of historical masonry, information on its actual mechanical
properties has to be obtained from tests. Estimation of masonry strength from
measurements may then be one of the key issues in the assessment of historical
structures. In the submitted study, the standard technique provided in the
Eurocode EN 1996-1-1 is applied in the assessment of a masonry structure built
in the 19th century. Characteristic and design values of the masonry strength,
derived using principles of the Eurocode, are compared with corresponding
fractiles of a developed probabilistic model. It appears that the characteristic
value based on the probabilistic model is lower than that obtained by the
standard technique. To the contrary, the partial factor for masonry recommended
in EN 1996-1-1 seems to be rather conservative.
Keywords: masonry, characteristic strength, statistical methods.
