Detta arbete grundar sig på en befintlig ritning projekterad av Arkinova Arkitekter och uppfyller normal tillgänglighetsnivå. Ritningen består av ett lägenhetsplan med fem lägenheter vilka har en boarea mellan 36-64 m2. I detta arbete omprojekterades dessa lägenheter till höjd tillgänglighetsnivå enligt SS med avsikt att förbättra tillgängligheten för funktionshindrade grupper. Omprojekteringen utfördes med hjälp av BIM-programmet Revit Architecture 2013 med utgångspunkt från standarderna,           SS 91 42 21:2006 samt SS 91 42 22:2006, vilka utgör underlag för projektering av bostäder.       Syftet med denna studie var att utreda de merkostnader som är förknippade med en tillgänglighetsökning, dessa merkostnader beräknades i kalkylprogrammet BidCon. Resultatet visade att för att uppfylla SS rekommendationer kring ökad tillgänglighet, var en ökning av bruttoarean med 84 m2 i den ursprungliga ritningen oundviklig. Detta innebar en total ökning av bruttoarean med 25 %, vilket resulterade i merkostnader som uppgick till  126 014 SEK för lägenhetsplanet i höjd nivå. Dessa merkostnader inkluderar materialet i väggar, dörrar samt golvbjälklaget. Den procentuella kostnadsökningen för materialet blev således 22 %. / This work is based on an existing drawing designed by Arkinova Arkitekter, and is adapted to normal level of accessibility. The drawing consists of five apartments, with each apartment covering a total floor area between 36-64 m2. To improve accessibility for disabled groups, the apartments have been re-designed to a higher level of accessibility using BIM software Revit Architecture based on SS (Swedish Standard) 91 42 21:2006 and 91 42 22:2006. The purpose of this study was to investigate the additional costs associated with an increased accessibility; these additional costs were calculated in the spreadsheet program BidCon. The result showed that in order to comply with SS’ recommendation around increased accessibility, the floor area in the original drawing had to be increased by 84 m2 to allow increased mobility. This corresponds to a total increase of 25 %, which resulted in an additional costs of 126 014 SEK (22 % increase) including material for walls, doors and floor slab.

En svensk standard, SS 812310­ – Dimensionering av fiberbetongkonstruktioner, har nyligen tagits fram som skall säkerhetsställa kvalitén och underlätta dimensioneringen av stålfiberbetongkonstruktioner. Tidigare har det inte funnits en dimensioneringsstandard som täcker in området stålfiberbetong. Det har varit upp till enskilda konstruktörer att dimensionera utifrån metoder angivna ur ”Svenska Betongföreningens rapport nr 13”. Materialdata har hämtats från stålfiberleverantörer eller balkprovning. Detta har ibland medfört felaktiga dimensioneringar och en osäkerhet till användandet av stålfiberbetong som material. Förhoppningen med den nyutkomna standarden är att den skall underlätta dimensioneringen av konstruktioner med stålfiberbetong och därigenom att materialet börjar användas i bredare utsträckning. Syftet med examensarbetet är att granska den nyutkomna standarden genom att applicera dess beräkningsmetoder på en konkret dimensioneringsuppgift. I examensarbetet har två olika fält av ett bostadsbjälklag, med olika randvillkor, undersökts. Dimensionering med hänsyn till moment- och tvärkraftskapacitet har utförts i brottgränstillstånd, och med hänsyn till sprickbredd och deformationer i bruksgränstillstånd. Dimensioneringen har utförts dels med enbart traditionell armering och dels i en kombination av traditionell armering och stålfibrer. Resultatet av arbetet visar att användandning av stålfibrer i kombination med armeringsjärn ger en betydande minskning av sprickbredden, deformationerna blir mindre och tvärkraftskapaciteten ökar. Vi kunde dra slutsatsen att det är bra att en svensk standard för stålfiberbetong har tagits fram så att konstruktionsföretag i Sverige har något att förhålla sig till. Den behöver dock förtydligas i vissa avseenden samt revideras där vi upptäckte några brister. / A Swedish standard, SS 812310 – Design of Fibre Concrete Structures, have recently been developed to ensure the quality and facilitate the design of steel fiber concrete. Previously, there was no design standard that covered the material steel fiber concrete. It was up to the individual engineer to design the constructions based methods from the Swedish report “Svenska Betongföreningens rapport nr 13”. Material data was gathered from the steel fibre suppliers or beam test. This sometimes led to incorrect designs and also an uncertainty to the use of steel fiber concrete as a material. The expectation with the newly published standard is to ease the process of designing the constructions of steel fiber concrete and thereby the material will be used in a wider extent. The purpose of this thesis is to examine the recently published standard by applying its calculation methods on a design task. In this thesis, two different slab panels of a residential floor, with different boundary conditions, was investigated. Design with respect to moment- and shear force capacity has been carried out in the ultimate limit state, and with respect to crack width and deflections at serviceability limit state. The dimensioning has been performed partly with only traditional reinforcement and partly with traditional reinforcement in combination (Svenska Betongföreningen, 2008) with steel fibers. The result of this thesis shows that the use of steel fibers combined with reinforcing bar provides a significant reduction in crack width, the deformations become smaller and the shear resistance increases. We could conclude that it is good that a Swedish standard for steel fiber concrete has been developed so that construction companies in Sweden have something to relate to. However, it needs to be clarified at some aspects and revised because of some deficiencies we discovered.

The recent period of intensified electricity price volatility has challenged both private households and businesses, resulting in companies transitioning their strategies to address the uncertainties that follow. No previous study has analysed how electricity price volatility affects Swedish industries’ returns and electricity usage. Therefore, this essay aims to fill this knowledge gap and capture the impact of electricity price volatility on two different industries, one more electricity-intensive industry and one less electricity-intensive industry. By applying a DCC-GARCH model, the study examines the impact on the returns and electricity usage of two industries to analyse if electricity price volatility has affected businesses in terms of returns and electricity consumption.  The first DCC model was run on weekly electricity spot price data from Nord Pool and data constructed through a proxy of each industry’s average return. The results show that there is almost zero conditional correlation over time, ranging from 0.03 to 0.045, between the electricity price and each industry’s returns. There are no short-run spillover effects from electricity price volatility on the on the industries’ average returns. On the other hand, there is a long term spillover effect from electricity prices to the more electricity-intensive industry and no long term spillover for the less electricity-intensive industry.  The second DCC-GARCH modell is applied on monthly electricity spot prices from Nord Pool and data of monthly electricity usage of each industry. The industries are sorted by Swedish Standard Industrial Classification (SNI). SNI 17 stands for manufacture of paper and paper products and SNI 24 stands for manufacture of basic metals. The results from this part indicates that the dynamic conditional correlation between electricity price and the electricity usage in the paper industry is close to zero which differ from the basic metal industry which is positive. Beyond the dynamic conditional correlation, we find a short-term spillover effect from electricity price volatility to electricity usage in the basic metal industry, which is absent in the paper industry. On the other hand, there is a long-term spillover effect from electricity price volatility to electricity usage in the paper industry, which is absent for the electricity usage in basic metal industry.  Overall, our study shows that the businesses in the return proxy have preformed relatively well despite an uncertain period of volatile electricity prices. Simultaneously we find that the results for the industries electricity usage differ between the chosen industries.
