Static analysis of a concrete outlet channel
Skalník, Stanislav ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The thesis deals with the static analysis associated with the outlet channel of the lock chamber. The basis for the work was the design of reinforcement using full-threaded prestressing bars and the drawing documentation of the existing condition. The aim of the work was to present the issues associated with the anchoring of the prestressing bars by cohesion in the existing concrete structure, in particular testing on test blocks in the laboratory to verify a suitable solution. Following the data obtained, to perform an analysis and comparison on models solved by nonlinear computation in ATENA Science software. Subsequently, the analysis of the model of the existing condition of the outlet channel section is also carried out by nonlinear calculation with the evaluation of its behaviour to extreme loads. This model is then supplemented with reinforcement using prestressing bars with application of the knowledge associated with the pullout test models. The model of the pre-stressed outlet channel section is thus a simulation of the design on the lock itself.

Development of progressive polymer anchor material
Žlebek, Tomáš ; Jakubík, Aleš (referee) ; Drochytka, Rostislav (advisor)
The diploma thesis deals with development of a new progressive anchor material on the polymer base. Nowadays, it is effort to utilize secondary raw materials in building industry as much as possible both from an environmental aspects in order to save primary energy sources and the reduction of waste and also due to economic reasons. Therefore, there is an effort to utilize high amount of suitable and appropriately treated secondary raw materials into the anchor materials. The main aim of this work is to develop high quality anchor material characterized by excellent ratio between speed and strength growth, high chemical resistance, thermal resistance and particularly minimal shrinkage. This new material is designed especially for anchoring building structures heavy machines steel barriers and other elements.
