Footbridge
Smělíková, Petra ; Puchner, Josef (referee) ; Sýkora, Karel (advisor)
The topic of my Bachelor's thesis is a static assessment of a bearing structure of a current footbridge which is also used for cycling. It is placed in Kunovice near Uherské Hradiště. The length of span is 28 meters. Its construction is solved as space framework with through-span. Main beam is truss structure with upper saddle flange. The height of beam in the middle of the span is 2.5 meters and above supports is 1.5 meters. The calculation is done either by hand or using calculation program Scia Engineer 2012.0.

The two-track railway bridge
Loučka, Miroslav ; Karmazínová, Marcela (referee) ; Puchner, Josef (advisor)
Master´s thesis describes the design of the railway bridge in Ústí nad Labem. Length of the structure is 200.00 meters, the height of the structure is 32.61 m and width of the structure is 12.10 m. Main structural system is composed of a spatial strut-frame structures. The bridge carries an important railway stations between Usti nad Labem Západ, Usti nad Labem Střekov. Part of the proposal is a footbridge for pedestrians.

The roofing of a railway station
Olbert, Jan ; Šmak, Milan (referee) ; Puchner, Josef (advisor)
The goal of this thesis is structural design of railway station lobby steel roofing. The construction dimensions are 63,0 m x 300,0 m with height adapted for railway vehicles traffic according to ČSN 73 6320 technical standard. The two-bay hall cross coupling consists of lattice trusses mounted on restrained columns. Axial spacing between individual bonds is 4,0 m. In the longitudinal direction the stability of articulated columns is secured by truss bracing placed in the roof and walls.

The roof structure of a storage area
Kuběna, Kamil ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
My task was to design and consider the carrier of steel structures for roof storage area in Brno, so that the structure meet all the requirements for buildings and fulfill its function. Roofing, with grand-plan dimensions 50 x 20 m clear height of 4,5 m. Cross sections of the main elements were proposed and considered and also selected joints and details of the structure. Assigned drawings are included in attachments of the thesis.

Sports hall
Hellebrand, David ; Puchner, Josef (referee) ; Sýkora, Karel (advisor)
This bachelor’s thesis deals with a project of roof load-bearing structure of a sports hall situated nearby the city of Opava. The sports hall would be designed for common sports such as handball, football, tenis, voleyball or basketbal. Groun plan scantlings of the con-struction are of 36 x 48 m and clearance of 8 m. Hall travers bond is composed of 3 m high lattice frames that are hinge-connected to a housed joint. Accouplement between the sup-porting lattice frames is done due to longitudial effective purline which continue to the wall-mounted parts of the structure. Spatial rigidity is made safe due to sway bracings and purline.

The roof structure of a multipurpose hall in Poděbrady
Houška, Daniel ; Puchner,, Josef (referee) ; Šmak, Milan (advisor)
The aim of this the bachelor thesis is a design of the supporting steel structure of the roofing for the multi-purpose sports hall in Poděbrady. Since a wide range of sports will be played in this sports hall, its layout and ground clearance are proposed accordingly. Prefabricated bleachers, which were not the solved in this thesis, will be part of the hall. Supporting facilities for the hall are located in the nearby buildings. It’s a single steel rectangular hall with a cylindrical roof. Curved beams were used as supporting elements. The beams will be filled with rods installed in a perpendicular system. For a structural analysis Sci Engineer 2011.1 was used. Selected elements were assessed by manual calculation.

Influence Selecting the Type of the Bridge Structure at km 332,420 of Railway Dětmarovice-Český Těšín by the Effects of Undermining
Chaloupka, Martin ; Puchner,, Josef (referee) ; Kmošek, David (advisor)
The aim of the master’s thesis was t odevelop alternative solutions supporting steel structure of the railway bridge on the undermined area. The range of single fields were chosen based on the location of existing substructures. Reducing the width of bridge openings were not allowed. Based on the geodetic survey plans were drawn up clear of the current state. On the basis of specifications for developing a detailed process was chosen variant Gerber’s beam reinforced with an arch in mean field. For this variant was performed structural analysis of the main parts of the main structure of the bridge, which was calculated with the effects of undermining. For variant Gerber’s beam were made clear drawings and drawing details of the selected steel bridge construction (new state). Further, detailed analysis of selected structural detail was made. Specifically, connecting rod to the main beam, which was designed optimal shape and thickness of the joints plate with a suitable radius of the firing to avoid plastification of the material in this area. Variant of the continuous beam without joints was prepared to. It has been observed, what is the effect of undermining on the stress in the construction of the bridge - was confronted with the effects on Gerber’s beam. To reduce stress in the construction of the bridge and compliance of ultimate state of applicability of the main beam has been designed bearing adjustment and after considering several options its implementation too. The economic comparison between the two variants was conducted. The assembling procedure was designed for both types of bridge structures. In the technical report we can read about due to the intention of building a new bridge and further we can find there other important technical information. In conclusion of the master’s thesis there has been recommended for the construction specific variant – from the perspective of an investor, and from the static aspect-view of the designer.

The pavilion in the zoo Lešná
Petrík, Tomáš ; Puchner, Josef (referee) ; Šmak, Milan (advisor)
The subject of the diploma thesis is a processed design of a steel construction of a pavilion shaped by spherical segments. The pavilion has exhibition purpose as a part of the zoological garden Lešná, and is intended for African beasts. The design meets architectonical requests - roundness and luminosity. A shape of the pavilion consists of three intersecting cupolas with a frontal curved cut out for glass facade. Construction of the pavilion consists of the radial arranged arched ribs with transversal bars, which are supplemented by horizontal purlins. Forehead of the pavilion is formed by columns and girts. Cladding is designed in combination: aluminum profile and insulated glass. Comparison of alternative steel structure solutions is also a part of the diploma thesis.
