Load-carrying structure of the covered footbridge between buildings in schooling premises
Fiedlerová, Lucie ; Karmazínová,, Marcela (referee) ; Melcher, Jindřich (advisor)
The subject of this master’s thesis is to design the supporting steel structure covered pedestrian bridge between the learning area buildings A and D of the Faculty of Civil Engineering, street Veveří 95 in Brno. The construction is designed as a bridge rod spatial structure with two main girders. The girders are a combination Vierendeel girder and truss structure. The girders are connected at the level of the upper and lower band by a crosspiece. The horizontal stiffness of the upper and lower surface structure is ensured by bracing. The upper surface of the pedestrian bridge is horizontal in the longitudinal direction. The lower surface of the pedestrian bridge is curved in order to overcome the difference in height between buildings A and D. This solution is the result of comparison an evaluation of three alternative solutions.

Crane Hook Block - Lifting Capacity 16 tons
Straka, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this thesis is the design of crane hook block with a capacity of 16 tons. Pulley block used for lifting and moving loads in a medium heavy-duty use. It is equipped with a simple hook. The work, therefore, the proposal contains solutions rope transfer, strength and dimensional calculations of components and assembly drawings, axes, pulleys and nut hook.

Crane hook block - lifting capacity 25 tons
Šanca, Kristián ; Trčka, Tomáš (referee) ; Malášek, Jiří (advisor)
The crane block is the lower part of the hoist. It is designed to fulfill a load capacity of 25,000 kg, while being safe and as light as possible. The work describes the principle of the hoist. A design solution is chosen in which two ropes are wound on a drum. The calculation of the hoist is in the calculation part, the components of the hoist are further described and calculated, using basic strength calculations. Attached is a drawing of the assembly and important details.

The Footbridge for Pedestrians across the Berounka River
Kováčová, Kristýna ; Buchta, Stanislav (referee) ; Šmak, Milan (advisor)
The aim of the Bachelor´s thesis is a static design of the footbridge for pedestrians across the Berounka river. The structure is created as three-dimensional model. The internal forces are calculated by FEM programme Scia Engineer 15.1. The load-bearing elements are designed with these forces. The length of the footbridge is 12,12 m, width 2,9 m and height 1,5 m. The footbridge is mostly made of glued laminated timber. Others materials are steel and timber. The steel is used fort connectors, wind bracing elements and bracing semi-frames. The construction is solved as timber beam with through-spain. The footbridge consists of two timber beams, floor beams, stringers and wind bracing elements.

Single-spar Travelling Crane MV 6,3/9
Čížek, Ondřej ; Pokorný, Přemysl (referee) ; Mynář, Břetislav (advisor)
Bachelor’s thesis will deal with single-spar travelling crane with under crane trolley, lifting capacity 6,3t. Aimed at design main structural parts, which I split to three main parts. First part will deal with design crane bridge, second part will design crosspiece and third part will design screw connection. In calculations and designs I keep to the ČSN standards and crane design literature. This Bachelor’s thesis was written by cooperation with Iteco company.

Bridge crane one-girder
Stanec, Stanislav ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with constructional design and a calculation of one-girder bridge crane with the requested primary parametres: lifting capacity 10 000 kg, span 12 000 mm, wheel base 2 500 mm, travel height 7 000 mm. In diploma thesis, there is executed analysis of constructional designs of box girders, drawn up technical report with the analysis of the choice of the construction with important technical and physical calculations. Calculations were executed according to valid Czech state norms and literature. Drawing documentation is enclosed to this thesis.

The footbridge for pedestrians and cyclists
Pupík, Antonín ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
This thesis deals with the design and assessment of footbridge for pedestrians and cyclists in the city of Hranice, Rybare district. The footbridge will serve as a crossing point over the river Bečva and will conect cycling trail with the street Rybarska. The content of this paper is to propose two different variants of structures. One of these options is selected based on their economic evaluation and further processed. Length of the bridge is 50m.

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.
