Design of steel-concrete composite structure of road box girder bridge on by-road of Bludov
Kuba, Michal ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of this work is design and assessment of the box-girder road bridge on by-road of Bludov. Bridge is designed as composite steel concrete bridge with 5 spans with distances between supports of 31,25 m; 40,0 m; 60,0 m; 60,0 m and 40,35 m. Main bearing structure is designed as open steel box-girder with reinforced concrete deck. Box girder is braced with longitudinal and transversal bracings. Main structure is separated for each traffic direction. The bridge crosses river Morava and railway in 2nd and 3rd span, respectively. The category of road I/44 is S 21,5/100. The height of steel box girder is designed as 2,5 m. Bridge will be built by incremental launching method, with in-situ casted concrete deck afterwards. The bridge is designed according to current standards. Supporting elements are designed from steel of class S 355 and concrete of class C35/45.

County library in Havlíčkův Brod
Sommer, Miroslav ; Röder, Václav (referee) ; Šmak, Milan (advisor)
The work is treated as a steel construction multi-storey buildings in the county library Havlickuv Brod. At design requirements were respected in shape and layout of the building. The complex consists of three parts - two, four and five floors. The overall footprint is about 85 x 32 m. The proposal is designed as a composite steel and concrete slab. Pent roof construction is inclined 5 degrees. Anchors are designed as joint. Horizontal forces on the design of frames are transmitted in both directions.

Design of steel-concrete composite structure of road bridge in Trenčín
Doležal, Tomáš ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of diploma thesis was to design alternative of composite road bridge in Trenčín. The bridge beam is designed as continuous with theoretical span of 65 m + 106 m + 65 m. Permanent load, climatic load (uniform and nonuniform temperature variation, windload), shrinkage, differential settlement and traffic load were taken into consideration according to Eurocodes. Technical report, static report, drawings, bill of quantities are included. Computational model for evaluation of internal forces was carried out in SCIA Engineer software.

Shopping Centre
Altoff, Tomáš ; Štrba, Michal (referee) ; Pilgr, Milan (advisor)
This diploma thesis is deals with design of steel structure of a shopping centre. The object is situated in the Ostrava and has a rectangular and semicircle ground plan. The total ground plan dimensions are 72,5 x 55,0 m. The maximum height of a building is 18,75 m. The object has three storeys above ground. The material of main construction is steel grade S235. The ceilings are constructed from a steel-concrete beams. The roof above central part of the object has shape of a circular arch; above the other part of the building is a pitched roof. The design of main structures was made for two variants. The design of connections, anchorage and drawing documentation were made for the preferable variant.

Eddy Current Probe Design and its Application on Aircraft Composite Structures
Boháčová, Marie ; Hájek, Karel (referee) ; Kopec, Bernard (referee) ; Mazal, Pavel (advisor)
This thesis deals with design of an eddy current transducer which enables non-destructive inspection of composite aircraft structures primarily carbon fiber reinforced plastic (CFRP) in areas of manufacture and maintenance. The design of the transducer is based on analytical-experimental approach and its electrical and mechanical parameters were optimized to ensure a good signal to noise ratio at the six composite samples. These samples contain artificial discontinuities in the form of various types of defects. These defects are simulating the various types of damage created in the aircraft structure, especially delamination or thickness changes of composite materials. The experimental measurements, data collection and non-destructive evaluation were performed during the period. The result of this work is functional eddy current probe, which is reliably able to detect some damage of the carbon composite structures to the depth of 3,9 mm.

Administrative Building
Vokatá, Kateřina ; Barnat,, Jan (referee) ; Bajer, Miroslav (advisor)
This diploma thesis is deal with design of steel structure of office building. Layout of building is rectangular with dimensions 45x34m, with one storey below earth and five storey above earth. Height of building is 21,5 m (from ground). The main structure of building is created by nine steel frames in cross direction. Between frames are inserted composite steel and concrete beams. The roof is flat. The surface of facade is glass created by aluminium structure with columns and rails.

Office building
Závacká, Petra ; Barnat, Jan (referee) ; Bajer, Miroslav (advisor)
The final product of my thesis is a design of a bearing steel construction with conjugated concrete-steel elements horizontally attached to an administrative building. The thesis contains a desing of an administrative building with a parking garage which are connected. The administrative building has 8 floors and the parking garage with the connecting part has 4 floors. The height of the floor in all objects is 3,5m in 1.NP. From 2.NP up each floor has a height of 3m. The administrative building has a rectangular shape with dimensions of 36 x 48 m. The parking garage is of similar shape with dimensions of 30 x 54 m. Both buidlings are joined in an angle of 33 deg. The height of the administrative building above ground is 26, 475m. The height of the parking garage above the ground with the connecting part is 12,795m. The structure is made up of articulated beams stored in the column. Composite cross section is stored on girder hinge. The design of both objects is stiffened by vertical wall braces the transverse and longitudinal directions. Roofs are a mixture of objects for a specified period. The office building is located atrium measuring 12 x 24m. Atrium roofing is made by steel structure with glass panes. Cladding will consist of building glass facade.

Possibility of using of fibre-concrete at composite steel-concrete structures
Pozdíšek, Jan ; Karmazínová, Marcela (advisor)
The aim of the offered thesis is an analysis of usage of uncommon concrete matrix and its contribution to steel-concrete composites structures. It especially refers to the area of internal supports, where usually acts negative bending moments. These statical systems are very often used for bridge structures, or even for building constructions. Nowdays, the static infuence of concrete at the area of negative moment is neglected. Only the steel part of cross section and steel reinforcement are included to the static action. This work is focused on the usage of tensile strength of uncommon concrete. The improvement of tensile strength of cement matrix is due to glass fiber reinforcement acting as scattered reinforcing. The introduction is focused on common approach of design of the structures mentioned above. Next, there is a part which describes possibilites of using fibre reinforcing until nowdays.

Symonov, Volodymyr ; Halama, Radim (referee) ; Píštěk, Antonín (referee) ; Juračka, Jaroslav (advisor)
Disertační práce se věnuje vývoji metodologií pro vice-cílovou optimalizací složitých kompozitních konstrukcí s proměnnou tuhosti. Vice úrovňový hybridní optimalizační algoritmus je založený na bázi hybridní optimalizační metody s využitím interpolační plochy odezvy, genetického algoritmu a jednoparametrické optimalizace. Pro strukturální analýzy je využit MKP software MSC Nastran. Nový genetický algoritmus a paralelní jednoparametrický optimalizační algoritmus na základě metody Zlatého řezu jsou vyvinuty pro metodologii. MKP software a vyvinuté optimalizační algoritmy jsou integrované pomoci komerčního optimalizačního softwaru Noesis Optimus od Noesis Solutions. Vyvinutá metodologie je ověřena pomoci testovací optimalizační úlohy.
