Masteroppgave bygg BYG508 - Universitetet i Agder 2019 Reinforced concrete is amongst the most used structural materials in the construction industry, due to its strength, applicability and formability. At the same time the environmental impacts caused by the use of concrete are significant. On the other hand, the use of cross-laminated timber (CLT) has increased as the focus on environmental gas emissions also increases. The aim of this Master thesis has therefore been to determine how the design process of a structural load bearing system can minimize the environmental footprint. To answer this, a thorough analysis of a 4-story, and a 6-story apartment building in “Kanalbyen” has been car…
Experimental and finite element analysis of the shear behaviour of UHPC beams
2019
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 The flexural behavior of reinforced concrete beams isobviously defined and can be managed with reasonableaccuracy.However, a solution has not been obtained for the shear capacity of beams, especially those without shear reinforcement, though numerous models have been established using different approaches. The reason is due to the complexity of shear behavior of reinforced concretebeams,where the load transfer through various componentsof concrete. In addition to this, there is also the effect of reinforcement and cross-section of the memberswhichis linked with dowel action and geometric parameters.All th…
Network arch bridge : Optimization of the arch applying simple loads
2019
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 This master thesis gives insight in structural behavior of network arch bridges. When designed with circular arches the bending moments tend to rise near the bridge ends. As suggestions for improving this problemtwo alternative arch geometriesare investigated; arch with elliptical shape anda three-center arch shape. The arch geometries are modelledwith different radius ratios.In addition,different variables are changed on the models which includes; arch rise, hanger inclination, number of hangers and the transition point between the curvatures.Two-dimensional numericalcalculations are doneusing structural…
Kontinuerlige betongelementbruer : Virkningen av byggetilstand på konstruktiv oppførsel og dimensjonerende krefter
2019
Masteroppgave bygg BYG508 - Universitetet i Agder 2019 The aim of this thesis is toexplore whateffect the construction state of a continuous prefabricated beam will have on the structural behaviour and design forces. This has been done by analysing Kvellaren bru located in Sandnes,when prefabricated beamsare used. The beams referencedin this thesis is based on preapproved prefabricated beams presented in the new manual V426. The beams presented are intended for simply supported beams, whereas the effect of making them continues hasbeenexamined. The analysis concludes that a continuous beam would be preferable to ensure an economicalstructure. The deformation of a continuousbeam when subject…

2021
Master's thesis in Civil and structural engineering (BYG508) The process of development for computer programs, is modified an updated continuously. Just in the last twenty years, both modelling-and calculation tools have developed to be able to handle and produce 3D models. Today, it is also possible to use parametric design for these work assignments. Parametric design produce algorithms to define the work tasks, that are to be done in the modelling-and calculation programs. This master thesis is therefore investigating how parametric modeling can generate a more efficient revision process, of the geometric-and static model, for design of bridge decks. To accomplish this, a study of litera…
Karakterisering og rensing av tunnelvann
2019
Masteroppgave bygg BYG508 - Universitetet i Agder 2019 This Project is a master thesis. The report is an addition to the preliminary project, which was made in the autumn of 2018. The research question of this project is: "How to solve the challenges related to polluted tunnel water?”During the project period a wide range of different methods dealingwith particle containing tunnel water has been studied. Analyses of coagulant chitosan have also been carried out. Sedimentation characteristics with a varied concentration of chitosan were analysed involvingsedimentation rate, suspended solids (SS), turbidity and particle analyses. A qualitative survey was also conducted to four respondents. Al…
Integrated drawingless workflow from design to installation
2021
Master's thesis in Civil and structural engineering (BYG508) In this master thesis, a methodology for demonstrating both the traditional and the digitalization of reinforcement production’s process for a structural system in an apartment building has been investigated. The purpose of this thesis is the workflow of reinforcementsprocess from the model to assembly on-site. AutoCAD as the traditional and Tekla/Revit as the digital with more focus on the reinforcement processes. Reinforcement in the structure is performed in both AutoCAD and Tekla. The ETABS have been used to analyse sections andto get out the quantities and volumes of reinforcements through this project. The first beam on gird…
Inkludere CO2-regnskap i 3D-modellen for veibyggingsprosjekter
2018
Masteroppgave bygg BYG508 - Universitetet i Agder 2018 For decades, Norwegian roads were constructed and planed by use of printout drawings. Today, as projects increase in scope and complexity, road construction has become a highly collaborative effort, with multiple disciplines working together to fulfil strict regulation requirements. It is due to this development that usage of digital tools in road and infrastructure engineering is more common. This master thesis takes a closer look at today’s possibilities in digital road construction design and on potential of expanding the usability by applying modern software development. Mainly, two separate cases have been investigated, a country r…
Bruk av FEM-modellering til kapasitetsundersøkelser av momentoverførende knutepunkter i stål
2021
Master's thesis in Civil and structural engineering (BYG508) Eurocode 3 provides a rough analytical method to estimate the capacity of a steel joint by derivingthe overall behavior from its components. Numerical methods such as the finite element method(FEM) enable accurate simulation of joint behavior. However, there is no direct guidelines inthe Eurocodes for utilizing numerical methods to document the capacity of moment-resisting steeljoints. This master thesis investigates how FEM can be used to evaluate and document the capacityof such joints. A literature review that includes relevant normative documentation and researcharticles dealing with the use of FEM has been carried out and a s…
