Prefabricated reinforced concrete hall with crane track
Velecký, Tomáš ; Kostiha, Vojtěch (referee) ; Požár, Michal (advisor)
This bachelor thesis is focused on static solution of prefabricated reinforced concrete hall with crane runway. Specifically, the cross-section of the hall, which consists of rectangular columns and a T-profile reinforced concrete truss, is solved here. The load on the structure is transmitted to the subsoil by calyx-reinforced concrete pavements. The bachelor thesis deals with the design and assessment of individual structural elements. Elements are dimensioned according to ČSN EN 1992-1-1: Design of concrete structures - general rules and rules for building structures. In the drawing part of the bachelor thesis are drawn drawings of the assembly of parts, shapes and reinforcement of individual parts.
Provozní degradace motocyklového oleje
Velecký, Tomáš
The diploma thesis is focused on description and detection of service degradation of motorcycle engine oil. The first part is an introduction to lubricants and their basic physical properties. Followed by an overview of the classification of motor oils according to their composition and viscosity. In other chapters the thesis deals with the issue of lubrication of internal combus-tion engines and motorcycle oil filtration. The first of 6 samples represents the new oil, other samples have been obtained from the tested motorcycle oil tank. The experimental part of the work examines the motorcycle engine oil. There is a description of the instruments by which the samples were collected in order to obtain different parameters of oil degradation. Density, viscosity and metals in oil were measured in all oil samples. The results of individual oil samples are shown in graphs. The rate of oil degradation was determined.
