Influence of aging on sandwich materials properties
Smékal, Aleš ; Löffelmann, František (referee) ; Klement, Josef (advisor)
The first part of the master’s thesis deals with sandwich materials. Starting with composition of parts which the sandwich panel is made of. The thesis continues with loading distribution and testing of entire sandwich panel. The impact of environment is considered as well. The second part is its goal – determine degradation of the properties of sandwich panels with metal sheets and core after 15 years aging in the common atmosphere and aging in moistheat and salt environment by experiment.

Sandwich structure application on the formula car
Žídek, Tomáš ; Cejpek, Jakub (referee) ; Löffelmann, František (advisor)
The master thesis describes application of a sandwich construction for Formula Student car. It will replace the current tubular space frame according to FSAE rules. The introduction is focused on the information of international Formula Student competition, including TU Brno Racing Team. Then there are important rules for the construction of frames and composite monocoques. For the selected production technology are found strength properties of face sheets made of carbon and hybrid fibres. Another part of thesis deals with the design of the sandwich panel using analytical calculation to determine the bending stiffness. On the basis of these proposals are made three-point bending and shear tests. Using of FEM simulation is detected torsional stiffness of the tubular space frame and the monocoque concept from the proposed sandwich panels. The conclusion is devoted to a summary of the important information and possible monocoque manufacturing process.

Car dealership with auto repair shop
Wilkonský, Roman ; Vašíček, Vladimír (referee) ; Kacálek, Petr (advisor)
This diploma thesis is being solved for documentation of building in the stage of execution. The building is designed as a showroom with car repair shop. The building site is located in the land registry of Ostrava – Vítkovice. Project documentation is designed accordingly to the valid Czech Republic’s laws, bills and building standards. The building is divided into two objects the first one is showroom with administration and the second one is the car repair shop with washing room and restrooms. These two objects are structurally and operationally connected. The largest plan dimensions are 68,56 x 38,36 m. The building is designed as a reinforced concrete frame in the administrative part and a reinforced concrete wall system in the car repair part. The roof is in both cases realized by using steel trusses. The reinforced concrete frame is lined with aerated concrete masonry. In the roof part it is cladded with sandwich steel panels. The building is founded on reinforced concrete foundation pads with combination of strip foundations. The car repair shop is designed as one floor building, whereas the administrative part is designed as two floor.

Multifinctional gym hall
Holemy, Ondřej ; Párová,, Jitka (referee) ; Rusinová, Marie (advisor)
The master‘s thesis concerns about the freestanding multipurpose sport hall with a base for sportsmen and spectators and its associated sport and regeneration centre. The object is situated in a city district Brno Bohunice. The designed building is divided into a single storey multipurpose sport hall and an outbuilding with two above-ground floors and a partial third floor above the entrance part of the building. Object’s plan shape forms a rectangle with recessed entrance part. The load-bearing structure consists of a combined column and wall construction system. The main multipurpose hall is roofed with arched glulam laminated trusses, which are supported by steel columns covered by sandwich panels. The outbuilding’s vertical load-bearing structure is formed by clay blocks. The horizontal load-bearing structure is formed by prestressed concrete floor slab. The building is based on shallow foundations. The object is designed to be barrier-free for sportsmen and visitors as well.

Administration Building
Frieda, Jan ; Pilgr, Milan (referee) ; Sýkora, Karel (advisor)
This thesis aims to design a bearing composite steel structure for five-storey administration building with ground plan dimensions 35,00 x 50,00 m. Designed building has L-shaped plan, flat roof and attic all the way around. The largest part of the plan area occupies office zone with dimensions of 48,60 x 18,90 m. Contiguous zone communication and sanitation has dimensions of 13,50 x 15,90 m. Floor height is designed 3,60 m, the total height of the building is 18,70 m. Composite steel floor structure consists of transverse primary beams and hinge-connected secondary beams. Integrated formwork (trapezoidal sheet) has ribs oriented perpendicular to the secondary beams. Coupling is bidirectional. Construction will be done in two variants. Variant No.1 assumes primary and secondary beams (at the columns) hinge-connected with columns. In variant No.2 will be frame connection between primary beams and columns and together they will create 2D transverse frames with hinge-connected secondary beams. The supporting structure of the roof is designed similarly to ceiling, but reinforced concrete slab will be replaced with bracing in the roof plane and self-bearing rib sandwich panels. Vertical sheathing of the building provide sandwich panels and strip windows. The type of steel is S355. The building is designed for the site Hradec Králové. Standards and documents used in design of the bearing structure are included in the list of sources. The result of this work is a static analysis with an assessment of all elements of the selected (best) variant of the structure, drawing documentation and technical report.

Space structure of industry building object
Pelikán, Adam ; Švaříčková,, Ivana (referee) ; Šimůnek, Petr (advisor)
The subject of this project is the structure of the storage hall which is made of reinforced concrete. It is designed as precast frame (span of 18m), founded on pocket footings. The roof deck (non-rigid) consists of ribbed slabs. The cladding is made of sandwich panels (reinforced concrete and isolation) layed on foundation beam. The design is focused on the single typical frame. Roof girder, column and pocket footing are designed. Designed life of the structure is 50 years.
