Standardisering av brokonstruksjoner for nasjonale hovedveier
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Standardization is currently not being utilized much in the Norwegian road building industry compared to the rest of the construction industry and road construction abroad. To harvest the potential benefits, it is interesting to determine how to increase the use of standardization in road building. The aim of this master’s thesis is to determine how to make use of standardized concrete bridges for the construction of new national highways. To investigate this, the thesis has established knowledge on today’s situation and found dominant obstacles towards a more widespread use of standardized bridge solutions. The Norwegian Public Roads A…
Dimensjonering av slank balkong i Ultra-High Performance Fibre-Reinforced Concrete
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 As part of the fifth and final year in civil engineering at University of Agder, this master’s thesis has been composed. This report was written during the spring semester of 2017. The purpose of this thesis was to dimension a slim balcony in UHPFRC. Nor Element wanted to be able to produce slim balconies in their own production facilities. Nor Element is currently producing balconies, but these have thicker cross sections. This master’s thesis involves a literature study and a dimension process. In the literature study the relevant guidelines and Eurocodes are presented. The study contains relevant formulas and recommendations needed t…
Standardiserte konstruksjonselementer av fiberarmert polymer for vegbru : Design og dimensjonering av elementer for standardisering og bruk i vegbruer
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 This thesis is addressing the possibility for use of fiber reinforced polymers (FRP) in bridge constructions in Norway. The aim is to design an FRP section that can perform as both structural support and decking on the bridge, in a similar way as often is done with concrete. The advances of using FRP composites is that it is possible to make the bridge sections a lot lighter, and consequently possible to fabricate them in remote locations and transport them to the construction site. This will make the time necessary for construction on site a lot shorter in cases where old bridges need replacement. To make FRP-composite bridges economic…
Rehabilitering av antikvarisk betongkonstruksjon fra perioden 1926-1938 : Vurdering av rehabiliteringstiltak og restkapasitet for Ingierstrand bad, b…

Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Traditionally restoration of antiquarian concrete constructions has been a prominent topic in Norwegian context. This topic has been given more attention, as more concrete constructions and reinforced concrete constructions have been preserved. In this thesis a case-study were done of Ingierstrand bad. A central part of the restoration of antiquarian concrete constructions is to control the capacity of the concrete against occurring stresses. We have in this thesis theoretically controlled the capacity of the standard being used during projecting and building, and that of today’s standard. We suggested the actions of restoration we thin…
En risikovurdering ved bruk av svalgang som rømningsvei : bruk av FDS til å undersøke brannsikkerheten ved fravikelser fra preaksepterte ytelser
2016
Masteroppgave bygg - Universitetet i Agder 2016 The purpose of this master thesis is to investigate the tenability limits on the egress path on an access balcony when not following all the given pre accepted solutions. The analysis construction deviates from some of the pre accepted solutions given for TEK10 to investigate if the fire safety level is satisfying. According to the standard NS 3901 Requirements for risk assessment of fire in construction works, a comparative qualitative analysis has been done by using FDS. The conditions that are analyzed is the time for critical temperature and heat radiation to occur where fire simulations in FDS has given the available safe egress time for …

Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Fiber reinforced composites have many good properties, but also many applications that make it vulnerable to accidental loads, like impact damage and fire. The problem with this is that minor and larger damage can be difficult to observe and a challenge to inspect on the spot. All materials exposed to fire, or high temperatures will expand, which can cause instability and large deformations. Several studies have examined the behavior of composites under these typical accidental loads individually, but none or very few have investigated when they occur simultaneously or the overall effect they provide. To address the problem in this thes…
Livsløpsvurdering og dimensjonering av stålog limtrebue i en nettverksbuebru
2016
Masteroppgave bygg - Universitetet i Agder 2016 This master thesis focuses on the design and life cycle assessment (LCA) of a network arch bridge. The arch is designed and compared by using two different materials, steel and gluelam. This study is carried out on the behalf of Statens vegvesen, Region øst, and serves as the graduate thesis for master degree in Civil Engineering at the University of Agder. The network arch bridge is part of E16 and is located at Oppstadåa. The bridge carries four lanes, which results in a 21 meters wide deck. The span of the bridge is 120 meters. Three different network arch bridges alternatives have been designed in this thesis. The original network arch bri…
