“…In case that the requirements of currently valid standards for structural design had to be fulfilled, it would be necessary to make strengthening or replacement of the weakened parts and joints of the structural load bearing system. However, the valuable original structural system of the monumental main arch of the stadium need to be preserved which illustrates the architectural feeling and masterwork of the last century in the Czech Republic [7,8,9,10].…”

Decision on repairs or strengthening of existing structures with special focus on heritage structures or structures with areas where people may congregate has to be based on detail technical survey according to ISO 13822 and ISO 2394. The extent of structural intervention has to be always well planned taking into account economic, societal and environmental aspects. It is necessary to consider whether instead of significant structural intervention which could lead to unneeded economical loss of existing structures or also to the loss of heritage value of historic monuments, it is not better to make optimisation of structural intervention and accept the procedure for effective risk management.

<p>The mechanical properties of historic metal materials exhibit a considerable scatter dependent on periods of construction and the region of a producer. Assessments of historic metal bridges then need to be based on measurements and tests. The use of non- or minor-destructive tests (NDTs) is often preferred over to destructive tests (DTs) to reduce the cost of structural survey. This contribution explores the measurement errors associated with common NDT hardness techniques and quantifies uncertainties in design (assessment) values of resistance. When deriving the partial factor, the uncertainty in geometry and model uncertainty is considered along with the variability of a material property and measurement error. Numerical studies reveal the effects of measurement error and model uncertainty (bending, buckling) on assessment values of resistance. A unity mean and coefficient of variation of 12% might be adopted for the measurement uncertainty of the hardness methods under study as a first approximation. On average, the true assessment resistance is by ~15% larger than that based on a NDT survey. Model uncertainty affects the partial factor for resistance of historic metal bridges.</p>
