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.
