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.

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.

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.
