Cable-supported pedestrian bridge
Knotek, Jan ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
The subject of this diploma thesis is design a cable-supported pedestrian bridge. Three different variants of the solution were created for the design. For detailed processing, variant no.2 was chosen - a suspended bridge with a pylon in the middle of the span. The main task is the static design of the supporting structure. The model for the lengthways is created in ANSYS. The SCIA engineer was used to solve crosswise. The assessment and dimensioning was done according to the limit state principles and valid standards.

Pedestrian bridge at Veveří Castle
Slovják, Petr ; Juchelková,, Pavlína (referee) ; Koláček, Jan (advisor)
The subject of this thesis is alternative design of the pedestrian bridge over Brno reservoir near Veveří castle. Three preliminary studies are created. The chosen variant consists of a stress ribbon supported by a steel arches. Time dependent analysis of load cases effects during construction stages is calculated by ANSYS. The bridge is verified according to the European Standards.

Steel footbridge for pedestrians and cyclists
Sýkora, Jiří ; Pešek, Ondřej (referee) ; Štrba, Michal (advisor)
The aim of the work is to design a steel footbridge for pedestrians and cyclists in Brno. This is a valley bridge where there is no road for vehicles. All motor vehicles are not allowed to entering the footbridge. The theoretical span of the bridge is 50 m, the height of the structure is 7 m. The bridge deck is elevated by 0,5 m in the arch. Two variants have been proposed. The more suitable one was selected by comparison according to several criteria, for which a detailed structural analysis and drawings were prepared.

Pedestrian bridge across the river Nitra
Tomečka, Petr ; Kaláb,, Pavel (referee) ; Nečas, Radim (advisor)
The subject matter of this master thesis is to design pedestrian bridge across the river Nitra in a city Nitra. Out of three possible solutions arch bridge was considered to be the most optimal system for given situation and it was analysed in detail. The design and assessment of load-bearing structure was evaluated acording to valid standarts. The main goal was to comply with ultimate and serviceability limit state. Global calculation model was created in ANSYS Mechanical APDL 21 R2. Model of the slab of the deck in the cross direction was performer using SCIA Engineer 19.1. Load capacity of some cross sections was verified manually and some using computer software IDEA Statica 21.0. This thesis is extended with drawings of sequence of construction, detailed drawings of the bridge and visualizations.

Cable-supported bridge
Kovářová, Marika ; Bezručová, Kristína (referee) ; Nečas, Radim (advisor)
The theme of the thesis is to design a pedestrian bridge over a river. Out of two possible designs, the cable-stayed construction was chosen. The deck of the bridge is designed as a monolithic construction supported by cables from two inclined pylons. Two models were developed for the calculation of internal forces: a strut model for the longitudinal direction and a plate model for the perpendicular direction. These calculations were checked up by Finite Element Method (FEM) in SCIA Engineer 2017 software. Considerable part of the thesis was dedicated to the creation of so-called initial state. The design of the prestressing force and the evaluation of ultimate limit state and serviceability limit state was made in accordance with the codes currently in force. Small part of the theses is dedicated to the verification of the load bearing capacity of the pylon on the combination of normal force and bending moment with a subsequent verification in the software IDEA StatiCa9. The pedestrian bridge of 64,150 m length is considered as a perpendicular.

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.

Stress ribbon bridge across the deep valley
Tomisová, Gabriela ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
The topic of this thesis is a design of stress ribbon bridge across the deep valley. The construction of the footbridge contains stress ribbon bridge with external cables and final prestressing tendons. The bridge deck is in a parabolic arc and the suspension cables are in two bend down parabolic arcs. The construction is reproduced for evaluation of longitudinal direction in the Ansys 14.0 programme and for transversal direction in the Scia Engineer 15.1 programme. The model was solved in several phases, nonlinerally. The pier was reproduced in the Scia Engineer 15.1 programme for local effect of action. The construction was evaluated for dynamic action. The construction is assessed according to the actual EN standards.

Pedestrian bridge across the highway D1 in Bohumín
Muroň, Vlastimil ; Puda, Vladimír (referee) ; Nečas, Radim (advisor)
The aim of final thesis is design and assessment of footbridge over highway D1 in Bohumín. The design is processed in two options. From these two options there is cable-stayed construction solved in greater detail. Because counstruction is in circular arch with small radius, it is necessary to contain real geometry to computational model. Model is created by beams and construction stages are included too. The construction is assessed for the ultimate and serviceability limit state according to valid standards. In the thesis is performed eigenvalue analysis and harmonic response of the construction. Detailed drawings are included too.

Pedestrian bridge over the Svratka river in Brno
Škrabal, Jan ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The subject of this bachelor thesis is the structural design of a one span pedestrian bridge over the Svratka River in Brno. The arch bridge with axially suspended deck on a steel arch was chosen for the assessment out of three options. It is a self-anchored structure, so that the tensile force in the deck must be eliminated by prestressing. For the calculation of internal forces the Scia Engineer 18.1 program was used. Two models were created – one for the longitudinal direction, the second one for transverse direction. Structural design was handled according to the valid standards and regulations.

Prestressed frame concrete structure
Duranová, Anna ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The Bachelor Thesis deals with designing a single-span frame structure over the riverbed, specifically a bridge for pedestrians and cyclists. Three studies of the single-span bridge, including their evaluation, were carried out. Subsequently, the variant of the single-span frame bridge with a parabolic deck was selected and drawn up. Dimensioning of the prestressed concrete deck and the reinforced concrete props was performed according to the limit states. The load effects were processed in the Scia Engineer software, and the calculations were made in MS Excel. The calculation procedure adhered to valid standards and regulations.
