Pedestrian bridge across the river Jihlava
Ondřej, Václav ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this bachelor thesis is design of pedestian bridge across the river Jihlava. Out of three proposed variants was chosen frame construction. Calculation of load cases was made in software AxisVM and MS Excel. The construction was designed and assessed to the ultimate limit state and the serviceability limit state. The calculation was made according to valid standards.

Analysis of the wind effect on the construction
Tačner, Jan ; Hradil, Petr (referee) ; Kala, Jiří (advisor)
Diploma thesis deals with static and dynamic analyses of a slender bridge structure behavior. The footbridge structure model was created in ANSYS 14.5 programing system. Static and a modal analyses were made afterwards and according to these analyses dynamic wind load and dynamic pedestrian load were applied. Wind load was applied as option of deck without a handrail and as option of deck with fully airtight handrail. Pedestrians were perceived as group of pedestrians and as a sparse crowd. Both applied loads were solved by harmonic analyses. Results of these analyses are resonance curves and tables of accleration.

Sports and Leisure Centre Brno
Chovanečková, Nikol ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
The theme of the dissertation titled the Centre of Sport and Leisure Time in Brno is a design of a relaxing and sport site „Centrum Lužánky“. The subject of this project is architectonic-city-planning study, which deals with elaborating a concept of a sport centre behind Lužánky in Brno-Ponava. This dissertation contains details of the facility and the area of the current swimming pool Lužánky. The current state of the facility built in 1979 doesn’t meet requirements of visitors and sportsmen anymore. The main aim of this project is the reconstruction of the current fifty-meter swimming pool, a design of a new swimming pool placed under the ground floor of the current building, which will provide space for organizing international competitions, trainings of professional sportsmen, etc. At the same time the busyness of the current swimming pools would be lowered by building a new indoor and outdoor waterpark, especially for the group of recreational visitors. The attractiveness of the facility will be increased by the newly designed park relaxing area and proposed multipurpose area, used as a sports field in the summer and as an ice ring in the winter. Additional value of the facility is comprised by an indoor and outdoor café and large relaxing area on the roof of the waterpark. The whole area increases the community facility availability by a proposed wide range of services for health, relax and sport. The advantage of the whole concept is the mutual connection of all facilities. The entrance to the area is shortened by a designed pedestrian bridge, accessible from the south and north busy areas. The whole project is enhanced by increased number of new parking places, located particularly along the access road, the street Sportovní, going through a green zone. The road and parking places are proposed in the design of residential streets, respecting walking pedestrians. The area has a very rich sport history, which is dated back to 1922. The new concept increases th

Pedestrian bridge across the lagoon
Bezručová, Kristína ; Kaláb,, Pavel (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the lagoon. Three variants were designed. The variant of structure, which combines stress ribbon with steel arches, was chosen for analysis. There is a chapter in this thesis which deals with an ideal shape of arches for different types of loads. The calculation of load effects was made in software Ansys 17.0, considering scnstruction stages. Ultimate limit state and state limit state are evaluated. For evaluation of concrete cross sections was used MS Excel. Steel cross sections were evaluated in software Ansys 17.0. d Dynamic behaviour of construction was assessed. The mode shapes and natural frequencies were calculated. The harmonic excitation response was studied. The loss of stability was checked. The design and assessment are according to the european 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.

Reconstruction of the cable suspended footbridge in Kroměříž
Liška, Jaroslav ; Kulhavý,, Tomáš (referee) ; Klusáček, Ladislav (advisor)
The Diploma thesis deals with the reconstruction design of a footbridge in the city of Kroměříž, Czech Republic. The footbridge would serve as safe transport for pedestrians over the Morava river. The main objective of the thesis is to conceive two or three reconstruction designs. The most suitable one will be opted for and elaborated in more detail. Eventually, strengthening of the bridge by means of additional prestressing using mono-strand post-tensioning systems is picked as the best solution of the planned reconstruction. The monostrand post-tensioning system is led under the deck, the cross section being outside. External cables are anchored in concrete blocks built around existing supports. Load-generated internal forces are calculated on a spatial bar model with non-linear first-order analysis. The calculation is executed using the finite element method in the midas Civil programme. The chosen reconstruction design is then assessed against load capacity limit states, and functionality. Also, the designed reconstruction is assed for dynamic effects. Results are compared with existing structure, and verified against the real-time tensometric measurement-obtained data. Dimensions, assessment of load-bearing structure, and structural details are all made according to valid Eurocodes.

Pedestrian Footbridge over Railway Station
Hurych, Marek ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The diploma thesis deals with design of loadbearing stell structure of a footbridge across the railway station. Footbridge is situated in the city centre of Brno with total length of 135 meters. For comparison, three bridging variants are predesigned and a varints comparison is made. The selected option was developed in greater detail. It is an arched structure with a semithrough bridge deck and adjacent span with support of oblique column. The main loadbearing structure consists of a pair of pin-supported arches inclited to each other at an angle of 11°. Arches support beams with susperder, the beams are conected by ortotropic steel deck. All load-bearing elements are designed from S355 stell. Spatial rigidity of the structure is ensured by tilting of the arches and by truss bracing at the top of the arch in combination with rigid struts of arch. Spatial rigidity of the superted deck is ensured by ortotropic steel deck.

Footbridge over Úpa river in Trutnov
Výborný, Martin ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
The goal of this thesis was to design a steel structure of a footbridge for pedestrians and cyclists over the river Úpa in Trutnov spanning 20m. Also, it was calculated with a crossing of 3,5t vehicle. Preliminary design was carried for two variants. Variant B is truss structure, structure of Variant A is carried by prestressed cable and is further developed. Main structural beams of variant A are designed to be a shape of parabole with the middle beam connected by arbitrary profiled vertical beams to supporting prestressed high yield cable. For the design of structure, SLS was the main factor so elastic check is performed for ULS.

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.
