Design of foundation of library building
Habanec, Kamil ; Novotný,, Petr (referee) ; Zich, Miloš (advisor)
The master’s thesis deals with the static solution foundation structure of the Moravian-Silesian Scientific Library in Ostrava. The goal is to process the design for the commissioned construction of the library building in detail, numerically and graphically, on the foundation supporting structure of the underground floors. Subsequently, their static solution, dimensioning and assessment for limit states. The solved elements are the foundation slab in the second underground floor, the bearing capacity of the piles and the foundation block of the core A. The static analysis was performed in a combination of the student versions of SCIA Engineer 22.0 and the Midas program. The work also includes drawing documentation for the above-mentioned elements. The calculation was carried out according to applicable standards and principles.

Static solution of concrete chimney
Kašparů, Jakub ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
The goal of this Master´s thesis is a review of a reinforced concrete chimney´s stack and a foundation design based on a combination of M+N load. Two bar models (by ČSN and EN) and one shall model were created to analyze internal forces. The fine element software SCIA ENGINEERING was used to create the models. The loads taken into consideration - for analysis include self weight, lining, temperature, wind, and Karman vortex. The stack was horizontally divided by several cuts which were investigated. The stack and foundation were designed by an algorithm created in the program MS EXCEL. The piles were designed in the program GEO 5. Drawings include - drawings of shapes and drawings of the reinforcement of specifics part of chimney.

Analysis of pile load test
Ponížil, Cyril ; Kotačková, Alena (referee) ; Fiala, Radek (advisor)
There is ussualy used the Masopust's method to assessment the piles in Czech Republic. This method is based on statistical processing of large data set of load piles tests. Due to the using of regression coefficients this method is relatively complicated and not very transparent. Instead, foreign standards ussualy use direct the values of limit stress on the base of piles and unit friction capacity. Procedure for determining the bearing capacity of the piles is thus considerably simplified. In this thesis the Masopust's method is compared with the methods used in Germany and Austria. This comparison provides insight to the safety level that include various approaches.

Design of prefabricated concrete hall
Cibičková, Viktória ; Chalivopulos, Paris (referee) ; Zich, Miloš (advisor)
The diploma thesis is focused on the design and assessment of a precast concrete hall. The first part of the work deals with the selection of a suitable layout solution from several proposed variants and a description of the technical solution of the object. After the load calculation, which corresponds to the nature of the building's use and climatic conditions, is followed by an assessment of selected elements of the structure, such as a typical purlin, girder, columns and foundation structures. The static assessment was determined through computational models and was accompanied by a manual simplified calculation check. The next part is devoted to creating a study of the structure's behavior. In the study, the design of several versions of the steel bracing system of the object was evaluated. The task was to choose the most suitable variant. Another goal of the study was the evaluation of the results of the global model from the nonlinear assessment through the software, as well as the evaluation of the results of the deformation caused by entering flexible supports into the computer software. In the last part, the proposed structure is demonstrated through assembly drawings, drawings of the shape and reinforcement of selected elements, drawings of assembly details, bearings and forgings. Visualizations of the object are part of the drawing documentation.

Pedestrian bridge across the river Nitra
Tomečka, Petr ; Kaláb,, Pavel (referee) ; Nečas, Radim (advisor)
The subject matter of this master thesis is to design pedestrian bridge across the river Nitra in a city Nitra. Out of three possible solutions arch bridge was considered to be the most optimal system for given situation and it was analysed in detail. The design and assessment of load-bearing structure was evaluated acording to valid standarts. The main goal was to comply with ultimate and serviceability limit state. Global calculation model was created in ANSYS Mechanical APDL 21 R2. Model of the slab of the deck in the cross direction was performer using SCIA Engineer 19.1. Load capacity of some cross sections was verified manually and some using computer software IDEA Statica 21.0. This thesis is extended with drawings of sequence of construction, detailed drawings of the bridge and visualizations.

Apartment Building
Švecová, Michaela ; Pilík, Václav (referee) ; Struhala, Karel (advisor)
The subject of this bachelor thesis is making the project documentation for construction of an apartment building in Vysoké Mýto. The apartment building is located on the western outskirts of Vysoké Mýto, in the residential area. It is a free-standing, three-storey, non-basement building with six housing units on the second and third floor. There are technical premises and four garages on the first floor. On the east side of the building, there is a parking lot and entrances to the individual garages. The vertical structural system of the building is made of Porotherm ceramic blocks. The building is insulated by a contact thermal insulation system with EPS insulation. Horizontal structures are made of reinforced concrete monolithic ceilings. The balcony boards are made of monolithic reinforced concrete with using ISO-supports. Vertical movement is possible through a staircase that is made of monolithic reinforced concrete or through the lift which is stored in a self-supporting shaft from monolithic reinforced concrete. The building is based on drilled piles in interaction with reinforced concrete foundation strips. The roof is flat, green in combination with pea gravel. The project was designed with a respect to current development in the area and with emphasis to the regulations. Parts of the work are schemes of technical equipment of buildings in the object and reviews of construction physics, in particular thermal technics, acoustics, insolation and lighting. The following programs were used: AutoCAD 2018, AutoCAD 2021, ArchiCAD, Teplo 2017, Světlo+, Building Designe, Microsoft Word, Microsoft Excel, Microsoft Publisher, Hluk+.

Dilatancy of soils as a factor influencing the bearing capacity and load - displacement response of deep foundations
Dvořák, Tomáš ; Koudela, Pavel (referee) ; Chalmovský, Juraj (advisor)
In theory of soil mechanic the dilatancy has a significant influence, which may fundamentally affect bearing capacity and behavior of geotechnical constructions. In the past it was difficult to include influence of dilatancy directly in to calculation, but now with development of numerical analysis and growth of computer performance it is much easier. In this work there are introduced fundamental dilatancy models and phenomen called constraint dilatancy, which causes stress changes in soil or at soil – construction interface. This stress changes may lead to higher bearing capacity. In this work, the effect of constraint dilatancy is focused on bored pile’s shaft. Next target of this work is including dilatancy to calculation. By empirical methods, by direct application with theory of cylindrical cavity expansion and last by numerical calculation with finite element method in software Plaxis with using the Hardening Soil model.
