Reconstruction and strengthening of reinforced concrete ceiling construction
Klimeš, Petr ; Zich, Miloš (referee) ; Perla, Jan (advisor)
The final thesis deals with strengthening of cast-in-place concrete ceiling in existing construction for couple of escalators. New prestressed beam, columns in new positions and strengthened girder with unbonded strands are building in this adjustments. Every member, including the existing construction, is verified for ultimate and serviceability limit state. Prestressed members are alternatively designed with bonded strands and these variants are comparison in terms of utilization and calculation.

Overpass bridge across the highway
Černý, Pavel ; Šopík,, Leonard (referee) ; Nečas, Radim (advisor)
The topic of this thesis is detailed design of the supporting structure of a bridge. Three variants are designed. The structure is designed as a single beam bridge of 6 spans. The calculation of load efects make in software MidasCivil 2019 and Scia Engineer 18.1. The subject of the expertise of the structure is service limit state and ultimate limit state. For evaluation of cross sections is used MS Excel. Both design and relevant drawing documentation of the bridge deck and substructure. The design and assessment are according to the europien standards.

Pedestrian bridge over the Jihlava river in Třebíč
Vavřička, Lukáš ; Velešík, Marek (referee) ; Koláček, Jan (advisor)
The bachelor thesis deals with design of concrete pedestrian bridge over the Jihlava river. At the beginning two variants were created, one of which was future postprocessed. The cable-stayed construction, whose main support part is created by two pylons fixed to post-tensioned bridge deck, is pin-supported on abutment. Suspension of the deck is implemented by cables pin joined to the top of towers and sides of the deck. Material of the main concrete load-bearing structure is concrete C45/55. The steel elements of structure are made from steel S355, suspenders are designed with steel Macalloy 460. The structural assessment report was processed mostly by hand calculation with use of program MS Excel, for structural check of pylon use of program FIN EC beton was chosen. The load calculation was performed with program Scia Engineer. The drawing was created in AutoCAD software and the visualization in Lumion.

Bike bridge over the Nitra river
Teplanová, Alžbeta ; Páleník, Petr (referee) ; Koláček, Jan (advisor)
The subject of the diploma thesis is the design of variants of the construction of a footbridge for pedestrians and cyclists over the Nitra River. Two variants were created. After the comparison, a variant of the suspended footbridge was selected, which was modeled using the Midas Civil program and then statically assessed. The footbridge consists of a monolithic deck made of prestressed concrete. The pylons are located on one side of the bank

Plan curved cable stayed pedestrian bridge
Müller, Radek ; Kaláb,, Pavel (referee) ; Koláček, Jan (advisor)
In my thesis, I created a study of plan curved cable stayed pedestrian bridge. As the main construction material is used prestressed concrete. Suspenders and railing are made from steel. The footbridge has a length of 130,00 meters and a width of 3,70 meters. The plan shape of the structure is composed of two oposite arches. Bridge deck is made of box girder. The bridge deck is single-side suspended on two concrete pylons with a height of 39,00 m. Pylons are supported by suspender.

Design of a railway frame bridge
Findura, David ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of a two-track railway frame bridge over a valley. Out of three proposed variants was chosen the variant number 1 - prestressed frame construction with variable beam section. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.

Plan curved pedestrian bridge
Lachová, Alžběta ; Jurík,, Michal (referee) ; Koláček, Jan (advisor)
The subject of this master thesis is the elaboration of a study of a curved footbridge leading over the Svratka River. Two variants were created, from which a suspended structure was selected for subsequent modelling and assessment. The footbridge consists of a monolithic bridge deck made of prestressed concrete. The cross section of the bridge deck is designed as an asymmetrical box girder, suspended on one side by a pylon. The pylon is located on the inner side of the bridge deck at the junction of the apex and the centre of the circle and is anchored by hinges to the subgrade.
