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…

Comparison of Different Construction Methods for Multi‐Storey Timber Buildings
2018
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2018 In this master thesis, different timber materials and construction methods are examined concern‐ing the application in multi‐storey timber buildings. Although wood as a construction material has many advantages, it is today only used very little for larger constructions, concrete and steel dominate the building industry. Planners and engi‐neers are often lacking necessary expertise to utilise timber in a modern, effective way. In order to promote the development of modern, efficient multi‐storey timber buildings, the goal of this master thesis is to contribute to a better understanding of the wood’s chara…

Design optimisation of a funnel-shaped floating dock for installation of offshore wind turbines
2020
Master's thesis in Civil and structural engineering (BYG508) Offshore wind power is a rapidly growing renewable energy industry and has a tremendous potentialof further expansion. Installation of offshore wind turbines is a challenging task. Floating windturbines are believed to be cost-effective solutions for deep water installation. This technologyis extremely sensitive to wave excitation during the installation process. As deep-water windfarms often are located in areas exposed to rough weather, innovative methods of installation areinvestigated. The floating dock concept has been proposed in recent studies in order to expand theweather window for installing spar floating wind turbines. …
Design and Analysis of a Novel Semi-submersible Floater Supporting a 5MW Wind Turbine
2021
Master's thesis in Civil and structural engineering (BYG508) The wind industry has been rapidly evolving in recent years, moving from onshore to offshorelocations. For deep waters, floating wind turbines are more cost-effective than bottom-fixed ones,and semi-submersible floating wind turbines are especially advantageous compared to other con-cepts because of their relatively small draft and good towability for installation. This masterthesis focuses on preliminary design and analysis of a novel semi-submersible floating wind turbinesupported by a twin fish floater and positioned by a single-point mooring system. Hydrostaticand hydrodynamic analysis are first carried out to select a floater…

Bestandighetsstudie av Ultra-High Performance Concrete (UHPC) : En forskning om påvirkningen av rissvidde, overdekning og eksponeringsmiljø med hensy…
2020
Master's thesis in Civil and structural engineering (BYG508) Ultra-High Performance Concrete (UHPC) was developed in research to increase the strength and durability of concrete. The material has shown remarkable ductility, durabilityand strength properties in laboratory tests, but has not beenmuch tested in practice. This master thesis presents an experiment to investigate the durability of UHPC in two marine environments in view of the risk of rebar corrosion. Factors under consideration are cover depth and crack width to observe how this will influence the penetration of aggressive substances that can cause corrosion. To investigate the corrosion state and chloride content, electrochemic…
