Cast-in-place tank
Laurinyeczová, Erika ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The thesis deals with the analysis of a reinforced concrete digestate tank. The tank is built as a semi-underground construction. The roof is designed as a reinforced concrete dome, which is prestressed in a circular beam with prestressing cables - monostrands. The calculation of internal forces were performed by the software SCIA Engineer. The structure was assessed for the ultimate limit state and the ultimate serviceability state, in terms of watertightness for the width of cracks.

Prestressed bridge on the expressway
Juřenčáková, Jana ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The purpose of the diploma thesis is to design a expressway bridge over the river Vsetínská Bečva. The bridge is located between Valašské Meziříčí and Vsetín. Separate superstructures are designed for each directions of the expressway. The right superstructure, which is wider, is considered for detailed design. Two variants were proposed, A double T beam superstructure and a box girder superstructure. The three span box girder superstructure was chosen for the design. Spans are 48+65+48 m long. Two options of construction process of the superstructure were proposed. This bridge is designed according to the limit states, the influence of construction process is considered. Structural models of construction were made as a finite element model and a plate model. Structural analysis, drawings and visualization were developed.

Reinforced concrete construction of cooling tower
Zralý, Tomáš ; Buřič, Pavel (referee) ; Šulák, Pavel (advisor)
There was solved reinforced concrete cooling tower in the diploma thesis. This is a rotationally symmetrical construction. The cooling tower is concrete shell on columns. The cooling tower was solved using the finite element method, computer program Midas FEA. The work includes: calculation using the program Midas FEA, comparison of load between eurocode and foreign literature, the design of shell and columns, drawings form

Návrh konstrukce suchého doku pod svislým zatížením
Zetková, Simona ; Polák, Barnabás (referee) ; Uhrin, Michal (advisor)
The aim of this thesis is to undertake simplified design and assessment of cofferdam under vertical surcharge in the form of virtual project. Cofferdam constructed on the sea shore must be able to withstand all loads to enable construction of cut and cover tunnel. As a part of the design it is required to assess ground conditions and it is necessary to review feasibility of the structure on the sea. The construction will be described in construction phases and graphically demonstrated in construction sequence drawing. Because the structure is designed for life time of five years, temperature load on struts is studied in the thesis and further considered in structural analysis. Furthermore, it is required to compare analytical models from GEO5 and PLAXIS. Horizontal frame is analysed separately in Scia Engineer. Structural members – cofferdam wall, waler beam and strut are checked in this thesis. For the design of the cofferdam wall second order theory is considered. All mentioned requirements were accomplished with help of corresponding Eurocodes, books and technical advice. Results of this work are feasible and it was possible to design all members to enable construction of the cut and cover tunnel. The phasing was designed such that deformation of the cofferdam is minimalized and use of machinery is limited to machines on temporary platforms. Comparison of two different analytical models showed that different soil modelling has great effect on internal forces, even though the shape of the bending curve is very similar, values obtained from PLAXIS software are much higher. Assessment of the structural members is done according to Eurocode 3, and horizontal frame is checked also against disproportionate collapse.

Cast-in-place tank of sewage plant
Sivčák, Jozef ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The master’s thesis designs and checks the reinforced concrete tanks of sewage plant. Part of this thesis are also drawings. Tanks are designed as a watertight underground structure with aspect on standards and watertight function. Foundation slab and concrete walls were designed according to ultimate and serviceability limit states. The thesis includes design of reinforcement according to non-force effects in early stage. The structure is checked also to loss of equilibrium of a structure due to uplift by vertical actions from water pressure.
