Experimentální stanovení hydrodynamického zatížení modelu přelévané mostovky / Experimental determination of the hydrodynamic load of the flooded bridge model

Naiser, Dominik January 2020 (has links)
The diploma thesis deals with experimental determination of hydrodynamic load on the overflowed bridge deck model. In the first part of the thesis the author describes the analysis of the problem together with the basic physical laws and principles that are used or assumed in the measurement itself. In the second part the author describes the measurements in the laboratory of the Faculty of Civil Engineering and its gradual processing. At the end of the work are described the results of measurement, their comparison with numerical modeling, other authors and their possible use in practice.

Analýza dynamického chování štíhlé mostní konstrukce a návrh zařízení na omezení vibrací / The assessment slender bridge structure subjected to dynamic loads and design of the damping devices

Řehová, Jana January 2020 (has links)
This master thesis deals with the dynamic analysis of a footbridge. Computational model of the footbridge was created using ANSYS software. The model was subjected to dynamic wind load in longitudal and lateral direction. Furthermore pedestrian load in lateral direction was analyzed. Afterwards, due to unsatisfactory response to the pedestrian laod, a tuned mass damper was introduced to reduce the vibration. This lead to decrease in the vibration to a satisfactory levels, as is shown in the analyses of the model.

Průzkum a hodnocení železobetonové mostní konstrukce / Survey and assessment of reinforced concrete bridge construction

Šnédar, Jaroslav January 2020 (has links)
The aim of this thesis is to evaluate the real condition of reinforced concrete beam bridge located in Brno Jundrov. In order to evaluate this condition, there was made the main bridge inspection. Subsequently, a number of diagnostic methods were used, such as hardness tests, concrete stress strenght, ultrasonic pulse method, including their evaluation. In terms of the main inspection, the condition of construction of the bridge was evaluated as V - bad. We found out that the concrete from which the bridge is built of is in very good condition. The problem, however, is the condition of the reinforcement located on the bridge. Based on its condition there must be expected lifespan within the next 5-10 years.

Nové brněnské hlavní nádraží a jeho veřejná prostranství / Brno New Train Station and its Public Spaces

Nytrová, Bohdana January 2020 (has links)
For almost one hundred years, Brno has been deciding where the place of a new main train station should be. The works have almost started several times, but the various affairs have always postponed it. Two years ago, it was finally decided that „the River option“ would be constructed. So far, only the technological template has been written – e. g. railway bridge or platforms outline. The thesis focuses on the architectural design of the main building, the roof construction above the railways and spaces below the station bridge. In the design, the outlying urban structures are also dealt with. These include the locations of a bus station, taxi services and bike stands. Moreover, the design also mentions the station’s connection to the city networks. The main motive of the design is to put the main train station building into the centre of the city’s attractions – to make it visible. A boulevard’s view is oriented to the St. Peter’s cathedral – a famous Brno’s building. Just as the mentioned cathedral, the station is important for the city and deserves to be seen. A strong arched construction on four pillars serves as a roof over the railways and places where most visitors are expected to be most of the time. The arch also connects the public transport lines and the bus station. Part of a roof shaped like waves around the main hall connects the structure with the riverside nearby.

Předpjatý komorový most / Prestressed box girder bridge

Štíchová, Kateřina Unknown Date (has links)
The subject of this diploma thesis is the design of a load–bearing structure, whitch is situated in the extravillain between the town of Chomutov and the village Křimov. Main purpose of this structure is to pass a roadway I/7 across the valley. There are three options of design and one of them – the prestressed box girder bridge with slanted walls is chosen for more detailed elaboration. The major load–bearing structure is five–span with lenghts 46.50 + 58.00 + 58.00 + 58.00 + 46.50 m, made of post–tensioned nad cast–in–place concrete. The total lenght of load–bearing structure is 269.00 m and the width of load–bearing structure is 13.50 m, the bridge is straight in plan. The structure is analyzed by several computational models, which are designed in Scia Engineer 20.0 software. The structure is analysed in longitudinal and cross directions. The assessments of load state limit and usability limit state are made according to valid standards. This thesis also included time dependent analysis (TDA), that takes construction stage analysis into account.

Průzkum a hodnocení mostu na dálnici D2 / Survey and Assessment of highway D2 Bridge

Výpustek, Libor January 2013 (has links)
This thesis deals with the exploration and evaluation of the existing bridge carried him on the highway D2. The work is divided into theoretical and practical parts. The theoretical part focuses on the technical surveys, diagnosis of building structures and some methods of investigation and testing of building structures. In the practical part the visual inspection and diagnosis of disorders of the highway bridge substructures ev. No. D2-058, to determine material characteristics substructure and evaluate the state of the bridge. In conclusion, the practical part of the recommendations for the design and method of repairing the bridge.

Vybrané části stavebně technologického projektu realizace obloukového mostu / Selected Parts of the Construction Technology Project of Realization Arch Bridge

Gurgul, Roman January 2013 (has links)
Diploma thesis deals with constructive technological preparation of bridge structure SO-201. This 86m long bridge is located in a non-built-up area of the city of Nitra in Slovakia. Bridge structure is part of project Highway R1 Nitra, západ - Selenec. Bridge is formed by a self-anchored arch structure with intervening bridge deck.The bridge superstructure is formed by steel arches filled with concrete ,steel girders and beams locked with a reinforced concrete slab.

Návrh mostní konstrukce na rychlostní komunikaci / Design of the speed-way bridge structure

Nádvorník, Ondřej January 2013 (has links)
This Master's thesis deals with the detailed design of the supporting structure of the bridge with two sections, with the rise in the direction of the intermediate support, and cross-cut single-beam construction. The supporting structure is designed from the prestressed concrete, prestressing losses are accurately quantified. It also deals with the assessment of pillar base threshold and pilot groups. The assessment was carried out according to the limit states.
