Outdoor crane runway
Klíč, Radim ; Balázs, Ivan (referee) ; Pešek, Ondřej (advisor)
The aim of my bachelor´s thesis is a design and an assessment of a steel construction of an outdoor crane runway. The crane runway is used for operations of two bridge cranes. Each bridge crane has 40 tons of lifting capacity. The construction of the crane runway is located in a site of a factory for prefabricated concrete elements. The length of the track is 100 meters and the span of the crane bridge is 25 meters. The upper surface of cantilever is 10 meters above ground. A central beam of the crane runway consists of an uniaxially symmetrical welded I profile which is made from steel of the grade S355. Every single bar of a horizontal bracing beam is made from steel of the grade S235. Columns are designed as solid-web welded I profiles and they are made from steel of the grade S235. These columns are transversely fixed. Spatial rigidity in the longitudinal direction of the construction is provided by braking bracings. These bracings are designed as simple cross layout.

Footbridge across river
Klíč, Radim ; Pešek, Ondřej (referee) ; Balázs, Ivan (advisor)
The diploma thesis deals with a design of a steel loadbearing structure of a footbridge over a river. The footbridge is located in Svitavy and is designed for span length of 60 meters. The construction is preliminarily designed in two variants. A part of the thesis is also a comparison of both variants. The chosen variant has been elaborated in detail. It is an arched construction with a semi-through bridge deck. The main loadbearing structure consists of a pair of arches that support the steel-concrete bridge deck by means of rods in tension. The main loadbearing arches are inclined from the vertical plane towards the bridge axis and are fixed at the ends. All steel parts are designed from S355 steel, except for the rods that are designed from S460 steel. The bridge deck is designed from C 35/45 concrete. The spatial rigidity of the structure in the transverse direction is achieved by means of arc sway bracings.

Porovnání a optimalizace systému kontrol stromů na příkladu města Svitavy
Klíč, Radim
This bachelor thesis describes and evaluates systems of tree inspections in various municipalities in the Czech Republic. In the first section of this thesis there are some solutions defined for conducting tree inspections in municipalities in the Czech Republic and foreign countries. In the second section there is some characterization of management of green vegetation system in municipalities which were surveyed within this research and moreover there is some characterization of management of evaluation systems and tree inspection systems in these municipalities. In the third section there are some procedures defined which are used in the Czech Republic during the evaluation and the tree inspections and also some methods used in the process of creation of these activities. Extracted information is compared and analysed. Synthesis is used for a suggestion of an optimal solution for the regular tree inspections in Svitavy town.
