Investigations on the Development of a Cost Model for Large Infrastructure Elements, Exemplified by the Proposal for an Aluminium Suspension Bridge over the Langenuen Fjord in Norway
(Master thesis, 2021)Aluminium har et stort potensial som materiale i store konstruksjonsprosjekter, spesielt med tanke på dens egenskaper som kan gi redusert vedlikehold og økt levetid på konstruksjonene. Likevel er bruken av aluminium liten ... -
Investigations on the feasibility of the CWE method to verify potential alkali release from aggregates in Norwegian field concrete
(Chapter, 2021)Concrete elements exposed for 26 years to seawater spray and deicing salts along a road close to Sandnessjøen in Norway were investigated. Concrete cores from 4 elements with different binder compositions (A: 100 % Portland ... -
Investigations on the Sustainable Resource Use of Swiss Timber
(Peer reviewed; Journal article, 2021)In Switzerland, the advantages of timber buildings for the climate are broadly discussed. In the following paper, a comparative sustainability assessment of four building alternatives is presented. Especially the contribution ... -
Investigative Study on Method for Approximating Nonlinear Material Behavior in Reinforced Concrete Structures Subjected to Seismic Ground Motions
(Master thesis, 2019)Ikke-lineære tidsplansanalyser blir generelt ansett som den mest nøyaktige metoden for å anal- ysere responsen til konstruksjoner utsatt for seismiske laster. Dessverre er denne typen analyser svært krevende beregningsmessig, ... -
Investing for Impact. Lessons with the Norwegian State Project Model and the first ivvestment projects that have been subjected to external quality assurance
(Concept rapport;36, Book, 2013)The report provides a description of the Norwegian State Project Model, also referred to as the government’s scheme for external quality assurance of major public investment projects (the QA scheme). The scheme was introduced ... -
Investorers vurdering av prosjekters godhet
(Concept Rapport, 0804-5585; 20, Research report, 2007)Rapporten studerer grunnlaget for beslutninger om å investere i et prosjekt. Studien tar utgangspunkt i de vurderinger av prosjekters godhet som utføres av den private investor ved større realinvesteringer. Basert på innsikt ... -
