On Creep during Primary Consolidation of Clays
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:203, Doctoral thesis, 2011)Soft clay deposits are characterized by their strong tendency to undergo significant creep deformation even during the primary consolidation phase. This creep behaviour is usually studied based on information obtained from ... -
On Determination of Gmax by Bender Element and Cross-Hole Testing
(Master thesis, 2014)The small-strain shear modulus, Gmax, is an important parameter in geodynamic problems and for advanced modelling. Gmax is influenced by several factors, which complicates the assessment and interpretation of test results. ... -
On engineering characterisation of a low plastic sensitive soft clay
(Chapter, 2015)In central Norway, the soft clays can be extremely sensitive to disturbance during sampling and preparation for laboratory testing. In this paper a low plastic sensitive soft clay from Klett is presented. It is challenging ... -
On Fatigue Damage Assessment for Offshore Support Structures with Tubular Joints
(Journal article; Peer reviewed, 2016)The hot spot stress approach is commonly used for fatigue lifetime estimation of tubular joints. The standard approach consists of the linear superposition of stress components from axial, in-plane, and out of plane action, ... -
On gradient-based optimization of jacket structures for offshore wind turbines
(Journal article; Peer reviewed, 2018)During the bidding or very early design phases of jacket structures for offshore wind turbines, there may be very limited information available on meteorological conditions, soil conditions, turbine specifications, etc. ... -
On modelling of anisotropic undrained strength for non-horizontal terrain
(Chapter, 2018)Low plasticity soft clays show pronounced variation in undrained shear strength with the direction of loading. The active undrained shear strength (A) is significantly larger than the direct shear strength (D), which again ... -
On Numerical Simulations of Progressive Failure and Localized Deformation
(Master thesis, 2010)Soft sensitive clays are present in some of the most populated parts of Norway, and large slides in such clays have ahuge damage potential. It is thus important to understand their behavior and to be able to calculate their ... -
On Numerical Three-Dimensional Simulations of a Circular Retaining Shaft
(Master thesis, 2011)Midgardsormen is an ongoing upgrade of the storm water system in Oslo, managed by the Water and Sewer Administration in Oslo. Norconsult AS is geotechnical consultant to the project. As part of this project a circular ... -
On occupant-centric building performance metrics
(Journal article; Peer reviewed, 2017)Existing building performance metrics cover a wide variety of domains including energy performance, equipment performance, electric lighting, indoor environmental quality, capital and operating costs, and environmental ... -
On random subspace optimization-based hybrid computing models predicting the california bearing ratio of soils
(Peer reviewed; Journal article, 2021)The California Bearing Ratio (CBR) is an important index for evaluating the bearing capacity of pavement subgrade materials. In this research, random subspace optimization-based hybrid computing models were trained and ... -
On Shear Wave Velocity Testing in Clay
(Master thesis, 2015)The soil stiffness at small strains is an important parameter for settlement predictions and for understanding soil behaviour under seismic/dynamic loading. The small strain stiffness is usually found from the shear wave ... -
On some methods of downward continuation of mean free-air gravity anomaly
(Journal article, 1998)This paper investigates four methods of downward continuation of free-air gravity anomalies to sea-level, an iterative process based on the Poisson's integral, a linear simple formula, a method based on the Pellinen ... -
On strain-rate dependent properties of model ice for simulating ice-induced vibrations
(Master thesis, 2021)The subject of ice-induced vibrations on bottom-founded vertically sided offshore structures has gained renewed interest with the growth of the offshore wind industry, stimulated by many nations committing to ambitious ... -
On the concept of sustainability – assessing the sustainability of large public infrastructure investment projects
(Journal article; Peer reviewed, 2014)Assessing the sustainability of large public investment projects within the general framework of three-pillar thinking is a complex affair. Such ventures involve multiple actors – e.g. planners from various disciplines ... -
On the convexity of yield and potential surfaces in rotational hardening critical state models
(Chapter, 2018)This article shows that a common formulation often used for an anisotropic modified cam clay yield and potential surface with a modified Lode angle dependency may become concave for high values of anisotropy. Concave ... -
On the Earth Pressure Coefficient at Rest During Creep
(Master thesis, 2015)Many geotechnical problems requires assumptions regarding the initial stress state in the soil to be made. The earth pressure coefficient at rest, K0, describes the relationship between horizontal and vertical effective ... -
On the Feasibility of Real-time Sea Level Monitoring using Ground-based GNSS-Reflectometry Measurements
(Master thesis, 2020)GNSS Reflektometri (GNSS-R) er en fjernmålingsteknikk som har fått mye oppmerksomhet i nyere tid. I denne avhandlingen blir teorien bak GNSS reflektometri presentert, og et eksperiment er gjennomført for å vurdere mulighetene ... -
On the ice and wind conditions in the northern part of the Gulf of Bothnia leading ice-induced vibrations
(Chapter, 2020)In ice infested regions drift ice can give serious damage to offshore structures and ships. The origin of the drifting ice is the winds and the currents. However, it is known that the Gulf of Bothnia does not have strong ... -
On the influence of input data uncertainty on sewer deterioration models – a case study in Norway
(Peer reviewed; Journal article, 2021)Visual inspection is currently the industry standard for assessing sewer and stormwater pipelines – a method prone to uncertainties as shown by previous studies. The data gathered from the visual inspection procedures is ... -
On the isotache viscous modelling of clay behaviour using the hyperplasticity approach
