The Forest Viewtower in Beskydy
Kamrádová, Michaela ; Straka,, Bohumil (referee) ; Šmak, Milan (advisor)
Topic of this Master's Thesis is a design and a statical evalution of a load bearing structure of an observation tower in Beskydy mountains. Ground plan of this structure is in a shape of a nonagon with a non-roofed interior space. Height of the observation tower is 38,5 m, the shape of a ground plan doesn't change with a radius of a circumscribed circle of 12 m. The structure is designed from glued laminated timber, solid wood and steel. Columns bear horizontal beams and their stiffness is ensured by horizontal and inclined reinforcing beams. Main load bearing columns, upper and lower beams are designed from glued laminated timber GL24h. Upper beams and beams of a gallery are designed from glued laminated timber GL36h. Horizontal stiffener is designed from solid wood C24. Central column, inclined beams, stairway, water slide cantilevers, rod and central rod are designed from steel of a strength class S235. Cantilever for gallery is designed from steel of a strength class S355. Connections are designed from steel elements. Statical evaluation, technical report and construction drawing are included

The timber log cabin structure of the boarding house in Karlov
Špačková, Eva ; Straka, Bohumil (referee) ; Šmak, Milan (advisor)
The bachelor´s thesis deals with the design and the assessment of the wooden roof structure above the guest house in Karlov pod Pradědem, Jeseniky, at an altitude of 725 metres above sea level. The object has plan of the cross-shaped object about the approximate dimensions 13x20 m. On the first floor is brick. The second floor is made of wooden circular profiles – log cabin. The attic is habitable rooms, and I had to consider in the design of roofing. The roof structure is designed as a pair of intersecting each other pitched roofs. The emphasis is on the use of circular sections, to the roof of the extension on the bottom of the building, which is also from the circular profiles.

Exhibition pavilion
Španihel, Jiří ; Doc.Ing. Bohumil Straka,CSc. (referee) ; Sýkora, Karel (advisor)
The subject of the diploma thesis is design and examination of supporting steel structure of the exhibition pavilion situated at the Brno Exhibition Centre, including a comparison with the second variant. The design emphasis has been placed on keeping the architectural character of building related to its purpose. The structure consists of 11 sections shaped as elliptical arcs, formed by truss frames with variable length of semi-axes, while the largest size (the smallest) is 13 m (7 m) for minor semi-axis and 20 m (14 m) for the main semi-axis, height is 16 m (10 m) and distance of support 38.92 m (25.30 meters). For the analysis of internal forces has been assembled spatial bar shaped model. Cladding is made of Kalzip system.

Timber foot bridge over a wolf run
Mynaříková, Alice ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The subject of this diploma thesis is the construction of a timber foot bridge over the wolf run in the Šumava National Park. The total length of the bridge is 240 m with two ground plan bends. The foot bridge includes three viewing decks, two of which are covered with shed roofs. The foot bridge is divided into 16 segments. Each segment is 15 m long with a width of 2.2 meters. The ground plan dimensions of the viewing decks are approximately 15x7 and 15x11 m. As the main structural material has been chosen glued laminated timber of the strength class GL28h, other elements are made of solid timber of the strength class C24. The thesis includes an introductory document, options analysis, technical report, static analysis, bill of material and drawings.

The timber viewtower
Lecián, Martin ; Straka,, Bohumil (referee) ; Buchta, Stanislav (advisor)
The master's thesis deals with design and static assessment of loadbearing structure the timber viewtower on the hill Hostyn. The shape of the structure is very close oblate spheroid. Towers plan shape is a regular octagon whose outer diameter varies along the height. Tower in the footing and in the top measure 10,5 meters, at mid-height measure 6.5 meters. The height of the viewtower is 35 meters and view floor is located at a height of 30.5 meters. The main structure of tower consists outer towers curved wooden columns and interior steel column. Columns support the horizontal beams and bracing provide rigidity of the structure. The roof has a pyramid shape towers and tends to 17 °. Outer columns are designed from glued laminated wood GL24h, others carrying wooden beam are designed from solid timber C24 steel rods are designed from steel S235. Connections are solved using steel components. The work includes structural calculation, technical report and drawings.

Timber structure of a foot bridge
Kamrádová, Michaela ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
This Bachelor's thesis presents a proposal and a static assessment of a load bearing structure of a current footbridge which is also used for cycling. The footbridge is located near Frýdek-Místek. The length of the span is 17,5 meters, the width is 2,1 meters. The construction of the footbridge is solved as a space framework with intermediate bridge deck. The calculation is done using program Scia Engineer 14 and then revised manually. For the timber structure is used glued laminated timber GL32h and solid timber of the strength class C24. Basic wooden structure is designed in accordance with applicable standards for the design of timber structures.
