Hållbara ytbeläggningar i parkeringshus : En undersökning av olika beläggningssystem efter 5 till 10 års drift / Sustainable Coatings in Parking Garages : A Survey of Different Coating Systems After 5 to 10 Years of Operation

Jin, Jacky, Matskin, Artur January 2019 (has links)
Parkeringsanläggningar utsätts ständigt av belastningar från körande fordon och kloridangrepp under vinterperioden. Påföljden av det blir kostsamma skador på betongkonstruktionen, främst vid uppkomna sprickor. Kloridinträngning medför att armeringsjärnen korroderar och försvagar underliggande betongkonstruktionen. Ersättning av de korroderade armeringsjärnen samt betonglagningar är kostsamt för Stockholm Parkering. Lösningen är att förbehandla den oskyddade betongen och applicera en ytbeläggning ovanför. De vanligaste som finns i Sverige är cementbaserade, bitumenbaserade och härdplastbaserade ytbeläggningar. Det finns inga direktiv för val när det gäller ytbeläggningar. Eftersom alla ytbeläggningar har olika egenskaper är det för- och nackdelar som beställaren ska värdera beroende på parkeringshusets förutsättningar som utformningen, trafikbelastningen och om det är grundplattan eller mellanbjälklaget som ytbeläggningen appliceras på. Förutom materialet är utförandet också viktigt. En väl utförd förbehandling av betongunderlaget och noggrann utläggning av ytbeläggningen minskar risken för uppkomst av skador i framtiden och därmed reparationskostnaderna. Syftet med examensarbetet är att undersöka olika ytbeläggningar som har varit i drift 5 till 10 år för att sedan identifiera och kartlägga skador som har uppkommit på dem. I denna rapport har fem parkeringsanläggningar valts ut som fallstudier för att undersöka de vanligaste ytbeläggningarna som används idag i Stockholm Parkerings parkeringsanläggningar. Utifrån litteraturstudier, intervjuer med olika parter i respektive projekt, observationer som utfördes under studiebesöken och jämförelse mellan fallstudier dras slutsatser för att hitta den hållbaraste ytbeläggningen. Slutligen skapas en lathund för att förenkla valet av ytbeläggningar för parkeringsanläggningar med olika förutsättningar. / Parking facilities are constantly exposed to traffic loads from driving vehicles and chloride attacks during the winter period. The consequence of this is costly damage to the concrete structure, especially in the event of cracks. Chloride penetration causes the reinforcement bars to corrode and weaken the underlying concrete structure. Replacement of the corroded reinforcement bars and concrete repairs are costly for Stockholm Parking. The solution is to pretreat the unprotected concrete and apply a coating above it. The most common coatings found in Sweden are cement-based, bitumen-based and thermoset-based coatings. There is no clear choice when it comes to coatings since they all have different properties. The advantages and disadvantages of different coatings that the customer must value depend on such conditions of the parking garage as the shaping, the traffic load and whether it is the base plate or the intermediate floor. Besides the material, the execution is also important. A well done pretreatment of the concrete substrate and meticulous laying of the coating reduces the possibility of the occurrence of damage in the future and thereby the repair costs. The purpose of the thesis project was investigation of various coatings systems that have been in operation for 5 to 10 years and identification and mapping damages that occur to them. In this report, five parking facilities have been selected as case studies to investigate the most common coatings used today in Stockholm Parkering parking facilities. Based on literature studies, interviews with various parties in each project, observations made on study visits and comparison between case studies conclusions were drawn about the most sustainable surface coating systems. Finally, a guidance is created to simplify the choice of coating systems for parking facilities with different conditions.

Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

Benosmane, Zakariya January 2022 (has links)
Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. The inspectionof such structures is compulsory to assess their state and plan repairing operations ifnecessary. The main inspection method has for long been field inspection, however, thismethod presents several problems, namely, the complexity to access some parts of thestructures and the subjectivity of the decisions. These difficulties make the operationtime-consuming and prone to error, thus a need for a new methodology that would benumerical and more automated.One of the damages that affect the carrying capacity the most in concrete structuresare surface-cracks. In this work, the focus is brought on this type of damage and a solutionfor the inspection methodology is presented and applied to a case study.The methodology first consists in using the photogrammetry technology, which allows theproduction of a 3D point cloud model of the structure by taking multiple pictures of it usingUAVs to facilitate access to its complex parts. From this point cloud, surface-openingcracks could be visualized and an orthoimage featuring the damages can be produced.Then, an image-based crack detection program will be used on the orthoimage to extractthe crack. From this, a program is developed to find the coordinates of the crack in thestructure and to process the model of the crack. Then a program is made to importthe crack model to a finite element software, and from there the extended finite elementmethod (XFEM) combined with the concrete damaged plasticity (CDP) method will beused to assess the carrying capacity of the structure and to study the evolution of itscrack pattern.The methodology was tested in a case study. In this case study, a steel-reinforced concretebeam was damaged and all of the methodology steps were applied. An adaptationto some steps was needed due to challenges raised by the test set-up.A three-point bending experience was carried out on the beam while recording the forceand displacement data and the crack pattern evolution. Numerically, this experience wasreproduced and relevant results were extracted and compared to the experimental ones.Differences in the carrying capacity were observed and multiple numerical analyses werecarried out to test the taken assumptions and detect the source of error. On the otherhand, for the crack pattern, satisfying results were achieved. Moreover, the degree of thedetailing in the crack model and its effect on the results is discussed.Globally, it can be concluded that the methodology can effectively in a numericalsemi-automated way capture the surface cracks in concrete structures and import theirmodel to a finite element software to apply analyses to assess the capacity of the damagedstructure and study the evolution of the cracks.This methodology could be further developed in the future by including more technologiessuch as lasergrammetry to make it go from a 2D surface-based damage analysis to a 3Danalysis. Moreover, criteria specialized for inspection and repairing purposes could becreated and implemented in the methodology.

Chaperon

London Ante Paris, Patricia 17 November 2023 (has links)
Eine polymorphe Orbitalskulptur, die aus einer 3D-Kohlenstoff -Betonstruktur besteht, die von einem Polypeptidnetzwerk inspiriert ist, das ein geringeres Gewicht und eine geringere Zähigkeit bewirkt und auf einer überfluteten Stadtstraße steht, die von der anthropozentrischen Wärmeakkzeleration herrührt. - Meine künstlerische Praxis besteht aus partizipativen Performances, Malerei und Skulptur im Zusammenspiel von Tanz, Musik, wacher Zeitgenossenschaft und farbintensiven Werken, denn alles Sichtbare ist nur durch die Farbe begehrenswert.
