Steel Beam Structure Optimization
Lamoš, Radek ; Eliáš, Jan (referee) ; Frantík, Petr (advisor)
The main subject of this work is to find ideal solution of the steel frame structure and offer the best solution to investors. The aim is to get know how steel structures works, write down internal forces when parametres are changing. Parameters can be profiles, loads or many others. The output should be perfectly optimized construction. The content combines theory of structural mechanics and designing steel structures. This project could be very useful in practice designing of steel frame structures with the possibility of expansion by other parameters.

Cable supported bridge
Kolář, David ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The topic of this bachelor thesis is design of a footbridge across a river. The final version, which has been chosen from three designs differentiating in their static behaviour of the structure, is a cable-stayed footbridge. The chosen option is designed as a parabolic monolithic prestressed deck suspended by cables anchored to two cone shaped pylons. The structure is situated perpendicularly to the riverbed and its total length is 57,465 m. Softwares, such as SCIA Egineer 20.0 and MS Excel, were used for the calculations of internal forces and modelling calculation models and its verification by hand. The design of the prestressing force, assessment of utility limit state and serviceability limit state were done by hand according to valid standards and regulations. Partially simplified bearing capacity assessment of the pylons was solved by IDEA StatiCa 9 software and some of the results were verified by hand as well. The thesis disregards stages of construction and prestress losses are estimated.

Prestressed bridge in Velké Pavlovice
Stloukal, Radim ; Růžička, Stanislav (referee) ; Koláček, Jan (advisor)
The subject of this thesis is to design a bridge construction over the river Trkmanka in the municipality Velké Pavlovice. The superstructure is designed as a prestressed one field slab bridge with the length of 16,85m. As a part of this thesis there is enclosed structural analysis calculated accordingly to ČSN EN 1992-1-1. The load effects were calculated by Scia Engineer and compared with manual calculation. The rest of the calculations are done manually and ocassionally compared to engineering software. The construction has been analysed for the ultimate limit state, serviceability limit state and the stress anchors have been designed.

Bridge on a highway
Knotek, Jan ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
Subject of this bachelor’s thesis is design of new slab bridge construction over the II/464 road between the villages Příbor and Bílovec. The bridge converts highway D47. Thesis includes three studies. Pre-stressed rectangular cross-section slab with elliptical exterior trim, pre-stressed plate- grinder construction and construction of prefabricated beams and monolithic slab. For next assessment was chosen option no.1. Load effects calculation is solved in SCIA engineer 16.1. Design and assessment of the structure are made according to valid standards and regulations.

Analysis of behaviour of reinforced concrete slab
Kubínek, Michal ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
Bachelor thesis describes the analysis of behavior of existing reinforced concrete slab, locally supprorted, ceiling in hospital including 2nd limit state. Calculation od internal forces was made by computer program SCIA Engineer. Several models were made, model with best behavior due to real construction was used for dimensioning. Each model was compared with manual calculation by equivalent frame analysis. After finding inconvenient deflection, especially due to connected construction, new design was made. Thickness of slab was increased and new design of reinforcement was made. New construction was verified for both limit states.

Static analysis of reinforced concrete floor structure of historical building
Nani, Pavel ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
The chief objective of my bachelor’s thesis is a design of the reinforced concrete floor structure of a historical building over 1st floor. The historical building was built in 1874. There are three floors in this building and there isn’t any underground floor. The reinforced concrete floor structure consists of the following forms of structure – a ribbed ceiling, a floor slab, a beam, a shell of vault and a staircase. The ribbed ceiling is made from a lost formwork of the VELOX firm. The set reinforced concrete floor structures are according to ČSN EN 1992-1-1.

One span frame bridge
Buk, Petr ; Zich, Miloš (referee) ; Nečas, Radim (advisor)
The subject of this bachelor thesis is design of road bridge across the river. From the developed variants, one was selected. Selected variant deals with one span frame bridge. Construction is made of panel with run-ups from prestressed reinforced concrete. Bridge is designed perpendicular, with span range of 25,0 m. For the calculation of internal forces two computing models (rod and panel model) were made in SCIA Engineer 2018 program. Thesis deals with comparisons of internal forces in rod and panel model and comparison of short-term losses with SCIA Engineer 2018 program. Design and assesment of ultimate limit state and ultimate serviceability state was conducted in accordance with applicable standarts and regulations.

The roofing of amphitheatre in Vizovice
Kuchtová, Ludmila ; Štrba, Michal (referee) ; Šmak, Milan (advisor)
The scope of this bachelor’s thesis is to design roofing over a natural amphitheater stage in Vizovice. The structure is designed as a variable structure in verison of both steel and timber. Each solution has a different structural composition. The layout is triangular with width of 18 meters and length of 15 meters. The height of the roofing is considered to be 9 meters.

Design of excavation for reconstruction of shopping centre
Červenka, Jan ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
The thesis is divided into three parts. In the first one it deals with the design and the assessment of the once-anchored soldier pile wall, which provides an excavation for the reconstruction of the shopping centre Prior in Zlín. The retaining structure is designed according to the limit state method, using the GEO5 software and the Excel spreadsheet editor. In the second part, the thesis deals with the price comparison of the classic version of the soldier pile wall with soldier pile, IPN profiles, with over one-pole anchorage with the help of the buckle, with the variant with larger spread, where the soldier pile from the pair of UPN profiles are adapted for anchoring. The third part solves the problem of the distribution of a lateral ground pressures along the length of the soldier pile wall. For comparison with the empirical methods of design of lagging, the results of normal pressure from the mathematical model, solved by the numerical analysis, the finite element method, were used in the Plaxis 3D program. Hardening soil model was used as the material model.
