Cable-supported bridge
Adler, Filip ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The subject of this master thesis is to design a pedestrian bridge supported by cables. There are three variants of studies created for this case and for most suitable one, all documentations were produced. The primary focus of this work is on static design solution with an output of several drawings. Static model for results from load cases included construction stages and was created in Midas Civil. Design and checks were performed by hand calculations, complemented by checks of several sections by IDEA StatiCa software. Analysis and calculations are compliant to up-to-date codes and respect the fundamentals of analysis due to limit states.

Arch structure footbridge
Machala, Zdeněk ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The subject of this master’s thesis is to design an arch structure of a footbridge. The bridge deck will be formed by a stress ribbon and could be divided into three parts. The middle part will be suspended (on the outer edges) on composite steel and concrete arches. Outer parts of the bridge deck will be formed by stress ribbons. The model of this construction is created in a computational program ANSYS and the solution is non-linear. The design is according to European standards.

Footbridge across the river Bečva
Totková, Lucie ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design of curved footbridge across the river Bečva. Curved footbridge consists of a supporting steel arch, which brings the steel struts to the steel arch under the concrete deck. The steel arch with crosspieces is coupled with concrete deck using the coupling pins. The deck is formed from reinforced concrete. Structural model is carried out in a computer program ANSYS. The structural design is handled in accordance with applicable European standards. The design considers pedestrians load and temperature effects.

Bridge across Bystrica creek
Nani, Pavel ; Glovina, Filip (referee) ; Zich, Miloš (advisor)
The subject of my diploma thesis is a detailed static calculation of the post-tensioned concrete road bridge across Bystrica creek near Banska Bystrica in Slovakia. The bridge is element of turning ramp a motorway R1. The spatial curvature continuous bridge has 9 fields. It was made a spatial curvature computational model of the bridge for a structural analysis. The model was comparison with a straight computational model of the bridge. It is made comparison effect of the construction bridge in stages on the size of the internal forces too. The load-bearing structure was checked according to CSN EN 1992-1-1, CSN EN 1992-2 and CSN 73 6214.

Footbridge across the deep valley
Kratochvílová, Martina ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the deep valley. There were designed three variants. The variant of structure, which combines stress ribbon with concrete arch, was chosen for the analysis. The optimal geometry was found using iteration methods with VBA Excel. The calculation model was made in software Ansys 19.0, considering phases of construction. The Ultimate limit state and the service limit state were evaluated as well as dynamic behavior of construction – modal analysis (eigenfrequencies and eigenshapes) and response to harmonic excitation. The design and assessment are according to the European standards.

Design of a prestressed slab
Juříček, Lukáš ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
Diploma thesis is focused on the design of prestressed concrete membrane from the lightweight concrete. The concrete membrane is in the interaction with the bearing steel structure, which one is supported. I did only one variant of the solution, which was optimized. The goal of the design was determined the initial state of a membrane and ensure to in the end of design working life was the membrane in the compression state and the cracks couldn’t appear. The structure is modelled in the main (longitudinal) direction as a spatial frame in program ANSYS 17.2. This tool enables to perform analysis of the construction stages. The rheology is calculated manually and supplied to the model as relative strain. The whole structure is checked for ultimate limit state and serviceability limit state according to valid Eurocodes. Transverse direction is modelled by shell elements in program RFEM 5.12. Construction stages and global behaviour of the structure were analysed. The checks have been calculated manually and control in program IDEA StatiCa. The attachments of the thesis are drawings, visualisation and schemes of construction stages.
