A multi-method approach to explore risk factors in truck-bicycle encounters
(Doctoral theses at NTNU;2018:40, Doctoral thesis, 2018)Currently, the numbers of cyclists are increasing in many cities worldwide. People are encouraged and motivated to cycle, as it improves their health, reduces the negative effect of car traffic and creates more liveable ... -
Assessment of monopiles for lifetime extension of offshore wind turbines
(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 ... -
Bridge Foundations at Large Water Depths
(Doctoral theses at NTNU;2018:76, Doctoral thesis, 2018)The Norwegian Public Roads Administration (NPRA) plans for a significant upgrade of the E-39 highway route along the west coast of Norway between Kristiansand and Trondheim, where the ferry connections will be replaced by ... -
Climate adaptation of pitched wooden roofs
(Doctoral theses at NTNU;2018:124, Doctoral thesis, 2018)In this thesis, wooden roofs are defined as roof structures where the load-bearing structure consists of wood. Such structures are normally built with a ventilated air cavity between the underlayer roof and the roofing. ... -
Climate robust buildings: towards buildings with a robust energy performance under climate change
(Doctoral theses at NTNU;2019:233, Doctoral thesis, 2019)Building performance simulation (BPS) is a powerful tool allowing building designers to estimate the behavior of buildings and assess the impacts of their design decisions on their performance. BPS requires large number ... -
Dynamic Analysis and Structural Optimization of Support Structures for bottom-fixed Offshore Wind Turbines
(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 ... -
Expanding knowledge base for photovoltaic systems’ integration by contributing to the development of an experimental testing method for evaluation of their performance as climate screens
(Doctoral theses at NTNU;2023:428, Doctoral thesis, 2023)Building-integrated photovoltaic (BIPV) is a vital element of zero energy or zero emission buildings (ZEB). BIPV systems are integrated into the building envelope and generate electricity on-site during the expected service ... -
Hydrologic and metal removal potential of filtering swales for stormwater control in cold climates
(Doctoral theses at NTNU;2018:37, Doctoral thesis, 2018)Runoff from urban areas carries a wide range of pollutants both particle-bound and dissolved. Dissolved pollutants are generally more mobile and bioavailable as well as more difficult to remove by conventional infiltration ... -
Hydrologic performance modelling of green roofs using conceptual and data-driven modelling tools
(Doctoral theses at NTNU;2023:425, Doctoral thesis, 2023)With climate change and rapid urbanization, the amount and intensity of stormwater flow are expected to increase, leading to frequent failures and overflows of conventional stormwater infrastructures. To address this issue, ... -
Iteratively coupled implicit dynamic MPM-FVM
(Doctoral theses at NTNU;2019:19, Doctoral thesis, 2019)Several geotechnical engineering problems involve the interaction between deformation of the soil skeleton and the development of pore water pressures. Very often the deformations are considered to be small, which opens ... -
Modelling of skirted foundations for offshore wind turbines
(Doctoral theses at NTNU;2018:140, Doctoral thesis, 2018)The thesis focuses on the modelling of the response of shallow skirted foundations supporting offshore wind turbines (OWT). OWT-structures need to be optimized in design to reduce the cost of energy from offshore wind ... -
Moisture performance of thermally insulated basement walls in cold climates
(Doctoral theses at NTNU;2022:298, Doctoral thesis, 2022)Climate change entails frequent and intense events of heavy rainfall and rain-induced floods in many regions with cold climates. In addition, present solutions for stormwater management involve the infiltration of surface ... -
Optimal design of offshore wind turbine support structures under uncertainty - Towards a framework for practical reliability-based design optimization
(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 ... -
Optimising Construction Projects as Value Delivery Systems - Expanding the theoretical foundation
(Doctoral theses at NTNU;2019:287, Doctoral thesis, 2019)In the last few decades, the advent of Lean Construction (LC) has been a driving force behind a paradigm shift in the construction industry. One of the greatest consequences has been the realisation that projects are indeed ... -
The impact of fixed link projects to islands on accessibility and population development
(Doctoral theses at NTNU;2020:50, Doctoral thesis, 2020)Norway has a long coastline, with many islands and fjords. Ferries play a vital role in enabling people to access these islands and to cross the fjords. However, in recent decades, several ferry services have been replaced ... -
The thermal conductivity of a melting snow layer and its effect on temperature and surface condition modelling of heated pavements
(Doctoral theses at NTNU;2018:29, Doctoral thesis, 2018)During winter time snow and frost formation on roads can cause slippery conditions leading to reduced safety and decreased mobility. To prevent slippery conditions winter maintenance measures are taken such as snow ploughing, ... -
Thermo-hydro-mechanical Simulation of Frost Heave using Extended Finite Element Method
(Doctoral theses at NTNU;2024:145, Doctoral thesis, 2024)The starting point of this work is a conceptual model for frost heave based on nonequilibrium thermodynamics. According to the theory, the temperature gradient in the soil under frozen condition is the main driving force ...
