Respons i en etterspent skjærvegg fra jordskjelvlaster
(Master thesis, 2013)Det ble tatt utgangspunkt i en oppspent veggskive med slakkarmering. Oppgaven gikk ut på å studere hvordan den oppspente armeringen og slakkarmeringen samvirker, når veggskiven utsettes for seismiske påkjenninger.Spennarmeringen ... -
A Response Spectrum Analysis of Wind Deflection in Railway Overhead Contact Lines Using Pseudo-Excitation Method
(Peer reviewed; Journal article, 2021)The wind deflection of overhead contact lines (OCLs) challenges the stable and safe operation of electrified railways. The steady wind causes the static deflection of the contact line, while the fluctuating wind leads to ... -
Revealing the critical pore size for hydrogen storage via simultaneous enclathration and physisorption in activated carbon
(Peer reviewed; Journal article, 2024)Hydrogen hydrate is regarded as an ideal hydrogen storage medium, but it faces unsolved challenges related to its extreme formation and stabilization conditions. Recent experiments have demonstrated that utilizing porous ... -
Revealing the role of hydroxyl groups in the adhesive properties of DOPA derivatives
(Master thesis, 2023)Blant alle naturlige klebematerialer er det kjent at polyfenoler er de vanlige kjemiske ingrediensene som spiller en betydelig rolle i klebeegenskapene. Mer spesifikt består den avgjørende kjemiske strukturen til naturlige ... -
Review of Sprayability of Wet Sprayed Concrete
(Peer reviewed; Journal article, 2020)Wet sprayed concrete quality is affected by more production factors than cast concrete, particularly due to the propulsion through the nozzle and the flash set caused by the set accelerator. Practitioners often use the ... -

(Peer reviewed; Journal article, 2023)This review paper highlights the most fundamental state of knowledge regarding the fatigue ofconcrete that is available through the literature over the last decades and reveals the areas that areneeded for further ... -
A Review on Fatigue Performance of Concrete Structures Part II, Material Parameters and Environmental Factors
(Peer reviewed; Journal article, 2023)Fatigue is a critical issue for concrete structures subjected to repetitive and varying loads,particularly in infrastructure and transportation systems. This review paper presents acomprehensive overview of the current ... -
Reviewing the Potential of Phase Change Materials in Concrete Pavements for Anti-Freezing Capabilities and Urban Heat Island Mitigation
(Peer reviewed; Journal article, 2023)This study provides an overview of how phase change materials (PCMs) can improve the resistance of concrete pavement to freeze–thaw cycles and mitigate the urban heat island (UHI) effect. The investigation covers different ... -
Revisiting concrete frost salt scaling: On the role of the frozen salt solution micro-structure
(Peer reviewed; Journal article, 2022)We simulate the glue-spall stress due to mechanical interactions between a frozen saline solution (brine-ice composite) and a non-air entrained concrete surface including the impact of the micro-structure of the frozen ... -
Rheology and printability of matrix: effect of filler from manufactured sand vs. copolymer
(Master thesis, 2023)Denne studien undersøker hvordan ulike mengder fyllstoff og superplastifiseringsmiddel påvirker reologi og printbarhet til sementpasta som er modifisert med fyllstoff. Fire metoder ble brukt for å undersøke effekten av ... -
