Historic structures

The workshop will summarise state-of-the-art in the research of historic structures in order to improve and up-to-date mutual information about scientific achievements and capacity of research facilities in the pre-Accession to the EU countries and will support transition of this information to the EU countries as well as to the countries of Community’s external policy interests. It will help to select themes for medium term courses and joint or concerted research in this field and will gather data on relevant national and international funding possibilities. The workshop is aimed to influence cultural heritage research orientation and training of teachers necessary for a sound economic and social local or regional development. All this will be used for relevant networking and twinning arrangements and links among pre-Accession to the EU countries, as well as, between them and the EU countries in the area of cultural heritage research.

Description of the contents, the workplan, the steps, the approach or the methodology

Description of the current state and finding the reason of contingent damage of historical monuments must be based on proper diagnostic and evaluation methods. Non-destructive methods should be preferred in spite of problems arising from the interpretation of the measured data (inverse problems).

The question - how far is the structure from failure or what are the reasons for the observed damage - cannot be usually answered in the framework of standard design techniques. Safety factors applied for new constructions become often meaningless and another measures for results of the limit analysis must be considered.

Application of non-standard remedial and improvement methods requests a careful observation of structure reactions. Complex monitoring programs should be involved including remote control and data acquisition on site. Warning and critical states must be defined a priori which may be difficult in case of complicated structures.

All tasks mentioned in this Work Package should be supported by the theoretical modelling. Based mainly on the Finite Element Method, the interaction of structural parts, foundations and subsoil can be considered. Non-linear material models can substantially improve capabilities of the numerical modelling in spite of the more difficult and time-consuming computational effort.

Constitutive models for non-traditional materials can either be proposed or obtained by the modification of present well-established models.

Probability and stochastic mechanics approaches will be considered, too, because of the character of historic structures and their variable features.

The topics will further include study of structural types, historic development, etc.
