Prediction of Vehicle Crashworthiness Parameters Using Piecewise Lumped Parameters and Finite Element Models
(Journal article; Peer reviewed, 2018)Estimating the vehicle crashworthiness experimentally is expensive and time-consuming. For these reasons, different modelling approaches are utilised to predict the vehicle behaviour and reduce the need for full-scale crash ... -
A predictive model unifying hydrogen enhanced plasticity and decohesion
(Peer reviewed; Journal article, 2022)The detrimental effect of hydrogen on metals which manifests itself as a transition from a ductile to a brittle failure mode is, for the first time, incorporated into a unified continuum-scale predictive framework. The ... -
Predictive Models for Earthquake Response of Clay and Sensitive Clay Slopes
(Geotechnical, Geological and Earthquake Engineering;Predictive Models for Earthquake Response of Clay and Sensitive Clay Slopes, Journal article; Peer reviewed, 2014)Earthquake-induced permanent displacement and shear strain are suitable indicators in assessing the seismic stability of slopes. In this paper, predictive models for the permanent displacement and shear strain as functions ... -
Predictive strength of ready-mixed concrete: Exemplified using data from the Norwegian market
(Journal article; Peer reviewed, 2018)A hierarchical model for the variability of material properties in ready‐mixed concrete is formulated. The model distinguishes between variation on the batch, recipe, plant, producer, durability class, strength class, and ... -
Preparation system, salt scaling, absorption and internal damage in the CEN/TS 12390-9 concrete frost test
(Master thesis, 2017)Experiments show that the most promising materials to replace key point 2 and 3 in the CEN/TS 12390-9 standard is by using a combination of Sitko Elastic butyl tape and adhesives. The adhesives are "SikaFlex 11FC" and ... -
Pressure Perpendicular to the Grain in Wooden Sills: Numerical Studies of Softening and Failure in Abaqus
(Master thesis, 2012)Joints with pressure perpendicular to the grain are a common occurrence in wooden structures. While the making of such a joint is very simple, dimensioning it is difficult: The load configuration causes a mix of ductile ... -
Prinsipper og metoder til reparasjon av betong - Reparasjonsmetoder anvendt i Statens vegvesen
(Master thesis, 2017)The Norwegian Public Roads Administration as a government agency has a large literature collection dealing with concrete repair, but the literature spread in several places. The literature is very comprehensive and divided ... -
Probabilistic autoencoder-based bridge damage assessment using train-induced responses
(Peer reviewed; Journal article, 2024)Structural health monitoring (SHM) systems have been increasingly employed to continually assess the current state of bridges. However, the vast amounts of sensor data generated by SHM systems, along with constantly changing ... -
Probabilistic Design of Sustainable Reinforced Concrete Infrastructure Repairs Using SIPmath
(Peer reviewed; Journal article, 2020)The design, construction, and operation of civil infrastructure that is more environmentally, socially, and economically responsible over its life cycle from extraction of raw materials to end of life is increasingly ... -
Probabilistic Methods in Management and Inspection of Buried Steel Pipe Bridges
(Master thesis, 2018)Management and inspection of existing bridges involve decision making. Loading, resistance and deterioration of bridges are uncertain. Inspection reduces uncertainty, but the uncertainty is usually not considered on a ... -

Probabilistic modelling of wind induced load effects for suspension bridges with emphasis on long-term extreme value analysis
(Doctoral theses at NTNU;2022:218, Doctoral thesis, 2022)Economic development has gradually promoted an increase in the demand for and size of long-span bridges worldwide. A tangible example of such development is the Coastal Highway Route E39 led by the Norwegian Public Roads ... -
Probabilistic Seismic Hazard Analysis for Offshore Bangladesh Including Fault Sources
(Chapter, 2018)This paper presents a probabilistic seismic hazard analysis (PSHA) for a site offshore Maheshkhali Island, Bangladesh. The tectonic setting of the area is complex, and the PSHA includes active crustal faults, megathrust ... -
Probability-based assessment of the Stavå bridge
(Master thesis, 2020)Denne masteroppgaven handler om beslutningsprosessen angående hva man skal gjøre med Stavåbrua. Hovedmålet med oppgaven er å finne ut hva man skal gjøre med Stavåbrua. Oppgaven tar ikke bare for seg på de rene konstrukjo ... -
Production and Documentation of Frost Durable High-Volume Fly Ash Concrete: air entrainment, cracking and scaling in performance testing
(Doctoral theses at NTNU;2020:366, Doctoral thesis, 2020)Concrete with moderate replacement levels of fly ash (FA) has been used for decades and considered sustainable in harsh environments. If the replacement levels become high (FA/C > 40…50%), the range of properties from fresh ... -
Programvarestyrt dimensjonering av trebjelke med innsnitt
(Master thesis, 2011)I denne oppgaven er det utviklet et program for dimensjonering av trebjelke med innsnitt i bruddgrensetilstanden. Dataprogrammet er utviklet i MATLABR2010b, og er kompilert til et frittstående program ved hjelp av MATLAB ... -
Progressive collapse of buildings caused by explosion
(Master thesis, 2016)Extreme loading may cause failure or damage to structural building members. Redistribution of forces might propagate the local failure into a complete or partial progressive collapse of the building. The prevailing method ... -
Projectile Impact on Plain and Reinforced Concrete Slabs
(Peer reviewed; Journal article, 2023)Reinforced concrete is a material frequently used in protective structures and infrastructure exposed to extreme loading. In this study, the ballistic perforation resistance of 100 mm thick plain and reinforced concrete ... -
