Assessing optimal water quality monitoring network in road construction using integrated information-theoretic techniques
2020
Author´s accepted manuscript. The environmental impacts of road construction on the aquatic environment necessitate the monitoring of receiving water quality. The main contribution of the paper is developing a feasible methodology for spatial optimization of the water quality monitoring network (WQMN) in surface water during road construction using the field data. First, using the Canadian Council of Ministers of the Environment (CCME) method, the water quality index (WQI) was computed in each potential monitoring station during construction. Then, the integrated form of the information-theoretic techniques consists of the transinformation entropy (TE), and the value of information (VOI) we…
Bruk av FEM-modellering til kapasitetsundersøkelser av momentoverførende knutepunkter i stål
2021
Master's thesis in Civil and structural engineering (BYG508) Eurocode 3 provides a rough analytical method to estimate the capacity of a steel joint by derivingthe overall behavior from its components. Numerical methods such as the finite element method(FEM) enable accurate simulation of joint behavior. However, there is no direct guidelines inthe Eurocodes for utilizing numerical methods to document the capacity of moment-resisting steeljoints. This master thesis investigates how FEM can be used to evaluate and document the capacityof such joints. A literature review that includes relevant normative documentation and researcharticles dealing with the use of FEM has been carried out and a s…

Comparison of Different Construction Methods for Multi‐Storey Timber Buildings
2018
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2018 In this master thesis, different timber materials and construction methods are examined concern‐ing the application in multi‐storey timber buildings. Although wood as a construction material has many advantages, it is today only used very little for larger constructions, concrete and steel dominate the building industry. Planners and engi‐neers are often lacking necessary expertise to utilise timber in a modern, effective way. In order to promote the development of modern, efficient multi‐storey timber buildings, the goal of this master thesis is to contribute to a better understanding of the wood’s chara…

From Waste to Resource – Utilising Residue from Ready-Made Concrete as New Aggregate
2021
Abstract A new admixture is available, to reduce the sludge produced from the cleansing of production and transportation equipment in the fresh concrete industry. The result is agglomerations of hardening concrete, that might be utilised for aggregate. Utilisation depends on adequate properties. This paper reports from investigations on the physical and mechanical properties of the aggregate and discussions on the performance relative to natural and recycled aggregates and towards requirements for utilisation. The findings indicate substantial potential for utilisation, supporting the reduction of waste for deposit and development of the concrete industry towards a circular economy.
Sustainable Approaches for Highway Runoff Management During Construction and Operation
2022
Paper V and paper VI have not been published yet. Environmentally friendly approaches for highway runoff management during construction and operation are considered in this project. First, the state of the art in runoff management in terms of characterization, treatment, and modeling approaches were surveyed, and knowledge gaps were identified. Then, the characterization and treatment of tunneling wastewater (by natural and chemical coagulants) was investigated. In the next stage, the vulnerability of water quality to road construction activities was investigated by analyzing field monitoring data. In addition, two different approaches, involving information theory and gamma test theory, we…
