BRIDGE ON D1 (LIETAVSKÁ LÚČKA - VIŠŇOVÉ) OVER VALLEY AT km 4.313
Hudyma, Nazar ; Dvořák, Tomáš (referee) ; Zich, Miloš (advisor)
The subject of this Master's thesis is the design of a road bridge on the D1 in the section Lietavská Lúčka - Višňové in the Žilina Region, Žilina District, Slovak Republic. The bridge is used to cross the valley in KM 4,313 and the road in KM 4,410. Three variants of bridging were proposed, but further in the work an assessment is made on one of the variants. The total length of the superstructure is 354.00 m, the theoretical total span of the structure is 352.00 m. The bridge has 4 spans and is constructed by free cantilever method .The locations of the supports were limited by unsuitable geological conditions at the construction site (active shear area in Quaternary sediments), especially in span No. 3 (span lenght 104.00 m) and span No. 4 (span lenght 75.00 m). The monolithic part of the bridge structure will be concreted by free cantilever method with the largest length of the cantilever 52.00 m. The outermost parts of fields No. 1 and No. 4 will be cast-in-place using fixed scaffolding.

Bridge on a highway
Knotek, Jan ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
Subject of this bachelor’s thesis is design of new slab bridge construction over the II/464 road between the villages Příbor and Bílovec. The bridge converts highway D47. Thesis includes three studies. Pre-stressed rectangular cross-section slab with elliptical exterior trim, pre-stressed plate- grinder construction and construction of prefabricated beams and monolithic slab. For next assessment was chosen option no.1. Load effects calculation is solved in SCIA engineer 16.1. Design and assessment of the structure are made according to valid standards and regulations.

Bridge on the D1 highway over a road and brook
Surovcová, Monika ; Zdražilová, Magda (referee) ; Panáček, Josef (advisor)
The aim of the diploma thesis is the proposal of a bridge structure in the direction of Přerov – Lipník in the cadastral territory of the Osek nad Bečvou. A bridge is used to overcome the road III/43612 in km 93,550, the stream Lubeň and a field trip. From tree alternatives is selected a post-tensioned two-beam concrete struction and assessed according to the limit states including an impact of phased construction according to the European standards. Also it is prepared a drawing documentation, an accompanying report and a visualization of the beam.

D3 motorway bridge at km 33,588 in Slovakia
Lipovský, Václav ; Řeřucha, Kamil (referee) ; Koláček, Jan (advisor)
The diploma thesis deals with the design of a motorway bridge carrying the D3 motorway over a deep valley between Svrčinovec and Skalité. Three variants were developed for this work, from which the variant of a prestressed box girder bridge with sloping walls was selected for a detailed solution. The main superstructure was designed as a continuous structure with five spans of post-tensioned concrete. The superstructure is concreted in phases by means of an movable scaffolding system. The total length of the supporting structure is 255.50 m. The bridge is straight in plan. The analysis of the structure was carried out by means of several models that were created in Scia Engineer 21.1. The assessments of ultimate limit state and serviceability limit state were made according to valid standarts. The analysis of the structure was carried out in longitudinal and transverse directions. This thesis also includes a time dependent analysis (TDA) that takes the construciton phases into account. Finally, drawings and visualizations were produced.

Highway bridge over wide wally
Mertová, Eliška ; Smejkal, Ing David (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis was the design of three possible variants, how to span the wide and deep valley with a bridge. After an evaluation, situation of the highway on the only wide load-bearing structure which is constituted by a box girder with transverse cantilevers supported by prefabricated bar braces, was chosen as an optimal solving. The load- bearing structure made of post- tensioned concrete is going to be incrementally launched and be supported by one-column pillars along an axis of the motorway. The work is composed of a detailed design of this preferred variant, which is processed according to the ultimate and serviceability limit state including the construction stage analysis of the bridge by the construction technology by an incremental launching method.

Flyover bridge across the II/434 road
Russnák, Adam ; Neudert, Zdeněk (referee) ; Panáček, Josef (advisor)
Subject of this master thesis is a flyover bridge over the road II/434 and flood-land. As a load-bearing construction is designed two-beam structure. Traffic loads on this structure are considered according to standard ČSN EN 1991-2. The structure design is based on resultant stressing according to standard ČSN EN 1992-2.

Bridge No. 203 on the highway D1, Považská Bystrica
Mudrík, Marián ; Štrba, Michal (referee) ; Karmazínová, Marcela (advisor)
The diploma thesis deals with alternative design of bridge on highway D1 near Považská Bystrica. Bridge is designed as composite steel-concrete bridge with 6 spans in length 35,7m + 42m + 42m + 42m + 42m + 35,7m. Overall length of superstructure of the bridge is 241m. Construction material used in design is steel S355, concrete C35/45 and reinforcing steel bars are grade B500B. Calculation of superstructure of two variants was performed in preliminary design. First variant is twin-girder structure system and box-girder structure system is second variant. Selected twin-girder bridge was developed in more complex structural design report. Direct erection in place with temporary piers was selected as assembly method of steel structure. Slab concreting will be done by mobile formwork. The design and calculation of the bridge structure was carried out according to valid European design codes. The diploma thesis includes engineering report, structural design report of variants, structural design report of final variant, bill of quantities of assembly parts and drawing documentation.

Highway multispan bridge over wide wally
Bobek, Lukáš ; Daněk, Ing Stanislav (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis is to design and assess highway bridge. The structure is located on the D1 motorway section bridging a wide valley between the Slovak villages Doľany a Klčov. Three variants have been created – box girder bridge with transverse overhangs, a pair of girder bridge and a pair of box girder bridges. The various proposals were compared with each other. For the most valuable option is selected prestressed box girder bridge with transverse overhangs, which are supported by prefabricated concrete struts. The selected proposal was subsequently elaborated in detail, the load-bearing structure is analyzed using Scia Engineer 16. In calculating the internal forces is adjusted for the effects of construction methods, even as time-dependent analysis TDA. When designing the load-bearing structure it is considered the action of permanent load, also loading from transport and temperature. The structure is assessed for serviceability and ultimate limit states according to current standards. The bridge deck is built by incremental launching method. The principle of this method consists of building the segments in a casting yard located behind the bridge abutment. Each segment is matchcast against the previous one and prestressed to the section of structure already built. The whole superstructure is then jacked forward a distance equal to the length of this segment. This process is repeated until the bridge deck is in its final position. Chosen method of construction is very fast and efficient, to the country in the valley isn´t damage during construction.

Housing+
Doubrava, Šimon ; Jurkovič, Peter (referee) ; Galeová, Nicol (advisor)
A group of lots is located in a gap between a crossroad at Tomkovo square and the only natural solitaire nearby, Husovice hill. A newly-built highway bridge which is a part of outer Brno bypass unloads the street line of a big part of traffic load. Corner buildings, which stand between the bridge and the site serves as a noise barrier and together with the bridge, which moves the noise and vibrations to the upper levels change the site in a peaceful place. Calm character, the possibility to grab hold of the conection between Tomkovo square and Husovice hill and convenient commodity-monetary relations were three main reasons why the site was chosen for a proposal of dwelling complex.
