Concrete flat slab supported by columns
Turek, Jan ; Požár, Michal (referee) ; Perla, Jan (advisor)
This bachelor thesis deals with design of concrete flat slab of hospital building. The slab above the ground floor was designed. Internal forces were analysed with RFEM software based on finite entity method. Results were proved by the Direct Design Method and Equivalent Frame Method. The structural assessment was performed according to ultimate and serviceability limit states.

Design of cable-stayed pedestrian bridge
Uher, Lukáš ; Kulhavý,, Tomáš (referee) ; Nečas, Radim (advisor)
This diploma thesis aims to design a structure of pedestrian bridge over the Svratka river. To make a preliminary study of possible bridging, three different outlines were drafted. The cable-stayed variant was selected for further analysis. Two towers, inclined in both their longitudinal and transverse direction, support a cast-in-place post-tensioned concrete deck through stay cables anchored in the tower and the deck. After determining the desired initial state, a finite element analysis was carried out using the Ansys software. The capacity of all main load-bearing elements was checked so it meets the ULS and SLS design criteria in accordance with EN 1992 codes.

Design of strengthening of the concrete structure from 1928
Bažantová, Lenka ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The bachelor’s thesis is focused on assessment of the existing construction four-storey building. The supporting system consists of cast-in-place concrete frame. The aim of this work is to assess the support structure for the expected loading of the resulting change in use of buildings for residential or commercial purposes. The subjects of assesment are columns, beams, girders and floor slab. In another part of work is suggested by reinforcement of non-conforming elements. The work includes the development of stroctural analysis and reinforcement drawings of reconstructed elements.

Design of Load Bearing Concrete Structure
Klodner, Jan ; Vácha, Jaroslav (referee) ; Štěpánek, Petr (advisor)
This thesis is focusing on general issues of floor concrete slabs, technology, implementation, subsoil models, calculation of internal forces and design approaches. Based on these data the thesis monitors the behaviour of floor slabs according to the various parameters. It also includes three versions of design of the real floor slab, made of steel fibre reinforced concrete, reinforced concrete and prestressed concrete. Economic comparison is also included. In addition it developes a design of the chalice base and reinforced concrete column of the supporting hall system, instead of the original usual base with steel column.

Multi-storey building for administrative purposes
Lehocký, Peter ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
This bachelors thesis deals with design of administrative building adjacent to a metalworking shed. The administrative building is statically independent on metalwork shed. Building is located in Brno. Floor plan of building is in shape of letter L. Axis distance of columns is 9m longitudinal and 7,5m transverse. Total length of building is 27m longitudinal and 15m transverse ( distance is measured between axis of columns). In narrow part of transverse is width of the building 7,5m. Ceiling is made of composite steel-concrete structure. Height of the building is 18,7m.

Model of a prefabricated footbridge for teaching
Gaidos, Daniel ; Koláček, Jan (referee) ; Strnad, Jiří (advisor)
The subject of this thesis was to design a test model of a foot bridge built out of sets of blocks, coupled by prestressing monostrands into one beam. Created model will serve as a test model during the training of machinists on tensioning equipment. Static model for results from load cases was created in Scia Engineering 20.0. Assessment and dimensioning were solved in the MS Excel program. The structure was assessed for the limit state of load-bearing capacity and serviceability. Analysis and calculations are compliant to up-to-date codes and respect the fundamentals of analysis due to limit states.

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.
