Design of foundation pit in metro construction in the section Dejvická - Motol
Krško, Matúš ; Kliš, Lumír (referee) ; Miča, Lumír (advisor)
Diploma thesis deals with design and assessment of bracing the excavation during the construction of subway in the route Dejvická – Motol. The introduction presents possible methods of bracing. The next part is design and assessment of the chosen option, which ensure this construction. It consists of considering of engineering-geological conditions, static design, technological process of building and construction plans.

Verify stability of ground anchor system
Krško, Matúš ; Doněk,, Michal (referee) ; Miča, Lumír (advisor)
Bachelor´s thesis is focused on stability of anchored system. Theoretical part deals with various types of anchored walls, their construction technology and failure states that can occur. Methods for assessment of internal stability are presented in the next step. They are applied to a model anchored wall in a calculation part. Obtained results are evaluated at the end the thesis.

Design of Gravity Wall in Terms of Flysch Geology
Horňáková, Lenka ; Fiala, Radek (referee) ; Brdečková, Helena (advisor)
The bachelor´s thesis is divided to two main parts, from which first is focused on the theory of reinforced concrete retaining walls. The second, practical part deals with design and assessment of the cantilever breast wall supporting the sloping slope in place of annex of congress hall situated above the northern wall of Tatra´s hotel in Velke Karlovice. The labor contains processing of geomorphology and geology surrounding area, load, sample calculation cantilever breast wall and its assessment.

Footbridge across the Labe
Krč, Rostislav ; Romportl, Tomáš (referee) ; Stráský, Jiří (advisor)
The thesis focuses on design of prestressed concrete footbridge which passes pedestrian and bicycle path over the Elbe river near city of Celakovice in the Czech Republic. Three different bridge options were analyzed and for further development a cable-stayed footbridge was chosen. Its bridge deck is formed of a box girder supported by cables in its vertical axis and all cable stays are anchored into two concrete A-shaped pylons. This structure was analyzed in SCIA Engineer and assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Both the global structural behavior and the local structural integrity of box cross-section were assessed as well as construction stages and cross-sections of pylons and cable stays. Assessments were performed in IDEA StatiCa combined with hand calculations. Eventually a dynamic response of structure was analyzed. Natural modes and frequencies were found and forced oscillation response was evaluated. The thesis includes technical drawings, construction process and visualization.

Concrete structures with FRP reinforcement
Valent, Matej ; Januš, Ondřej (referee) ; Girgle, František (advisor)
The bachelor thesis deals with the usage of FRP reinforcement in concrete structure designs. The designed structure is a sedimentation reservoir that consists of two prefabricated segments. The construction is classified into the XC4 exposure category. The theoretical part of the thesis provides an overview and explains particular types of FRP reinforcement, their properties, and mechanical durability. We describe GFRP reinforcement and its design for bending and shear, consecutively providing different approaches in a plan for a short-term or long-term carrying capacity. The experimental part of the thesis contains two alternatives. The first application involves B500B reinforcement in both prefabricated segments, while the second part, it is using Schöck ComBAR® reinforcement instead. Moreover, both possibilities and their design take into consideration the ultimate limit state. Subsequently, the obtained results are compared. The experimental part of the thesis includes calculations as well as drawings documentation.

Prestressed road bridge in Staré Město
Krč, Rostislav ; Trenz, Jan (referee) ; Koláček, Jan (advisor)
The thesis focuses on design of superstructure of concrete bridge, which passes a roadway across the river Krupa in the town of Stare Mesto. It is a simple span structure with length of 19 meters. For further elaboration, post-tensioned concrete slab with trapezoidal-shaped cross section was chosen. Assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Furthermore, a design of post-tension according to former Czech technical standards (CSN) was studied. The thesis includes technical drawings and visualization.
