The roof structure of the multipurpose hall in Lipník
Gelová, Michaela ; Pilgr, Milan (referee) ; Šmak, Milan (advisor)
This bachelor´s thesis deals with a design of load-bearing roofing structure of the multipurpose hall in Lipnik in various material variants – wood, steel. The main truss /solid panel is a double-hinged / three-hinged arch with a span L = 25m and a height h = 12,5m. Arches are supported on the foundation by means of steel pivot joints. The connection between arches, are provided by the purlins, their length is 5m. A spatial rigidity of the structure is provided by the cross and longitudinal bracings.

Renovation of escalator
Kobzík, Martin ; Šebesta, Luděk (referee) ; Pokorný, Přemysl (advisor)
This master's thesis covers the construction analysis of an escalator by the Otis a.s. company and the conception of its modernization called "In-truss".This type of modernization consists in preserving the supporting construction of the 506-type escalator into which the components of newer 506-NCE series are to be built in. Such operation requires modifying the construction and creating adaptors used to anchor the new components to it. These modifications lead to the stress testing of the construction, that is done by using the finite elements method in NX-Ideas software. The thesis contains the design of selected subsystems of the escalator, the stress testing of the new supporting construction and the creation of volume model in CREO-Parametric application for further use.

Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.

Strength design and deformation analysis of the truss construction.
Ryšánek, Michal ; Nedělka, Pavel (referee) ; Vrbka, Jan (advisor)
This Bachelor thesis is focused on strength design and strain-stress analysis of truss construction. Simplified as a plain truss construction. One of the main goals of this thesis is calculate stresses for each member of the construction, depending on the load position. The cross section of beams were designed respecting safety conditions. The influence of the gravity field was not taken into account.

Strength design of the truss construction
Rašovská, Hana ; Horníková, Jana (referee) ; Vrbka, Jan (advisor)
Bachelor thesis deals with strength, stress and strain analysis of the plain truss construction. The aim of the thesis is calculation the size of forces for two storage of the system with resultant suggestion of the cross- section geometry. The different position of the load is also considered. Further the influence of gravitational field of the Earth is reviewed as well as displacements in characteristic places, in construction is defined.

Methods for reconstruction of the bar system
Kouřil, Jan ; Krpalek, David (referee) ; Florian, Zdeněk (advisor)
This work is focused on ways of reconstruction bar systems. The purpose of the study is to compare and evaluate the mobility and load change in the bars in case of change the bar structure. There are also carried out the methods for calculating the bar system. All reconstructions and calculations are performed on a simple truss bridge construction. ANSYS software was used to view the reconstructed deformation and loading system at the end of work.

Stress, strength and strain analysis of the crane truss construction.
Nedělka, Pavel ; Borák, Libor (referee) ; Vrbka, Jan (advisor)
This bachelor thesis deals with stress, strength and strain analysis of the plane crane truss construction. The aim of this work is the calculation of forces for the simple frame with the help of joint equilibrium equations. These forces will be modified by further construction treatment. This treatment turns the simply frame into the hyperstatic system. The obtained values data are the input data for the design of geometry of particular bars. The unknown dimensions will be determined by two strenght limit states. These limits are: limit state of elasticity and limit state of stability. Then we will make the strain analysis. It will determine the displacement in the action of the force, the effect of actual clearance as well as the brace failury effect to the construction safety. Further will be determined the influence of the weight of the construction to the strenght.

Multipurpose Sport Hall
Jakubíček, Tomáš ; Barnat, Jan (referee) ; Buchta, Stanislav (advisor)
I designed supporting structure of roofing for multipurpose sports hall located in Pardubice. Building height is 15 meters and the other two dimensions are 50x80 meters. It is an arched truss construction, which is located above the roof deck. The arch is asymmetrically supported with a height difference of supports 6.5 m. The actual frame is made out of steel S355 and is formed by circular profiles. The solution chosen offers free ceiling inside the hall and shows the supporting structures. Part of my bachelor thesis was to made static calculations and drawings.

Design of roof timber structure for the central station in Brno
Sikorová, Radka ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
This bachelor’s thesis deals with a design of loadbearing structure of roofing of the railway station in Brno. The main truss is a three-hinged arch which is maid of glued laminated timber with a span of 70,0m and a high of 11,7m. Arches are supported on the foundation by means of steel pivot joint. The conection between arches are provided by the purlins, their length is from 4,486m to 5,000m. The structure is horizontally curved by diameter R=600,0m, a length of centre-line is 445,5m. A spatial rigidity of the structure is provided by the cross and longitudinal bracings.
