Prestressed road bridge in Staré Město
Krč, Rostislav ; Trenz, Jan (referee) ; Koláček, Jan (advisor)
The thesis focuses on design of superstructure of concrete bridge, which passes a roadway across the river Krupa in the town of Stare Mesto. It is a simple span structure with length of 19 meters. For further elaboration, post-tensioned concrete slab with trapezoidal-shaped cross section was chosen. Assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Furthermore, a design of post-tension according to former Czech technical standards (CSN) was studied. The thesis includes technical drawings and visualization.

Technical condition of sewer pipes
Došek, Jan ; Raclavský, Jaroslav (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor thesis is to define damages of sewer pipes from the constructional point of view and by selected damages set the limits according to valid standards in the Czech Republic. The beginning of this work is an introduction to the legislative and setting of the basic concepts. Another point of this part is to characterize particular materials and damages by which are they effected. It is the questions of ovalisation, longitudinal bending, positional deviation, mechanical wear, corrosion, crack, pipe break and collapse. The main point of this work are calculation part, where the limits for selected damages of particular materials are set one by one. The result are the summary tables that shows the limits and allow the comparison of these analysed sewer pipe materials.

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.

Design of simple engineering structure
Macková, Lucie ; Navrátil,, Jaroslav (referee) ; Klusáček, Ladislav (advisor)
Bachelor’s thesis processes methodology of calculating the deflection according to norm EN 1992-1. First of all it deals with the theory necessary to understand the whole process and explanation of each step. Next learned lessons are applied in the model calculation of deflections, which is performed at 3 beam elements of different construction heights. The resulting values are compared to point out changes in the final deflection according to different dimensions of the structure.

The Roofing of Terraces of a Stadium
Bartoň, Radek ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
My task was to propose and consider steel structure of roofing of a terraces on an athletic stadium. Terraces, with the ground-plan dimensions 12,0 x 80,0 m, are designed as a reinforced concrete structure and its structural analysis is not included in this thesis. Construction is situated in area of Rožnov pod Radhoštěm, which meant, It had to be accounted with considerable variable loads (wind, snow), which is associated with enlargement of a cross-sections. 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.

Breathing-induced fatigue in thin-walled steel bridge construction
Škaloud, Miroslav ; Zörnerová, Marie ; Urushadze, Shota
Several years ago, the authors started an experimental investigation into the breathing phenomenon of the webs of thin-walled steel girders , which to date comprised more than two hundred tests. The cumulative damage behaviour generated by web breathing was analysed, the process of the initiation and propagation of fatigue cracks induced thereby was studied, and their impact on the failure mechanism and the fatigue limit state of the girders was determined. And, to conclude, a recommendation for design, taking account of the aforesaid, was established.
