A probabilistic-based methodology for evaluation of timber facade constructions - The Performance to withstand biodeterioration
Gradeci, Klodian (Doctoral theses at NTNU;2018:69, Doctoral thesis, 2018)Mould and decay are biodeterioration phenomena that jeopardize the integrity, functionality and durability of timber façade constructions. Accounting for them during the design stage is crucial for the prevention of social ... -
Analysis project of embodied carbon emissions in building structures with reinforced concrete components
Mir Díaz, Carlos (Master thesis, 2023)Det bygde miljøet er av åpenbar betydning for vår bærekraftige utvikling, siden det ikke bare legger til rette for sosial aktivitet, men også spiller en betydelig rolle i den globale omsetningen av økonomiske og miljømessige ... -
Assessment of Existing Bridges in Norway
Bjarnadottir, Thorey Petra (Master thesis, 2022)The Norwegian Public Roads Administration maintains the road network in Norway. The administration has its own guidelines for the inspection and capacity assessment of bridges, of which maintenance decisions are based on. ... -
Assessment of monopiles for lifetime extension of offshore wind turbines
Ziegler, Lisa (Doctoral theses at NTNU;2018:209, Doctoral thesis, 2018)Offshore wind is a fast-growing industry contributing to reduce CO2 emissions. Although most offshore wind turbines are still young today, we will face a significant fleet of ageing assets in the near future. The question ... -
Degradation Mechanisms of Chain Links in Offshore Mooring Lines
Tømmervåg, Kristin Hanem (Master thesis, 2016)Degradation mechanisms contributing to mooring line failures are identified and discussed with respect to the service conditions for the defined mooring line segments. Corrosion, environmental assisted cracking (EAC) and ... -
Dynamic Analysis and Structural Optimization of Support Structures for bottom-fixed Offshore Wind Turbines
Schafhirt, Sebastian (Doctoral theses at NTNU ;2017:363, Doctoral thesis, 2017)Wind energy is recognized as a reliable and affordable source of energy for generating electricity. Up to date most of the wind energy capacity is installed onshore, but legal regulations and a shortage of potential locations ... -
Growth of Fatigue Cracks in Mooring Line Chains
Hove, Martin (Master thesis, 2016)This master thesis is the continuation of a project work conducted during the fall of 2015, and is part of a series of studies investigating the effect of surface condition on the fatigue life of mooring chains. The study ... -
Integrated design and maintenance of deteriorating structural systems
Espinosa, Jorge Mendoza (Doctoral theses at NTNU;2021:351, Doctoral thesis, 2021)Large structural systems such as bridges and offshore structures are subject to deterioration processes during their service life. Specifically, fatigue and corrosion are of major concern. To ensure that the structures are ... -
Multiaxial fatigue analysis of offshore mooring chains, considering the effects of residual stresses and corrosion pits
Zarandi, Ershad P. (Doctoral theses at NTNU;2020:337, Doctoral thesis, 2020)The integrity of the mooring lines used to anchor offshore facilities and floating platforms has been always desired while its continuous achievement has been challenging. Many mooring line failures have occurred in the ... -
Numerical Investigation of 3D Scanned Mooring Chains - Effects of Stress Concentrations from Corrosion Pits
Bache, Truls Johan Martin Braut (Master thesis, 2017)This thesis aims to numerically evaluate severe corrosion pits on offshore mooring chain. Pitting corrosion is considered a significant degradation mechanism as cracks tend to nucleate and propagate in areas of high stress ... -
Optimal design of offshore wind turbine support structures under uncertainty - Towards a framework for practical reliability-based design optimization
Stieng, Lars Einar Sørensen (Doctoral theses at NTNU;2020:33, Doctoral thesis, 2020)As part of efforts to reduce the costs of offshore wind energy, optimization methods for the design of support structures are an important contribution. In order to account for the uncertainties in the design process without ... -
Probabilistic modelling of building stock properties for urban mining
Dittrich, Nils Maximilian; Hingorani, Ramon; Köhler, Jochen (Chapter, 2024) -
Reliability Analysis of Reinforced Concrete using Non-Linear Finite Element Analysis
Henriksen, Erlend Knudsen; Bjerva, Mats Gruber Bech; Lindgren, Guro; Afzal, Noman (Master thesis, 2016)The purpose of the thesis is to investigate methods that may be used for assessing the reliability in large concrete structures in combination with non-linear nite element analyses (NLFEA). Reliability methods are applied ... -
Reliability assessments of concrete structures using non-linear finite element analyses
Strand, Arne; Eklund, Hanna; Skorve, Astrid (Master thesis, 2017)Reliability assessment of slender concrete columns using Non-linear finite element analysis (NLFEA) is studied in this thesis. Several reliability methods in combination with NLFEA are applied and discussed to assess the ... -
Risk and Reliability Based Calibration of Structural Design Codes: Principles and Applications
Baravalle, Michele (Doctoral theses at NTNU;2017:342, Doctoral thesis, 2017)Structures and infrastructures are essential for most societal activities and are required to be safe, as well as economically and environmentally sustainable. At the same time, societal resources of all kinds are limited. ...
