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.

Motorway Viaduct
Polách, Marek ; Šopík,, Leonard (referee) ; Stráský, Jiří (advisor)
The thesis is a design of a bridge crossing the valley of the Hrabyňka creek as a part of road I/II. Firstly, three possible structures are designed and according to their advantages and disadvantages, the best of them is selected. In this case a cable stay bridge was selected. Following is a design of span lenghths, collumn heights and the cross-section. Then the loads are detremined and applied on a numeric model cretaed in software working on the basis of FEM. In continuation internal forces are calculated and their propriate combinations for service limit stay and ultimate limit state with time dependent analysis taken into account. In the end the reinforcement steel is designed for one part of the structure. Detailed drawings are also part of the thesis.

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.

London Eye
Hušek, Martin ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
Performance of static analysis of the London Eye structure is the subject of this diploma thesis. First chapters of the thesis analyses overview of realized structures of the Ferris wheel. The main part of the thesis analyses the London Eye structure itself. Specifically are described response analyses, sensitivity analyses, analyses of ultimate limit state and serviceability, stress analyses, analyses of fatigue stress and lifetime analyses. The thesis describes among static analysis also a design of dynamic vibration absorbers. The results of each analysis are evaluated in the final chapters.

Diagnostic and Reconstruction Design of Brick Building in Medlice
Košárek, Jan ; Cikrle, Petr (referee) ; Kocáb, Dalibor (advisor)
Master’s thesis deals with diagnostics and reconstruction of neo-gothic chapel in Medlice. Summary of appropriate testing methods for this chapel is compiled. Visual examination of whole structure have been performed by diagnostics. Masonry element strength was found out at specimens which had were taken out from structure (drill cores and whole bricks). Masonry elements also was tested by Schmidt hammer LB. Mortar was tested by Kucera’s drill. Masonry strength required for static calculation was computed from achieved values. After examination of all structure defects have been designed reconstruction by post-tensioning.

Design of reinforced tank
Štramberský, Martin ; Sliwka, Pavel (referee) ; Zich, Miloš (advisor)
The matter of this diploma thesis is a static storage tank for petroleum substances, the study of a solution for appropriate shape of shell and its effort to dihedral for roofing, and the study of effect of the storage of inner roofs walls of the tank to the size of the internal forces. The internal walls are carried out by the method of finite elements in the engineering program Scia Engineering 2013 and on the basis of it, designing of the framing sections of the tank. There is a calculation part of the lower horizontal bias wreaths of the shell and internal supporting wall. All the components are assessed on the 1st limit state of the load-bearing capacity and the 2nd limit state of the application (emergence cracks, limiting voltage in the concrete and a prestressing steel). The existing external wall is assessed only on the marginal status load of carrying capacity. The part of diploma thesis is also drawing documentation, accompanying report and technical report. The goal of the diploma thesis was to design the tank without an occurrence of the cracks in the concrete so as the vertical wall was prestressing only in the horizontal direction and the optimal proposal roof tanks as an addition.

Suspension footbridge across the river
Chumová, Petra ; Bartoň, Jaroslav (referee) ; Nečas, Radim (advisor)
The subject of the thesis is to design a suspension footbridge over a river basin. Three different studies were created for the assigned problem. The suspension footbridge was chosen for the thorough elaboration. The most important part of the thesis is the static solution of the supporting structure. The structure model for calculation of impacts of selected strains including the impact of the footbridge construction was created in computational software Ansys. Assessment and dimensioning was carried out using manual calculation according the principles of limit states and applicable standards.

Static and dynamic analysis of Prestressed bridge structure
Hokeš, Filip ; Nečas, Radim (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to perform static and dynamic analysis of prestressed concrete bridge structures in computational system ANSYS. For the analysis was chosen footbridge over the river Svratka in Brno. In relation to this topic are solved various types of modeling prestress at a finite element level. Before analyzing the footbridge is analyzed in detail the static system and the corresponding final geometry of the structure. Knowledge of the functioning of the static system is used to build the computational model of the structure, on which is subsequently performed static and dynamic analysis.

Static securing of church
Jelínek, Lukáš ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
This thesis addresses the static security chapel in Medlice. The chapel is a single-Gothic style. The other two dimensions 8x14 m chapels are part of the chapel tower is 20 m high with dimensions of 2,6 x2, 6 m Chapel was built in 1901. The truss chapel was damaged by pests, and therefore, a need to examine and exchange truss. On this occasion, establish a reinforced concrete ring that object until now lacked. In bearing walls of the chapel are visible cracks and occurs because the horizontal bracing object using a technology called monostrands.

Design of exhibition hall roof
Němec, Petr ; Ing.Paris Chalivopulos (referee) ; Zich, Miloš (advisor)
The Diploma’s thesis is focused on the design of selected parts of reinforced concrete exhibition hall (prestressed concrete purlin, prestressed concrete girder, reinforced concrete column, reinforced concrete footing, post-tensioned concrete girders). The load calculation (the self weight, the permanent load, the wind load, the snow load and imposed load), the design and the review of selected reinforced concrete items and the drawing documentation are included in this thesis.
