Este trabalho abordou o estudo de ligação viga de aço e pilar misto preenchido com concreto a partir da aplicação de modelos numérico para representar o comportamento de duas tipologias de ligação: uma ligação parafusada com aderência entre os parafusos passantes e o núcleo de concreto e uma ligação soldada, validadas com base em resultados experimentais existentes. Os resultados obtidos nessa etapa foram considerados satisfatórios, dentro da proposta de modelagem, apesar das simplificações adotadas. Após a validação do modelo numérico foi desenvolvido um estudo paramétrico dos modelos de ligação para entender a influência de alguns parâmetros no comportamento global da estrutura, que foram: resistência à compressão do concreto e espessura do perfil tubular e perfil da viga, com posterior discussão da relação momento-rotação das duas tipologias de ligação estudadas. A mudança do perfil da viga foi o parâmetro que mais influenciou no comportamento global da ligação parafusada; enquanto que, para a ligação soldada, as variações de todos os parâmetros influenciaram no comportamento da ligação, com destaque para a variação do perfil da viga. / This research studied connections typology between steel beams to column filled with concrete from the application of numerical models that reproduce the behavior of two connections: bolted beam-column connection and welded beam-column connection, which were calibrated using existing experimental results. At this stage, the results were considered satisfactory, within the proposed model, despite the adopted simplifications. After the calibration, a parametric study was developed with the aim of verifying the influence of some parameters on the overall behavior of the structure, such as the concrete compression strength, the thickness of the tube wall and the beam properties, with discussions of bending moment-rotation of the studied connections. The beam properties were the parameters that most influenced on the overall behavior of the bolted beam-column connection, while, for the welded connection, all parameters influenced on the overall behavior of the connection, specially the beam properties.

This master thesis deals with design of a load-bearing steel structure, i tis located in ZOO Zlín areal. The building serves as a glasshouse. It is a single-storey building with circle plan, 39,04 m diameter and 15,63 m height. Space construction follows spherical cap of a sphere with diameter 40 m. Variant A building is design as a fuller dome. Variant B building consists of hexagons, which are getting smaller with height, at the upper part is the hexagonal geometry cancelled and geometry made from triangles follows. This thesis contains design of a pedestrian bridge, which carries all technical loads. The thesis contains static report of the beams a design of main joints.

The subject of the diploma thesis is design and structural analysis of the sports hall. The building is located in Pardubice city. The dimensions of a floor plan are 45,5 m x 30,0 m, the height is 13,0 m. There is a sport facilities unit adjusted to the construction. The dimension of such an object is 39,0 m x 10,0 m. The load-bearing structure consists of truss girders, which are pin-supported by fixed columns. The distance between main trusses is 6,5 m. The supporting part of the roof deck consists of solid-purlins. Space stability is ensured by cross bracing and longitudinal bracing. All bars are rolled steel profiles and are designed according to current ČSN EN standards. Steel S355 is used as the construction material. In this work is processed a structural design report of main elements including connections and drawing documentation.

The aim of this diploma thesis is the design of the roofing of an ice hockey stadium situated in Žďár nad Sázavou. Plan view dimensions are 55 m x 77 m. The structural height of the roof varies from 10 to 17 m. The roof itself consists of pipe truss girders with a span of 55 m, which are supported by columns on each side. The girders are suspended by a load-carrying arch with a span of 96 m and a camber of 29 m through a system of pre-stressed cables. To determine the internal forces, structural analysis software Scia Engineer was used. Individual elements were then manually designed.

The subject of the diploma thesis is the design and structural analysis of an exhibition hall. The building is located in Brno city. The dimensions of a floor plan are 121,8 m x 66,5 m, the height is 17,75 m. The load-bearing structure consists of arched truss girders, which are pin-supported by fixed columns. The distance between main trusses is 8,7 m. The supporting part of the roof deck consists of solid-purlins. Spatial rigidity of the structure is ensured by cross bracing and longitudinal bracing. All structural members are made of rolled steel profiles and are designed according to current ČSN EN standards. Steel S355 is used as the construction material. This thesis consists of structural design report of main load bearing elements including connections design and drawings.

The aim of diploma thesis is to design steel roof structure of minimum dimensions 45 m x 50 m and minimum height 12 m. The plan of the building design has dimensions of 52,14 m x 70, 00 m and height is 18,68 m. The roofing was design as 3D truss girders with two lower chords and one upper chord. The shape of 3D truss girder consists of three circular arcs of radius 69,88m, 12,43 m and 33,45 m. Between main girders is 3D bracing. The structure is pin-supported.

This thesis deals with design of a multi-purpose sports hall. The aim of this work is to design a support structure with a diameter of 80.0 m at ± 0.000. Construction of a circular layout in the level of ± 0.000 of an external diameter 80.0 m. Height of the hall at the top is 20.0 m Indoors girders is solved in 36 beams which meet at the middle of the rings. Ensure the stability of bracing. Anchoring is done by pin connections located at the bottom of the strip, anchored in concrete bases through the base plate and pre-concreted anchor bolts.

The diploma thesis describes the design and assessment of steel structure of the roofing of the military museum in Králíky. The supporting structure of hall is 40.00 meters span. The total layout are 55.93 x 72.04 m, building height 11.43 m, 16.11 m pylon height. Main construction material is steel, grade S355, secondary constructions are made from steel grade S235, rods are made from steel grade S460. I did optimization of steel structure and chose the best option. For this option I made detailed structural analysis. It is prepared by static analysis of the main load-bearing parts of the structure, including joints and details. The supporting structure of hall consists in the transverse direction from the curved spatial lattice structure made of steel circular tubes which hang on rods on a sloped pylon. Part of the report is open-air roofing.

The diploma thesis elaborates on the proposal of a loadbearing steel structure of a shopping centre. Four-storey building has total lenght of 88 m, width 48 m and its base structural grid is 8 x 8 m. The total height of building is 25,4 m. First three floors above ground are designed with structural height of 5,6 m whilst the 4TH floor uses height of 4,0 m. Frame structure is formed by primary beams and castellated secondary beams. Above 4TH floor, the roof structure is designed in two alternative versions, both using solid purlins and truss girder. The 3D computer animation of the building is also part of thesis. The shopping centre that is subject of the final thesis is located in Brno area.
