Most komorového průřezu / Bridge formed by cell box girder

Zifčák, Karel January 2016 (has links)
The subject of this thesis is the design and assessment of the bridge construction across the deep valley on highway traffic. From three variants, which were compared to each other, was the most suitable further examined. The solved structure is made of post-tensioned concrete, and is formed with cell box girder with transverse overhangs, which are supported by prefabricated struts over the length of the bridge. The load was considered by the European Standard EN 1991-2 - Traffic loads on bridges and dimensioning according to EN 1992-2-Design of concrete structures - Concrete bridges - Design and detailing rules.

Příprava a organizace výstavby mostu na Silnici II/377 / Project planning and management of construction of the bridge on the road II / 377

Soukup, Ondřej January 2017 (has links)
The subject of this thesis the construction and technological preparation for the construction of the bridge ev.č. 377-007 across the Býkovka river in the municipality Rájec - Jestřebí, which is part of the reconstruction of a main road II / 377 Bořitov - Rájec. The thesis is elaborated a technical report on the structural and technological project, coordinating construction situation, the situation with wider relationships routes following the stages, time and financial plan – by objects, study the implementation of major technological stages of the building SO203 project site equipment, design of the main construction machines and mechanisms, the timetable of the main building structure, workers deployment plan, plan of machines usage, a plan for securing material resources for SO 203, technological regulation for the implementation of bored piles of, inspection and test plan for pilots, budget SO 203, sequence diagram construction, control and monitoring plan and calculation of bearing capacity of the bridge foundation piles.

Dálniční most přes široké údolí / Highway bridge over wide wally

Mertová, Eliška January 2017 (has links)
The aim of this diploma thesis was the design of three possible variants, how to span the wide and deep valley with a bridge. After an evaluation, situation of the highway on the only wide load-bearing structure which is constituted by a box girder with transverse cantilevers supported by prefabricated bar braces, was chosen as an optimal solving. The load- bearing structure made of post- tensioned concrete is going to be incrementally launched and be supported by one-column pillars along an axis of the motorway. The work is composed of a detailed design of this preferred variant, which is processed according to the ultimate and serviceability limit state including the construction stage analysis of the bridge by the construction technology by an incremental launching method.

Návrh trámového dálničního mostu / Design of highway bridge formed by beam girder

Řezníček, Martin January 2017 (has links)
The aim of diploma thesis is to design a made-up bridge construction over the road network.There were made three studies of bridging which were compared consequently. Two-joint ginder without haunched was selected as the most suitable option and it was designed in details. The construction was assessed according to the ultimate and serviceability limit state.

Lávka přes Labe / Footbridge across the Labe

Krč, Rostislav January 2017 (has links)
The thesis focuses on design of prestressed concrete footbridge which passes pedestrian and bicycle path over the Elbe river near city of Celakovice in the Czech Republic. Three different bridge options were analyzed and for further development a cable-stayed footbridge was chosen. Its bridge deck is formed of a box girder supported by cables in its vertical axis and all cable stays are anchored into two concrete A-shaped pylons. This structure was analyzed in SCIA Engineer and assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Both the global structural behavior and the local structural integrity of box cross-section were assessed as well as construction stages and cross-sections of pylons and cable stays. Assessments were performed in IDEA StatiCa combined with hand calculations. Eventually a dynamic response of structure was analyzed. Natural modes and frequencies were found and forced oscillation response was evaluated. The thesis includes technical drawings, construction process and visualization.

An SEM Study of Blastodinium Parasitism of Estuarine Calanoid Copepods: Impact on Mankind

Toma, Nicholas, Kunigelis, Stan C, PhD 07 April 2022 (has links)
Blastodinium, a genus of the phytoplanktonic dinoflagellates, was found to be inhabiting the gut region of the copepod species Labidocera. Copepods are ubiquitous in aquatic environments, being the most numerous multicellular organisms on planet earth. Being primary consumers, they play important ecological roles, passing energy from one trophic level to the next. As zooplankton, estuarine copepods contribute substantially to carbon cycling as they undergo diurnal migration to avoid daylight UV-B damage and surface water predation. Blastodinium are presumed to infect copepods via ingestion of zoospores by juvenile hosts, who function as microhabitats for acquiring nutrients in non-photosynthetic species or in nutrient-limited environments. Blastodinium may hinder reproduction of copepod hosts, thereby influencing local copepod populations and, by extension, food webs up to humanity. Copepod populations may also help contain disease spread, such as malaria and Dengue fever, through their consumption of mosquito larvae in standing water. Further evaluation of copepods for Blastodinium may help shed light on the limited knowledge of this species and the nature of its relationship with copepods, as well as its effects on copepod populations and the higher order consequences of its parasitism.

Lávka přes dálnici D1 v Bohumíně / Pedestrian bridge across the highway D1 in Bohumín

Muroň, Vlastimil January 2022 (has links)
The aim of final thesis is design and assessment of footbridge over highway D1 in Bohumín. The design is processed in two options. From these two options there is cable-stayed construction solved in greater detail. Because counstruction is in circular arch with small radius, it is necessary to contain real geometry to computational model. Model is created by beams and construction stages are included too. The construction is assessed for the ultimate and serviceability limit state according to valid standards. In the thesis is performed eigenvalue analysis and harmonic response of the construction. Detailed drawings are included too.

Dálniční most přes Trať SŽDC / Highway bridge across a railway

Mičánek, Ondřej Unknown Date (has links)
The topic of this thesis is design and evaluation of the bridge structure. Three variants of bridging were created, among which the variant with prestressed girder deck and seven spans was chosen to detail processing. The bridge construction is built on sliding steel girder in several stages. Construction is evaluated considering the ultimate serviceability state and ultimate limit state. Emphasis is also on evaluation of construction stages. The calculation of load effects and analysis of building in stages was done in Scia Engineer 19.1 software. Design and evaluation were done according to currently valid European standards.
