Analysis of a plan curved cable stayed and suspension footbridges
Koláček, Jan ; Stráský, Jiří (advisor)
The aim of the doctoral thesis focuses on the static and dynamic analysis of a plan curved cable stayed and suspension pedestrian bridges suspended on a single-side of their deck. The first part of this thesis deals with an analysis of the equilibrium in the transversal direction of a deck cross section suspended on a single-side. The section and its arrangement should be designed so that the torsion caused by the deck self-weight and dead load would be minimal. This theory was verified on a simple study of a single-sided suspended section with and without prestressing. Second part of the thesis deals with the design of a study of a plan curved cable stayed pedestrian bridge. The study describes in detail a finding of an initial state of the structure and the static and dynamic analysis performed by software ANSYS. The static analysis describes the response of the structure on the most frequent variable loads only, but not design of dimensioning according to the valid codes. The dynamic analysis verifies a predisposition of the structure to the vibrations and others harmful oscillation effects. The next objective of the thesis was to design a study of a plan curved suspension pedestrian bridge suspended on a single-side. A process of an analysis of these structures has not found in any available references. Especially, the finding of an initial state of a suspension cable has not been documented anywhere and by anybody. The study was analyzed with the same geometry as the cable stayed variation in order to compare both structures. The static and dynamic analysis was performed, too. The last part of the thesis describes the verification of structural solution on a fully functional model in a 1:10 scale, proposed process of the initial state finding, response of the structures on the loading and ultimate load test. The important step is the comparison of the results of the completed physical model and the calculation model.

Urban design of waterfront in Třebíč
Kadlecová, Sylva ; Ležatka,, Lukáš (referee) ; Pavlovský, Tomáš (advisor)
The thesis of my dissertation is an urban design of waterfront of Jihlava river in Třebíč, which runs through the center of the city and becomes its part. The inner city and the river basin are wedged into the valley, which is formed by a rocky terrain. The territory I am dealing with concerns several parts of Třebíč – Stařečka, the Inner Town, Zámostí and Podklášteří. This area is defined from the south by an arterial road and the bus station across the Suchniova street, and the main road on the Smila Osovského street. From the north, this area is lined by a rocky terrain, conservation area – the Jewish town which is registered on a UNESCO World Heritage List, under chateau meadow, continuing up to the summer swimming area Polanka. The outcome of this thesis is a total revitalization of described area and transformation of this town into an attractive Down structure that would offer a wide range of leisure activities, not only for people living in this territory but for tourists as well. The described territory is divided into several parts – the part in proximity to the outdoor swimming pool Polanka, then the part concerning the bus station and the right riverside. The main idea is to interconnect these parts and to komplete the urban structure following the original structure of the buildings. The new buildings would be mostly residential, with commercial and administrative areas on the first three floors. This administrative part also creates some sort of noise barrier from the arterial road. Clean areas intended for living are localized along the riverside in the western part of Stařečka. The flat orientation responds to the calm potential of Jihlava river, which creates a pleasant visual perception. Therefore, the quiet rooms are orientated to the north. Along the banks of the Jihlava river is proposed a quiet zone with both sport and recreational character, which helps changes of passive and active zones. In a close proximity of these
