Kamrádová, Michaela January 2018 (has links)
Topic of this Master's Thesis is a design and a statical evalution of a load bearing structure of an observation tower in Beskydy mountains. Ground plan of this structure is in a shape of a nonagon with a non-roofed interior space. Height of the observation tower is 38,5 m, the shape of a ground plan doesn't change with a radius of a circumscribed circle of 12 m. The structure is designed from glued laminated timber, solid wood and steel. Columns bear horizontal beams and their stiffness is ensured by horizontal and inclined reinforcing beams. Main load bearing columns, upper and lower beams are designed from glued laminated timber GL24h. Upper beams and beams of a gallery are designed from glued laminated timber GL36h. Horizontal stiffener is designed from solid wood C24. Central column, inclined beams, stairway, water slide cantilevers, rod and central rod are designed from steel of a strength class S235. Cantilever for gallery is designed from steel of a strength class S355. Connections are designed from steel elements. Statical evaluation, technical report and construction drawing are included

Most na silnici I/44 / Bridge on the I/44 road

Majer, David January 2018 (has links)
The subject of this thesis is the design and analysis of five-span bridge construction across the railway on the route Zábřeh - Šumperk and the Morava river. There will be made separated bridge for each direction, only right bridge is considered in the thesis. Object is located to 1st class road I/44 on the route between Mohelnice and Jeseník. Three variants were designed - two prestressed chamber girders, one prestressed chamber girder with prefabricated consoles and construction of concrete slab mixed with two steel girders. After these variants were weigh up and the first one, with the length of cantilevered construction 235,6 m and maximum lenght of span 60 m, was chosen for analysis. Calculation of load effects was made by software Scia Engineering 2013 and the analysis was made according to current standards by manual calculation depending on limit states and their influence on the design as well. Drawing documentation and visualization are also part of the thesis.

Statické řešení dostavby nemocnice v Písku / Static solution of hospital completion in Pisek

Kukla, Radim January 2017 (has links)
In this diploma thesis „Static solution of hospital completion in Pisek“ I study statical solution of one new building of hospital. Statical solution includes the design and dimensioning of reinforced concrete floor structures and peripheral beams. The floor structure consists of point supported reinforced concrete slab. The floor slab is supported by columns and walls. The aim of the project is to desing and evaluate the ultimate limit state of reinforced concrete slab and beams. Also was created 3D computational model to analysis the construction, model was created in software Scia Engineer. To verify the resulting values of internal forces was used to the method of replacement frames. The thesis includes an analysis of internal forces in the structure, while based on different types of soil. Individual values are compared. Finally was made drawings of solved part of the building.

Toleranzmanagement in der Produktentwicklung am Beispiel der Karosserie im Automobilbau: Toleranzmanagement in der Produktentwicklung am Beispiel der Karosserie im Automobilbau

Leuschel, Roland 28 June 2010 (has links)
Es wurde eine programmunterstützte Methode für die Umsetzung des Toleranzmanagements entwickelt, welche die Bereiche Entwicklung, Technologie und Qualität in gemeinsame Verantwortung bringt. Dabei galt es, den Iterationsprozess der Lösungsfindung in verschiedenen Detaillierungsstufen mit wenigen Schleifen und im Streben nach kurzen Entwicklungszeiten, geringen Toleranzkosten, Qualitätsverlusten und Blindleistungen zu durchlaufen. Ein stimmiges Toleranzkonzept überzeugt durch toleranzgerechte Aufbaufolgen, robuste und funktionsnahe Referenzierungen, kompensatorische Verfahren sowie toleranzunempfindliche Beeinträchtigungen und Auswirkungen. Die Auslegung aller toleranzrelevanten Produktanforderungen und Prozessgegebenheiten wird in Form von Toleranzketten und Maßkatalogen automatisiert dokumentiert und mündet schließlich in bestätigten Kunden-Lieferanten-Vereinbarungen.:1 Einleitung 2 Stand der Erkenntnisse 2.1 Grundlagen der Tolerierung 2.1.1 Anforderungen an Toleranzen 2.1.2 Tolerierung und Referenzierung 2.1.3 Modellierung von Abweichungen 2.1.4 Statistische Methoden und Kenngrößen 2.1.5 Toleranzkosten und Verlustfunktion 2.2 Toleranzmanagement 2.2.1 Teilgebiet des Qualitätsmanagements 2.2.2 Toleranzanalyse und -synthese 2.2.3 Erarbeitung des Toleranzkonzeptes 2.3 Produktgerechtes Toleranzmanagement 2.3.1 Produktqualität und Anforderungen 2.3.2 Modularität und Komplexität der Baugruppen 2.4 Entwicklungsintegriertes Toleranzmanagement 2.4.1 Phasen im Produktentstehungsprozess 2.4.2 Simultaneous Engineering 2.5 Fazit des Standes der Erkenntnisse 3 Toleranzmanagement im Automobilbau 3.1 Gliederung des Produkt- und Prozessmodells 3.2 Funktionsrelevante Anforderungen 3.2.1 Zielkatalog für die Außenhaut 3.2.2 Ermittlung der Akzeptanzgrenzen 3.3 Funktionsbeeinträchtigende Abweichungen 3.3.1 Abweichungen längs der Prozesskette 3.3.2 Abweichungen der Karosserie 3.3.3 Abweichungen der Anbauteile 3.3.4 Abweichungen in der Montage 3.3.5 Veränderungen vor Auslieferung 3.3.6 Veränderungen in der Nutzung 3.4 Potenziale für ein effektives Toleranzmanagement 4 Methoden des Toleranzmanagements 4.1 Der Problemlösungszyklus 4.2 Zielsetzung und Strukturierung 4.3 Funktionsbereiche und Qualitätsmerkmale 4.4 Baugruppen und Ausrichtkonzepte 4.5 Korrelation von Ursachen und Wirkungen 4.6 Toleranzketten und Produktstatus 4.7 Messpläne und Prozessstatus 4.8 Freigabe und Maßnahmen 4.9 Potenziale für ein effizientes Toleranzmanagement 5 Zielsetzung 6 Einsatz der Toleranz-Organisations-Matrix 6.1 Allgemeine Beschreibung 6.2 Bereiche und Detailierungsgrade 6.3 Bauteilkatalog und Zuständigkeiten 6.4 Konzepte und Anforderungen 6.5 Schnittlagenmodell und Referenzpunktsystem 6.6 Funktionsbeziehungen und Paarungselemente 6.7 Algorithmus der Toleranzanalyse und -synthese 6.8 Erzeugung von Maßkatalogen und Messplänen 6.9 Ermittlung der Abweichungen 6.10 Ergebnisse und Maßnahmen 6.11 Status und Historie 7 Nutzen der Toleranz-Organisations-Matrix 7.1 Gesamthaftes Toleranzmanagement 7.2 Effizientes Toleranzmanagement 7.3 Effektives Toleranzmanagement 7.4 Toleranzstrategien, -konzepte, -parameter 8 Entwicklungsintegriertes Toleranzmanagement 9 Kriterien für das Toleranzmanagement 10 Zusammenfassung und Ausblick

Vyhlídková věž v oblasti jihovýchodní Moravy / Timber structure of a view tower in southeast Moravia

Vrbka, Jan January 2014 (has links)
he master’s thesis consists of a case study of an observation tower design made of glue laminated timber and steel. There are two different tower shapes of anchored or free standing tower and these towers are compared. One of the design is chosen and elaborated into final detailing. A short review of main issues bound with the observation towers is given. The review deals mainly with loading (mainly priniples wind loads are analised) and evaluating of towers (ultimate limit states, service limit states and acceleration comfort). The height of final construction is up to 60m. The design is formed by a space lattice structure made of glue laminated timber and steel members of different class. The members are fastened mainly by means of dowel joints with slotted-in-plates . There is a light steel stairway inserted into the main structure.
