Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3

The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.

Förslag till ombyggnation av klipp- och bockningsmaskin

This thesis work has been performed on request by SWT (Scandinavia WeldTech AB). SWT manufactures, develop and sell ready to assemble building systems for concrete rafter beam applications. The beams in this system consist of a u-beam that is welded to a flange. To be able to fill the beams with concrete there is holes in the beams top end. The holes are made in a ?punching machine?.  These holes are cut out and the remaining steel piece is bent down in the u-beam.

Marknadens reaktion på bolagskoden - Wall street walk eller Wall street talk?

Titel: Marknadens reaktion på bolagskoden ? Wall street walk eller Wall street talk?Framläggande: 31 maj 2006Ämne: Kandidatuppsats, Redovisning 10 pFörfattare: Björn Arvidsson & Per HultgrenHandledare: Carl-Michael Unger & Erling GreenNyckelord: Corporate governance,Aktieägare,Internkontroll,Svensk kod för bolagsstyrningSyfte: Syftet med denna uppsats är att ta reda på vilken vikt marknaden fäster vid Svensk kod för bolagsstyrning och hur den eventuellt reagerar gentemot bolag, som man inte anser följer koden på ett tillfredsställande sätt.Metod: Kvalitativ metod. Semistrukturerade intervjuer per telefon.Teoretiska perspektiv: Corporate governance med fokus på agentteorin och shareholder activism, Slutsatser: Marknaden fäster endast mindre vikt vid koden, bortsett från att man ser den som en kvalitetsstämpel. Man vill alltså enbart ha reda på om koden följs eller inte samt om förklaringen till eventuell avvikelse är godtagbar. Eventuella konsekvenser av att inte lämna en godtagbar förklaring är betingat av storleken på ägaren.

Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme

In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.

Ytterväggar : En jämförelse och livscykelskostnadsanalys

This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..

Projektering av ett småhus med fördjupning i uppvärmningssystem

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper

The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..

Laserprojektor

This report describes a thesis project on 15hp. The purpose of the thesis project is to build a laser projector that reacts on sound waves and thus get a laser beam to draw visualizations of sound waves on a wall. The idea was that the design would be independent and not have to be plugged into any audio equipment. This was achieved by absorbing sound waves into a microphone. Another factor was to get a ?do it yourself? -feeling of the design and therefore it was chosen to be constructed using for example, old hard-drives.The result was a relatively large and bulky designed laser projector that can draw sound waves on a wall..

Fältmätningar av limträbalkars elasticitetsmoduler : utvärdering av tre mätmetoder

This study investigates three different methods for evaluating MOE,Modulus of Elasticity, in field measurements. The purpose is toinvestigate the possibility to use dynamic measurement methods infield measurements that hitherto (2010) has been performed with staticmethods. The objects of investigation are 20 glulam beams. The firstfield measurement took place in november 2007 and applied a staticmethod based on the standard SS-EN 408. The second measurement,described in this study, took place during summer 2010, and appliedstatic as well as dynamic methods.The MOE of wood is affected by a range different factors.

En plats - En identitet

We live in a society where we are not bound to one place. We are encouraged to be mobile and constantly moving between different locations. The life in a convent is a contrast to this; nuns live at a specific place they are bounded to by vows and can not leave. The sisters in the convent of St. Birgitta, Pax Mariae have promised to stay at the same place and live by the rules of the convent.

Klättring i skolan : En studie om klättring som en del av den svenska idrottsundervisningen

AimThe aim of this essay is to investigate the possibility to exercise climbing within the framework of the physical education in the obligatory school. We investigated how physical education teachers think about exercising climbing in school and how the Swedish Climbing Association is working to reach out to schools.MethodA questionnaire was sent out to 81 schools (Idrottshögskolans partner schools) in suburban Stockholm, which corresponds to 10% of the total amount of schools in that area. A mail interview was also made with a representative for the Swedish Climbing Association who also represented a local climbing association, to collect information about how they worked with schools and youth.ResultsWe have not found anything in the steering documents against exercising climbing during physical education. There are obstacles for exercising climbing during physical education, a wall for climbing is very expensive and the schools have a lack of space for this wall. The results from the questionnaire showed that 76% of all the schools that did not have a wall for climbing wanted to have one.

Gallery Wall

För vissa är graffiti konst, för andra är det ett tecken på förlorad kontroll. För mig är det ett redskap för att mötas. Jag har delat in mitt examensarbete i två delar. Den första behandlar visionen jag baserat mitt arbete på. Den andra handlar om design och placering av de fysiska paviljongerna. I den första delen har jag utgått ifrån ett scenario där den fysiska arkitekturen återspeglas i ett virtuellt gallerisystem jag get namnet Gallery Wall. Denna del finns bara på idébasis men har varit utgångspunkt då jag formgivit mina paviljonger. Jag har skapat fem olika paviljongstyper som tillsammans på ett teoretiskt plan utgör en och samma virtuella huvudform.I, eller rättare sagt på, paviljongerna ges tillfälle för vem som helst att måla och presenteras sin gatukonst. Min förhoppning är att mina paviljongtyper skall inspirera andra att bygga egna varianter som alla är del av Gallery Wall.
