Suspension footbridge across the river
Chumová, Petra ; Bartoň, Jaroslav (referee) ; Nečas, Radim (advisor)
The subject of the thesis is to design a suspension footbridge over a river basin. Three different studies were created for the assigned problem. The suspension footbridge was chosen for the thorough elaboration. The most important part of the thesis is the static solution of the supporting structure. The structure model for calculation of impacts of selected strains including the impact of the footbridge construction was created in computational software Ansys. Assessment and dimensioning was carried out using manual calculation according the principles of limit states and applicable standards.

Pedestrian bridge across the river Morava
Nováček, Jan ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
Subject of the work is design of pedestrian bridge across the river Morava. There are compared 3 variants of structures. Thesis is focused on stress ribbon supported by arch. The geometry of initial stage has been searched to form self-anchored structural system. The structure is verified in according to the European Standards.

Steel Footbridge
Honeš, Filip ; Šmak, Milan (referee) ; Bajer, Miroslav (advisor)
The main subject of master´s thesis is design of the construction of pedestrian steel bridge via the river Bečva in Přerov. It was made a three different types of the steel construction. The resulting draft is worked up in details. Span of the pedestrian bridge is 104 metres. The carrying construction is made from a two mutually-opening arches. Between the arches are hanged a semi through type decks.

Static and dynamic analysis of Prestressed bridge structure
Hokeš, Filip ; Nečas, Radim (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to perform static and dynamic analysis of prestressed concrete bridge structures in computational system ANSYS. For the analysis was chosen footbridge over the river Svratka in Brno. In relation to this topic are solved various types of modeling prestress at a finite element level. Before analyzing the footbridge is analyzed in detail the static system and the corresponding final geometry of the structure. Knowledge of the functioning of the static system is used to build the computational model of the structure, on which is subsequently performed static and dynamic analysis.

Wind loading of lightweight bridge-like structure
Hrubý, Pavel ; Kala, Jiří (referee) ; Nevařil, Aleš (advisor)
The present thesis is concerned with air flow over lightweight footbridge. Special attention is paid to flow-induced instabilities. The thesis opens with a theoretical elaboration on the phenomena related to the research matter. The next part investigates air flow over footbridge in a specific situation using numerical simulation in the Ansys CFX software. Finally, results are discussed in the light of chosen theoretical framework and relevant conclusions are presented.

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 in Nova Karolina in Ostrava
Havelka, Jiří ; Nečesal, Petr (referee) ; Marván, David (advisor)
The topic of the master’s thesis is a design of steel structure of footbridge. Footbridge goes across the roadways and railway. It is a design of a new structure in Nová Karolina in Ostrava. Span of footbridge is 200m. The footbridge’s superstructure is two steel arches angled toward each other and fixed to the foundation blocks. The supporting beam of the bridge deck is connected to the arch by tie-rods. The deck beam is a welded box section. The tie-rods are arranged to the V-shaped system. Deck of footpath is semi through type and orthotropic. The arches are connected at the top by lateral bracing. Lateral bracing is Saint Andrew's Cross type system.

Pedestrian Footbridge
Báča, Pavel ; Puchner,, Josef (referee) ; Brosch, Petr (advisor)
The subject of this student work is the design of a load-bearing steel structure of a footbridge for pedestrians. The footbridge connects two buildings in the locality of Brno - Bohunice. It includes the bridging of a road, car park and entrances of the both buildings. The construction of the footbridge is solved in three variants with the best variant selected.

Design of the footbridge over the railway
Mertová, Eliška ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
The aim of this bachelor´s thesis is a design of a new footbridge over the railway instead of an existing reinforced concrete pedestrian bridge in a compound of the cement factory in Mokrá at Brno. The footbridge is used to the transfer pedestrians over the mentioned train. The work is composed of the design of the pedestrian bridge as a continuous frame structure, including making a model of the bridge for an analysis of internal forces, design and checking the structure for the ultimate and serviceability limit state. A calculation of load effects is processed by the computer software Scia Engineer 2013. The construction stage analysis wasn´t applied in the structural calculations.
