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.

Bridge in Lipová Lázně village
Christ, Roman ; Bezručová, Kristína (referee) ; Panáček, Josef (advisor)
The subject of this bachelor thesis is the design of a perpendicular bridge structure across the Staříč River in the village of Lipová Lazne. The bridge translates communication II. class number 369, design category S7,5. Three design variants of the plate bridge are elaborated on a single field. The chosen variant is solved by means of an additional prestressed plate of a rectangular cross-section of height from 1000 mm to 920 mm in width and length of the supporting structure 20850 mm. The static model is solved as a simply supported plate with a bridging length of 18420 mm. The design was executed according to the standard ČSN-EN 1992-2. Calculation of load effects was performed using Scia Engineering 2019 software. Design and design assessments have been carried out according to the applicable regulations and norms.

One span frame bridge
Černý, Pavel ; Juříček, Lukáš (referee) ; Nečas, Radim (advisor)
The aim of this bachelor thesis is the design and analysis of bridge across the river. Three variants were designed. The structure was designed as a one-span frame bridge with a parabolic haunch with of span range of 24,0~m. The calculation of load efects eas made in software Scia Engineer and for evaluation was used MS Excel. Both design and relevant drawing documentation of the bridge deck and abutment.

One span tee beam bridge
Lachová, Alžběta ; Zich, Miloš (referee) ; Koláček, Jan (advisor)
The goal of this bachelor Thesis is to design a single span road bridge. The bridge will transfer a road of a S7,5 category over local river. Three possible variations were designed, from which option A will be used for further design and calculations. This bridge is a monolithic single-girder post-prestressed construction with a span of 24 m. The structure has been calculated for the ultimate limit state and the service limit state. The calculations of the load effects were done manually as well as in software Scia Engineer 19.1.

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.
