<p>Detta examensarbete behandlar området stålfiberarmerad betongplatta. Istället för att använda en traditionellt armerad betongplatta undersöks möjligheten att använda sig av den alternativa tekniken stålfiberarmerad betong. Stålfiberarmerad betong består av vanlig betong med iblandning av stålfibrer vilket ger den unika egenskaper.</p><p>Rapporten utgörs av en jämförelse mellan en traditionellt armerad betongplatta gentemot en stålfiberarmerad betongplatta. I jämförelsen används ett referensobjekt som är den nya Konsumbutiken i Sunne där traditionell grundläggning med nätarmering använts. Detta alternativ jämförs med en teoretisk framtagen konstruktionslösning där fiberbetong används. Studien behandlar aspekterna dimensionering, genomförande, tid, ekonomi och arbetsmiljö. Målet med studien är att se vilket grundläggningsalternativ som hade varit mest fördelaktigt.</p><p>Resultatet som framkommit i denna studie visar att grundläggningsalternativet stålfiberarmerad platta på mark hade varit ett bättre alternativ i det givna fallet. Dimensioneringsmässigt leder den nya lösningen till en slankare konstruktion, enklare genomförande och bättre arbetsmiljö på grund av minskat armeringsarbete. Ekonomiskt blir det stålfiberarmerade alternativet billigare och även tidsbesparande.</p> / <p>This report manages the topic of steel fiber reinforced concrete slab. In this study we examine the possibility to use steel fiber reinforced concrete instead of traditional mesh reinforced concrete for the foundation. Steel fiber reinforced concrete consists of ordinary concrete mixed with steel fibers, which give it unique characteristics.</p><p>The report is based on a comparison between a traditional mesh reinforced concrete slab and a steel fiber reinforced concrete slab. A reference object has been selected for the study. The reference object is a new supermarket named Konsum in Sunne, Sweden, where traditional mesh reinforced concrete has been used for the foundation. This foundation is compared to a theoretically produced steel fiber reinforced concrete slab. The comparison is based on the following subjects: design, implementation, time, economy and working conditions. The purpose of this report is to determine which alternative is the most advantageous.</p><p>The result of this study shows that the steel fiber reinforced concrete alternative would have been a better solution for this foundation. The steel fiber reinforced alternative leads to a slimmer construction, easier implementation and better working conditions due to a smaller amount of reinforcing work. Financially, the steel fiber reinforced alternative is cheaper and leads to a shorter construction time.</p>

<p>The degree thesis is based on an architecture competition where the community had decided on producing residential buildings on the district <em>V</em><em>ä</em><em>stra kajen</em>. The community of Jönköping wanted to build two types of residents; one part was going to have residents with right of tenancy, were the company <em>V</em><em>ä</em><em>tterHem</em> is going to administrate. The other part of the residential was going to be tenant-ownership were the administrator is going to be <em>Riksbyggen</em>. The line of argument in the thesis is the design process of doing a proposal that would meet the requirements of the competition and of the companies'. Other requirements that also had to be considerate on the proposal were the adjustment with the existing environment and that it had to be appealable to society.</p><p>Question that assumes in the thesis and trying to be explained through the reading of the chapters is; "How the area is affected of the external conditions. How a residential yard and construction is going to be designed to get the best possible light- and view-alternative, and to get good internal planning. How the design is on the wining proposal. What are the energy requirement, and the other requirements; what kind of conditions does the area have".</p><p>Observation of the location has been carry out where analyzes has been made on wind-, sun-, vegetation-, traffic- and topographic conditions. Some researches has been done on the history of the city which is describe on this thesis and also different point of views of <em>Statsbyggnadvisionen</em>[1] has been explained; which also includes <em>Ramprogrammet</em>¹.</p><p> </p><p>Similar projects have been analyzed to get a bigger perspective on good internal planning and good resolutions on residential buildings with similar conditions. These analyzes have been used and reflected on the design of the project on <em>Västra kajen</em>, which is describe on following chapters. The reference projects have been chosen from three levels which the writers of this thesis choose to name; the community level, the national level and the international level. The objects are <em>Östra kajen</em> in Jönköping, <em>Henriksdalshamnen</em> in the <em>area Hammarbysjöstad</em> in Stockholm and the living area <em>Fyrholm</em> in Kobenhaven, Denmark. The analyses can be found in chapter 4.4.</p><p>After the analyzing phase a proposal on the living space on <em>Västra kajen</em> is designed, this design proposal is illustrated in chapter 4.5, where volume, internal planning, the residential yard and material etc is presented. During the whole design process there was a contact with the company <em>Riksbyggen</em> and Invar Selse that was the functionary of the competition, which also is presented in the chapter. The end of the thesis is base on a description of the winning proposal, where a comparison between the proposal of this thesis and the winning one is done.</p><p> </p><p>[1] Is a document from the community of Jönköping that describe the city planning and future vision of the city</p> / Formgivartävling
