Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

Is procuring qualified human capital from China a future for Sweden's wealth sustainability?

Our purpose was to examine why and how to start a ?bridge building enterprise? between qualified Chinese human capital and Swedish structure capital. The theoretical framework consists of literature from well renowned authors and is divided into four different parts: Intellectual Capital, Knowledge Management, China & Intercultural understanding. The empirical foundation has been gathered from a great variety of different sources in an attempt to cover the many complex angels in which this subject can be looked upon. Chinese students, managers in international companies with experience from China, Chinese employees in Swedish companies and different people with good knowledge of different areas of China are all among our respondents.In our conclusion we have reached the three following conclusions for why one should start a ?bridge building? enterprise in between qualified Chinese human capital and Swedish structure capital:-To fill future shortage of qualified human capital in Sweden.-To improve communication between Swedish companies and the Chinese market.-To develop qualified Chinese human capital with western standards..

Hästar i skrämmande situationer : en jämförelse mellan hanterad respektive fri habituering

In connection with riding and handling of horses, many accidents that can cause severe injuries to both horses and humans are existent. The cause is in most cases that the horse is frightened. The horse's fear also affects its usefulness and it has been shown to have adverse effects on the horse's welfare. To increase safety and improve the welfare of both humans and horses, it is important to find appropriate training methods to reduce the fear of horses in frightening situations. This experimental study compares handled habituation to free habituation.

Teamwork och det nya ledarskapet - en begreppsanalogi

The purpose of this essay is to further the understanding of contemporary management theory by conducting an analogy-study of the source to many of the terms today used in knowledge-intensive companies. The way a football club deals with knowledge work differs from how a conventional company deals with it. However, many of the terms, such as teamwork and coaching, are shared by the two types of organization. By using the analogy-method we hope to create a wider understanding for the shared concepts. We have used a hermeneutic perspective throughout the essay, which first and foremost means that we focus on understanding and explaining social phenomenons.

PWM Effekt Audioförstärkare

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

Ett omöjligt uppdrag? : - Det nationella provets skrivdel i svenska

Uppsatsens syfte är att redogöra för forskningens syn på det nationella skrivprovet inom ämnet svenska. Utifrån ett psykometriskt perspektiv, med inriktning på konstrukt, bedömning och användning, belyser uppsatsen potentiella problembilder med standardiserade prov inom en svensk, norsk och amerikansk kontext. Provet innehar en normerande ställning inom svensk utbildning, där det agerar rättesnöre över vad som utgör goda och mindre goda elevtexter. Forskningen visar också på den svårighet som existerar gällande provets interbedömarreliabilitet, där olika examinatorer bedömer proven olika. Vidare påverkar provet undervisningen, där dess genrepedagogiska utgångspunkt leder till en tanke om progression, där texttyper hierarkiseras.

3D-modellering av en plattrambro i Tekla Structures : Arbetsmetod av en fallstudie

Detta examensarbete ämnar besvara huruvida Tekla Structures kan fungera som ett lämpligt 3D-modelleringsprogram för konstruktionsgruppen Nyanläggning och Bro inom Grontmij Sverige. Med goda erfarenheter av Building Information Modeling, s.k. BIM, och 3D-modellering inom andra delar av Grontmij så fanns en önskan att optimera gruppens arbetsprocesser med den senaste kunskapen inom området. Arbetet har fokuserat på att praktiskt modellera en fallstudie baserat på ett av Grontmij tidigare genomfört anläggningsprojekt. För att säkerställa fallstudiens representativitet valdes en plattrambro med stor mängd armering som ansågs ha en komplex geometri vilket potentiellt skulle fördelaktigt kunna representeras i 3D.Vid skapandet av 3D-modellen och tillhörande ritningar delades processen in i tre steg; modellering, detaljering samt visualisering.

Husen under bron Förskola : Houses Under the Bridge Kindergarden

Kindergarden - How can we create different synergies between different fields that they can benefit from each other? What different activities will suit the kindergarden? How will our perception of the kindergarden, of its need and function in society, change?In this Degree Project in Architecture I will be investigating the combination of the kindergarden together with a restaurant and a dance studio. I believe these activities will harmonize since they have overlapping benefits: We all eat, move and grow.With the new architectural activities in mind, I will further investigate the importance of the kindergarden as a part of society, more specifically our perception of what function it may, may not or could fill. I share the idea with a lot of authors, scientist that we are headed toward a society where children are kept too safe, thus minimising their chance to experience and learn to cope with a harsh reality when they grow up as adults. It's ok to get hurt to an extent, as long as they do not endanger their lives..

Att effektivisera armeringsarbete : Från idé till genomförande

Most of today?s concrete structures that are built on site are mainly constructed in a traditional fashion with a lot of artisanal operations. One step towards industrializing the in-situ construction of concrete is to use prefabricated reinforcement. Through this method there can be a lot of savings when each bar doesn?t have to be placed and fixed separately on site.

Utmattning av vägbroar i armerad betong enligt eurokoder

Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.

Forskares roll i säkerhetisering - att bygga broar eller elfenbenstorn : En teoriutvecklande studie av Köpenhamnsskolans säkerhetiseringsteori med fokus på "bridging the gap" mellan forskare och policyskapare

Studien syftar till att undersöka forskares upprätthållande av säkerhetiseringen av Irans kärnkraftprogram och hur detta påverkar deras roll som potentiella policyskapare. Studien ämnar vara teoriutvecklande genom att definiera Köpenhamnsskolans aktörsroll inom säkerhetiseringsteorin på ett mer nyanserat och precist sätt. Studien går igenom olika perspektiv inom debatten kring ?bridging the gap? mellan teori och praktik och använder Köpenhamnsskolans säkerhetiseringsteori som analytiskt ramverk vid analysen av det empiriska materialet. Studien analyserar artiklar skrivna av amerikanska forskare i amerikanska tidskrifter och undersöker hur och om dessa upprätthåller säkerhetiseringen av Irans kärnkraftprogram.

Tonala skillnader mellan ett tryckande stall och ett limmat stall. : -hos en bouzouki

SummaryI have a great interest in bouzoukis and since I, during my education in guitar making, mainly have focused on building bouzoukis and other traditional folk instruments, I have chosen the bouzouki as the object of my degree project.In connection to the making of these instruments, I started to consider the construction of the bouzouki and why the bouzouki has such a characteristic sound.One of my theories is based on the fact that most bouzoukis are made with floating bridges instead of glued pinbridges. Do these types of bridges differ from each other tonally and if so, how much and in what way?To receive answers to my questions, I have built two identical bouzoukis with different types of bridges, one with a glued pinbridge and one with a floating bridge. I have been very precise in the making of these instruments, giving them the exact same dimensions and using material from the same piece of wood. This to make sure that the instruments should be as exactly alike as possible.After finishing the making of the bouzoukis, I arranged for a sound test where I let musicians play and listen to the instruments.

Biblioteksutvecklingen i Göteborgs södra skärgård, Styrsö folkbibliotek, 1943-1976

The purpose of this thesis is to describe and analyse the road towards a modern library in the southern archipelago of Gothenburg between the years 1943 and 1976. The archipelago consists of about thirty smaller and larger islands, of which seven are inhabited throughout the year. Styrsö and the surrounding islands composed a municipality of their own until 1973. In January 1974 it became a part of the municipality of Gothenburg, this is also the year when the only bridge in the archipelago was ready to be taken into use, between Donsö and Styrsö. There is no bridge between the mainland and the islands.

Is insourcing qualified human capital from China a future for Sweden?s wealth sustainability?

The Methodology used to gather empirical materials for this thesis has been different types of interviews. The interviews have been mainly unstructured personal interviews directly with our respondents, due to limiting factors some of the interviews have been carried out via phone or email.The theoretical framework consists of literature from well-recognised authors and is divided into four different parts: Insourcing & Outsourcing, Intellectual Capital, Knowledge Management, China & Intercultural understanding. The empirical foundation has been gathered from a great variety of different sources in an attempt to cover the many complex angels in which this subject can be looked upon. Chinese students, managers in international companies with experience from China, Chinese employees in Swedish companies and different people with good knowledge of different areas of China are all among our respondents.In our conclusion we have reached the three following conclusions for why one should start a ?bridge building? enterprise in between qualified Chinese human capital and Swedish structure capital: 1.

Numerisk simulering av jordtryck mot rörbro ? Med tillämpning av programmet PLAXIS

This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.
