Prestressed bridge on the expressway
Juřenčáková, Jana ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The purpose of the diploma thesis is to design a expressway bridge over the river Vsetínská Bečva. The bridge is located between Valašské Meziříčí and Vsetín. Separate superstructures are designed for each directions of the expressway. The right superstructure, which is wider, is considered for detailed design. Two variants were proposed, A double T beam superstructure and a box girder superstructure. The three span box girder superstructure was chosen for the design. Spans are 48+65+48 m long. Two options of construction process of the superstructure were proposed. This bridge is designed according to the limit states, the influence of construction process is considered. Structural models of construction were made as a finite element model and a plate model. Structural analysis, drawings and visualization were developed.

Multi-span double teebridge
Alušic, Michal ; Řeřucha, Kamil (referee) ; Koláček, Jan (advisor)
Main purpose of the diploma thesis is to design a multi-span double-girder bridge which spans the valley of a river. The bridge spans main road of 1st class. Main superstructure of a bridge is made of prestressed concrete which is built span by span. Structure was designed according to limit states in construction stages as well as during the service. Everything was designed according to the latest European normatives. It contains static calculation and drawing documentation.

Bridge on I/38 road.
Novotný, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The final thesis is focused on design of valley bridging on I/38 road at the Havlickuv Brod bypass. The thesis contains study of the bridging area. For detailed assessment was chosen, from three variants, a two-beam cross-section girder of 4 spans. Load-bearing structure is designed as cast-in-place, post-tensioned, concreted at fixed falsework without phased construction. The serviceability limit state and the ultimate limit state were assessed. The thesis contains, apart from structural design, drawings and visualizations of the bridge.

Analysis of cantilever of commercial building
Gric, Pavel ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
This diploma thesis is about analysis of post-tensioned cantilever beam, which is part of cantilever of commercial building. The main part of thesis is evaluation of behavior of building structure in time and determination of the most suitable staging. Next part of thesis is design and evaluation of reinforced slab and beam.

The concrete structure of a high office building
Skuhravý, František ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
Aim of The Diploma Thesis was to design load-bearing structure of a multi-storey reinforced concrete building, to realize structural analysis in Dlubal-RFEM software and dimension its selected parts. Designed structure is based on already erected building in office edifices campus in Brno-Slatina district. Its original number of storeys was increased from ten to nineteen, so the specific problems connected to high-rise building designing could be solved. Time dependent deformations of vertical structures were analysed in detail, so the changes in load of horizontal elements could be described more precisely, because of its direct dependence on compression of the columns. Within the paper, foundation structure dimensions were designed, assessment and design of composite columns assembly were made, as well of floor slab in 2nd floor with column deformations impact check on the 17th floor. Also, the external walls, pillars and shear core walls were designed and assessed. Formwork drawing of designed structure parts and detailed drawing of reinforcement of assessed elements were elaborated. Based on Diploma Thesis results it can be stated, that if influence of nonuniform load of vertical structures within the high-rise building designing is neglected, consequent project would presumably be uneconomic, or dangerous after an optimization attempts.

Prestressed bridge No. 202 on the expressway R2 in Slovakia
Janek, Tomáš ; Urban, Jiří (referee) ; Koláček, Jan (advisor)
My diploma thesis deals with design of the bridge number 202 on expressway in Slovakia. The bridge leads across the road number I50 (between Trenčín and Bánovce nad Bebravou) and railway number 130 (between Trenčín and Chynorany). For each course there is a separate super-structure. Only left super-structure is considered for the work. The box girder with four spans is chosen from three variations. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural model of construction is made as a spatial bar model. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

Prestressed box girder bridge
Štíchová, Kateřina ; Štefan, Petr (referee) ; Koláček, Jan (advisor)
The subject of this diploma thesis is the design of a load–bearing structure, whitch is situated in the extravillain between the town of Chomutov and the village Křimov. Main purpose of this structure is to pass a roadway I/7 across the valley. There are three options of design and one of them – the prestressed box girder bridge with slanted walls is chosen for more detailed elaboration. The major load–bearing structure is five–span with lenghts 46.50 + 58.00 + 58.00 + 58.00 + 46.50 m, made of post–tensioned nad cast–in–place concrete. The total lenght of load–bearing structure is 269.00 m and the width of load–bearing structure is 13.50 m, the bridge is straight in plan. The structure is analyzed by several computational models, which are designed in Scia Engineer 20.0 software. The structure is analysed in longitudinal and cross directions. The assessments of load state limit and usability limit state are made according to valid standards. This thesis also included time dependent analysis (TDA), that takes construction stage analysis into account.

Bridge over the Živný Brook
Sekanina, Josef ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
This thesis occupies with the design of the road bridge over the stream Živný, a railway lane and a projected road between Běleč village and Husinec village. There are designed three variants of bridges. The variant no. 1 – continuous box girded beam – was chosen for the detailed analysis. The pre-stressed concrete road bridge is designed and evaluated according to European standards – Euro codes. The sequential construction influence and its impact on the construction is also considered in the calculations. The drawing documentation and the visualization of the bridge are made.

Bridge over the Berounka river
Gratza, Jonáš ; Diviš, Dalibor (referee) ; Panáček, Josef (advisor)
Diploma thesis is focused on a design of the road bridge in Roztoky municipality. The bridge spans Berounka river. The design is processed in three options and the selected option was developed in greater detail. The layout of bridge is designed as a girder box with haunch. The bridge will be built by a cantilever erection method. Structural analysis of the bridge regards the influences of construction by TDA method. The structure is assessed for temporary and permanent states. The assessment of the structure was made according to EC.

Static solution of reinforced concrete structure
Mašek, Petr ; Kostiha, Vojtěch (referee) ; Zlámal, Martin (advisor)
This diploma thesis deals with study of feasibility of waterpark monolithic reinforced concrete structure with roof terrace. This structure has one underground floor, which has water park utility function and two above ground floors. On the roof is terrace with grass, mobile bar and with space to relax. Subject of this diploma thesis is the main loadbearing frame, which has span 32 m. The structure is assessed according to limit states of valid norms and also takes into account construction stages and time dependent analysis. The structure is calculated on beam and slab-plate structural models. Structural analysis and general drawings are done.
