Abstract (en)
Timber-concrete composite structures represent a composite system that is
formed by coupling of timber and concrete elements using different types of
connectors. They are applied in the rehabilitation and construction of new
facilities. In order to enable their wider application, it is necessary to ensure
the general availability of relevant technical regulations in relation to their
design and construction.
The main goal of the doctoral dissertation is to contribute to the
improvement of the design process of timber-concrete composite structures
and their maintenance during the service life. Thus, certain multi-parametric
probabilistic analyzes and optimizations should be carried out which would
result in certain recommendations that would have practical application in
the certain conditions of design, construction and maintenance of these
composite systems.
In order to determine the most important design parameters, a stochastic
sensitivity analysis of the maximum equivalent stress and maximum
deflection of the timber-concrete composite beam was performed. A multiobjective
optimization was also conducted in order to choose an optimal
solution for the dimensions of the observed composite beam. A new
probabilistic deterioration model has been developed that describes the true
nature of the behavior of the timber-concrete composite system due to the
long-term load.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
