Ett undersöknings- och utvecklingsarbete för att lösa ett problem med att dränkbara pumpar i ett vattenavrinningssystem gick sönder med perioder på två år i genomsnitt, utfördes i samarbete med Cementa AB i Skövde. Orsak till pumpars haveri söktes och fanns vara bristande rutiner och kunskap om det underhåll pumparna krävde. För att lösa detta problem utvecklades riktlinjer för nyinköp av torruppställda pumpar för att möjliggöra kontinuerligt underhåll. Då möjligheter för placering av torruppställd pump saknades utvecklades ett pumpfundament för placering av torruppställd pump. Krav för utvecklingsarbetet togs fram i samarbete med Cementas underhållsavdelning och teoretisk dimensionering av dränkbara länspumpars dåvarande volymflödeskapacitet utfördes. Krav utvärderades och viktades med hjälp av parvis jämförelse. Dimensionering och kontroll av hållfasthet för utvecklat pumpfundamentet utfördes med hjälp av Finita Element Analyser i programvaran Pro/Engineer Creo 1.0 Mechanica. Kontroll av hållfasthet i infästning av pumpfundamentet samt svetsfogar utfördes analytiskt. Arbetet resulterade i en rekommendation till Cementa AB i Skövde att ta in offerter på nya torruppställda pumpar med hjälp av utvecklade riktlinjer och att tillverka det pumpfundament som tagits fram inom ramen för examensarbetet, för att placera nya pumpar på. Att noggrant följa de underhållsinstruktioner som pumpar har och att underlätta för personal att utföra detta underhåll ansågs kunna bidra till att pumpar skulle få en längre och mer ekonomisk livslängd. / A development project to solve problems with why submersible pumps in a run-off system broke down with periods of two years, on average, was performed in collaboration with Cementa AB in Skövde. Reason for the pumps breakdowns was searched and found to be inadequate procedures and missing knowledge of the maintenance required on the pumps. To solve this problem, guidelines for the purchase of new dry pit pumps were developed to allow for continuous maintenance. As the possibilities of placing a dry well pump did not exist at Cementa, a pump foundation was developed. Requirements for the development work were produced in cooperation with Cementas maintenance department and theoretical dimensioning of the submersible bilge pumps volume flow capacity was performed. Requirements were evaluated and weighted using Pairwise comparison. The design and control of the strength of the developed pump foundation was performed using finite element analysis in the software Pro/Engineer Creo 1.0 Mechanica. Controls of the strength of the attachment of the pump foundation and welds were performed analytically. The work resulted in a recommendation to Cementa AB in Skövde to bring in quotes on the new dry-pit pumps using the developed guidelines and to manufacture the pump foundation developed within the framework of the thesis. Cementa was also recommended to carefully follow the maintenance instructions for pumps and make it easier for staff to perform this maintenance. This was recommended to ensure that new pumps would have a longer and more economical lifetime.

The aim of the diploma thesis is the design of a continuous bridge construction of five fields in the direction of the town Albrechtice - Opava. The bridge overcame local roads and railway tracks and is part of the bypass of Albrechtice. From the three proposed variants, a pre-stressed two-beam structure was selected for the detailed solution and it is assessed according to the limit states and includes the effects of gradual construction. Further detailed drawings are drawn up.

This thesis describes the design of a road bridge in Trutnov through local communication. It is designed prestressed dvoutrámová construction of two fields with twin inclined struts. It developed a detailed static analysis and the bridge is considered to I. and II. limit state according to European standards - Eurocode. It is prepared detailed drawings.

The aim of diploma thesis is to design monolithic reinforced concrete underground structure, which is partly under existing building and partly will form the basis of a new outbuilding. Structure is designed as white tub, whitout any additional isolations against water a ground humidity. All structure elements (slabs, walls, beams) was designed according to standard ČSN EN 1992-1-1 for ultimate and serviceability limit state. Structural analysis was performed using Scia Engineer 2013 – Student version. The results were validated by simplyfied manual method.

This master’s thesis deals with ultra lightweight structural design concept of a lunar habitat. The beginning of the thesis is focused on basic properties of the Moon and different concept designs of lunar habitats and bases. Afterwards the main concept is introduced with defined loads followed by application of loads on the construction and design of main parts of the construction, especially design of an inflatable beam. Thesis is ended by manufacturing technology of an inflatable beam and design concept of main structural nodes.

This final thesis deals with new design of post-tensioned concrete bridge across river Vsetínská Bečva in the area Ústí u Vsetína. The existing bridge with three spans found in therms of inundation, that´s why is replaced by new four spans bridge construction. The bridge is situated on highway I/57 and used to transfer across the river. The superstructure is designed in three alternatives. Detailed assessment is only for one chosen variant a post-tensioned two-beam concrete.

The aim of the diploma thesis is the proposal of a bridge structure in the direction of Frýdek-Místek - Mosty u Jablunkova. A bridge is used to overcome the local road and Malý javorový stream. From three alternatives is selected a post-tensioned two-beam concrete struction and assessed according to the limit states. It is developed clear and detail drawings and visualization of the bridge.

The diploma thesis deals with the design of a continuous prestressed bridge structure transferring the D56 motorway on the Frýdek-Místek bypass. The bridge bridges the local watercourse of the river Olešná, Příborská street and road II / 473. Three studies were proposed, from which a variant of a two-beam continuous prestressed monolithic slab was selected and elaborated. The static model and calculation of its internal forces took place in the program SCIA Engineer 20.0. The calculation is performed according to valid standards, limit states, which also includes the effects of construction. The work also contains detailed drawing documentation.

This diploma thesis deals with the design of the bridge o the road I/58 over a watercourse and dirt road. The main content is the design and calculation of a continuous bridge structure with two bays. During designing the bridge, I based on Czech and European standards especially ČSN EN 1991 and ČSN EN 1992. A two-beam structure was selected from the developed three variants of bridging. Drawing documentation, construction procedure, visualization and static calculation were prepared for it. The result is an economical bridge structure with high durability and almost maintenance-free operation.
