Full textThis project is grounded in a question about how a school building in itself can stimulate learning and curiousity. There are many ways of which this can be executed, but this project focuses on spatial design. Inspiration comes mostly from environmental design in games and from the architect Herman Hertzberger and his book "Space and Learning". The building consists of a program for middle school and junior high school, and is distributed in a way that makes orientation intentionally hard. The rooms are placed as cubes with massive or partly massive walls. They are connected by a glass facade, and the space between becomes place for interesting spatialities. Another method for creating stimulation and curiousity is sightlines. They are horizontal: in the shape of glass walls, and vertical: by openings in the floor structure. The idea is that the students, by exploring and getting to know their school, also learns to find not only their classrooms or lavatories, but also those nooks and crannies that is formed in the in between space. There becomes a contrast between the rooms: where the activities are ruled by teachers and the curriculum, and the in between spaces: where the activity is free and formed by the students themselves.

Full textAn elementary school for children aged 4 to 9 in the suburb Årsta in Stockholm. The school is located adjacent to a new residental area surrounding Årstafältet. The school will cater to around 500 students and a sport centre which will be available to the public. The program is divided into two volumes, where the sports centre is placed as the endpoint to an activitypath stretching across Årstafältet. The school is constructed with a wooden frame with adobe features, and interiorly exposed wood and earth. Three massive rammed earth walls mark the students abiding-places. Each class has its own abiding-place constituted by cloakroom, homeroom and a group activity room, which is intended to work as a safe base point throughout the school day. Workspaces and community spaces are designed to meet different preferences and social contexts. The shared workspaces consists of sociofugal spaces ment for separating the students from each other, while centered sociopatal spaces bring students together.

Full textThree projects; two housing projects in Stockholm (Marievik and Årsta) and a submarine museum in Karlskrona. The housing projects show two different ways of dealing with Stockholm suburban planning. The project in Marievik is located in a business area in Liljeholmen close to Hornstulls block city and has the Haussmann planning as model. Orthogonal streets and blocks are made the symbol of the functions of city life. The city council demanding a first floor in “stone”, being a constructive material long gone in these types of buildings. At the outskirts of the ABC-city is the Årsta project which neighbors five tall tower blocks in the north and lamellar in the south. In this project the open city planning is maintained and the house in is form and sitú is a mediator between the tower blocks and the lamellar. The submarine museum in Karlskrona is and addition to an existing Museum of marine warfare. The museum received one more submarine and the decision was to build a shell around them – in form relating to the more modern marine warfare technologies – stealth ships and bunkers.

Full textNätverksteamet på Enskede-Årsta stadsdelsförvaltning är ett öppenvårdsteam inom stadsdelen. Teamet är kopplat till barn-, ungdom- och familjegruppen och kan arbeta på uppdrag av antingen socialsekreterare eller utifrån att föräldrar själva kontaktar teamet för råd och stöd. Syftet med denna uppsats är att göra en brukarutvärdering av teamets arbete med samarbetssamtal mellan separerade föräldrar som är bosatta inom stadsdelen. Vi har använt oss av en kvantitativ metod där fjorton föräldrar telefonintervjuats utifrån en enkät med huvudsakligen standardiserade frågeställningar. Frågeställningarna i rapporten är: vilka är de föräldrar som kommer på samarbetssamtal till Nätverksteamet på Enskede-Årsta stadsdelsförvaltning? Hur upplever föräldrarna samtalsformen, samtalsledaren och reflektören? Finns det någon skillnad i upplevelse mellan mammor och pappor samt finns det några grupper eller kategorier som utmärker sig i undersökningen? Resultaten visar att föräldrarna i undersökningen är nöjda med de insatser som Nätverksteamet erbjuder. Vissa skillnader framträder dock mellan olika grupper, så som kvinnor-män och initiativtagare-icke initiativtagare. Till exempel är männen något mer positivt inställda till reflektören och de som inte varit initiativtagare till samtalen är lite mer negativa till det första samtalet. Reflektören som medverkar under samarbetssamtalen har av respondenterna blivit mer uppmärksammad, i både positiv och negativ bemärkelse, än samtalsledaren. De teoretiska utgångspunkterna har varit medlingsteori samt brukarorienterad utvärdering.

Full textArbetet i föreliggande avhandling omfattar analyser av befintliga bågbroar med ovanliggande fyllning. Huvudsyftet är att uppskatta bärförmågan i brottgränstillstånd. En fallstudie av gamla Årstabron redovisas, vilken utgör både initieringen och en direkt tillämpning av föreliggande forskning. Kravet från broförvaltaren är att öka brons livslängd med 50 år, samtidigt som axellasten ska ökas från nuvarande 22.5 ton till 25 ton. Utförda analyser visar på stor spridning i uppskattad bärförmåga, beroende på ett stort antal parametrar. En av de främsta faktorerna är fyllningens egenskaper, vilken kan resultera i en markant ökning av bärförmågan p.g.a. samverkan med bågen. Baserat på teoretiska analyser, tillståndsbedömningar och krav från broförvaltaren beslutades att bron skulle förstärkas. En förstärkningsmetod har utvecklats i nära samarbete med broförvaltaren och personer som tidigare utfört tillståndsbedömningarna. Analyserna visar ett utpräglat tredimensionellt beteende, vilket har föranlett användandet av icke-linjära finita elementmetoder. Krav på full trafik under samtliga förstärkningsarbeten har resulterat i att dessa utförs enligt en föreskriven ordning, som ska reducera minskning i bärförmåga under samtliga etapper. Förstärkningsförslaget godkändes av Banverket och är för närvarande under byggnation. Enligt plan ska dessa slutföras under 2012. Fältmätningar har använts för att bestämma det statiska verkningssättet under brukslaster, vilket visas ge goda resultat. Resulterande töjningar från passerande tåg har uppmäts i bågen, både före, under och efter förstärkning. Resultaten har använts både för att kalibrera beräkningsmodeller och att verifiera utförda förstärkningar. Samverkan mellan båge och fyllning har inte kunnat verifierats för den aktuella bron och de utvecklade förstärkningarna baseras på en modell där både fyllning och sidomurar endast utgör yttre verkande last. De framtagna finita element modellerna har jämförts med experimentella resultat från litteraturen, omfattande tegelvalvsbroar med ovanliggande fyllning belastade till brott. Generellt erhålls god överensstämmelse om full samverkan mellan båge och fyllning antas. Om fyllningen istället endast betraktas som yttre last, minskar lastkapaciteten ofta med en faktor 2 till 3. Fortfarande uppvisar ett antal faktorer stor inverkan på bärförmågan, vilka ofta är svåra att med säkerhet bestämma. Ett konservativt betraktningssätt rekommenderas, även om delvis samverkan med fyllningen fortfarande kan öka bärförmågan avsevärt.

Full textStructural Health Monitoring (SHM) is a helpful tool for engineers in order to control and verify the structural behaviour. SHM also guides the engineers and owners of structures in decision making concerning the maintenance, economy and safety of structures. Sweden has not a very sever tradition in monitoring, as countries with strong seismic and/or aerodynamic activities. Anyway, several large scale monitoring projects have taken place in recent years and SHM is slowly making entrance as an essential implement in managing structures by engineers as well as owners.
This licentiate thesis presents a state-of-the art-review of health monitoring activities and over sensory technologies for monitoring infrastructure constructions like bridges, dams, off-shore platforms, historical monuments etc. related to civil engineering. The fibre optic equipment is presented with special consideration.
The permanent monitoring system of the New Årsta Bridge consists of 40 fibre optic sensors, 20 strain transducers, 9 thermocouples, 6 accelerometers and one LVDT. The aims of the static study are: to control the maximal strains and stresses; to detect cracking in the structure; to report strain changes under construction, testing period and in the coming 10 years; and to compare conventional system with fibre optic system.
The system installation started in January 2003 and was completed October 2003. The measurements took place from the very beginning and are suppose to continue for at least 10 years of operation. At the construction phase the measurements were performed manually and later on automatically through broad band connection between the office and central data acquisition systems located inside the bridge.
The monitoring project of the New Årsta Railway Bridge is described from the construction phase to the testing phase of the finished bridge. Results of the recorded statistical data, crack detection and loading test are presented and a comparison between traditional techniques like strain transducers and fibre optic sensors is done.
Various subjects around monitoring and sensor technologies that were found under the project are brought up in order to give the reader a good understanding, as well of the topics, techniques and of the bridge. Example of few applications is given with the aim of a deeper insight into monitoring related issues.

Full textThe construction's construction is based on a few simple thoughts. One thing is that I did not want to break up the flows already in place. This I did by making "a hole" in the bulding at a place where a flow went by then the rest of the building was made to go along with the flows. The curved shape comes from my idea that it is easier to meet a soft shape and interact with it rather than a flat-shape that can be perceived as more avid. The part that was opened has on the floor that goes over the opening ad administration. This was to give it a form of actoriness, it stands out and goes over that road into the school area. This subtle gesture is to somehow create an actor of school and a form of order. The sports hall that is located in the built-up glimpses emerges a bit easily in the phase grains from the north northeast. It is buried under the school when the crowded sports arena built in Stockholm is already being built underground (some exceptions exist). It is dug down to save in place and cause it does not need or should have direct light emitting. The dining room comes from an idea that the design in the dining room must try to imitate a finders resturant. This is to raise the status of school food. It is a big part of how you are living your food depending on the environment in which you are living. The idea behind the building's execution is simple. I did not want to break up the flows that were already in place. By making holes in the building, an already existing flow could be utilized in order to gain more life and strengthen the flows in the rest of the building. The curved shape comes from the assumption that it is more pleasant to meet and interact with a soft shape is with a flat shape, which is more perceived as more rejection. The administration houses the part of the floor that goes over the opening, to give a sense of authority. The idea is that by placing the administration in the part that crosses the road into the school area, the authority is maintained and contributes to order and calm. The sports hall is hidden and only appears in the facade seen from the north-northeast. It is buried under the school. This to save space and because the activities in the building do not require direct light emitting. The same practice is being used today for the construction of most new gymnasiums in Stockholm. The dining room design is made to create the feel of a finer restaurant. This is to raise the status of school food. It is obvious that the experience of a meal differs depending on the environment in which you are located.

Full textA new district is planned at Årstafältet, with a public urban activity path. We want to give our school a special position in this newly built context. Årstafältet is a large-scale horizontal location, and therefore requires a larger gesture - something that stands out and breaks the horizontal field. To work at height therefore felt obvious for us and verticality became an important word in our work.The building also meets the landscape by being an extension and an end to the activity path. Urban life and street activity continues into the building, making the building a node and a landmark on the site. The fact that the building extends upwards also means that a large area on the site is released, therefore a piece of Årstafältet is kept.The given program for the new school building has the title "Sport and school". We have chosen to interpret the word sport as activity and movement, and this we have linked to the vertical grip of the building. The activity theme frames the entire building by the fact that an athletic hall is located at the bottom and one at the top. Between these sports halls, different types of vertical communications span, which also begin and end in two stands.The program also expresses the wish that the building should be more than just a school - there should be room for public functions. Therefore, the building's rooms are designed and intended to be used in a multifunctional manner.

Full textToday’s bridge design work in many cases demands a trustworthy dynamic analysis instead of using the traditional dynamic amplification factors. In this thesis a reliable 3D Bernoulli-Euler beam finite element model of the New Årsta Railway Bridge was prepared for thorough dynamic analysis using in situ bridge monitoring for correlation. The bridge is of the concrete box girder type with a heavily reinforced and prestressed bridge deck. The monitoring system was designed for long term monitoring with strain transducers embedded in the concrete and accelerometers mounted inside the edge beams and at the lower edge of the track slab.
The global finite element model used the exact bridge geometry but was simplified regarding prestressing cables and the two railway tracks. The prestressing cables and the tracks were consequently not included and an equivalent pure concrete model was identified.
A static macadam train load was eccentrically placed on one of the bridge’s two tracks. By using Vlasov’s torsional theory and thereby including constrained warping a realistic modulus of elasticity for the concrete without prestressing cables and stiffness contribution from the railway tracks was found. This was allowed by comparing measured strain from strain transducers with the linear elastic finite element model’s axial stresses. Mainly three monitoring bridge sections were used, each of which was modelled with plane strain finite elements subjected to sectional forces/moments from a static macadam train load and a separately calculated torsional curvature.
From the identified modulus of elasticity the global finite element model was updated for Poisson’s ratio and material density (mass) to correspond with natural frequencies from the performed signal analysis of accelerometer signals. The influence of warping on the natural frequencies of the global finite element model was assumed small and the bridge’s torsional behaviour was modelled to follow Saint-Venant’s torsional theory.
A first preliminary estimation of modal damping ratios was included. The results indicated that natural frequencies were in accordance between modelling and signal analysis results, especially concerning high energy modes. Estimated damping ratios for the first vibration modes far exceeded the lower limit value specified in bridge design codes and railway bridge dynamic analysis recommendations.
