Master's thesis in Civil and structural engineering (BYG508)

Analysing UHPFRC beams with the help of ANSYS

2018

Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2018 This Master thesis is about analysis of Ultra-high performance fibre reinforced concrete (UHPFRC) beams with the help of the Finite Element Analysis software ANSYS. The research question and the operational questions are: How can we analyse UHPFRC beams with the help of ANSYS? How does the built in concrete material model in ANSYS work? How can the concrete material model in ANSYS simulate behaviour of UHPFRC beams? The approach used to answer the questions is based on the hypothetico-deductive method. Hypotheses are built from the theoretical framework and tested in ANSYS. The results from the tests are …

Inneklima og energibruk ved bruk av balansert ventilasjon vs. hybrid ventilasjon i nybygg i massivtre : Skonnertveien Hageby

2018

Masteroppgave bygg BYG508 - Universitetet i Agder 2018 Most apartment buildings today are installed with mechanical balanced ventilation. A measure to reduce energy consumption and still satisfy the demand for heating is to apply hybrid ventilation. That includes using natural driving forces whilst reducing the use of mechanical ventilation. Furthermore, indoor climate in buildings is important because it has a major impact on human health, productivity and comfort. There is an increasing use of Cross-laminated timber (CLT) in Norway. However, there is little research on how CLT affects the indoor climate. The purpose of this master thesis is to investigate how balanced ventilation and hybr…

Use of BIM Technology and 3D-Modeling to Automate the Paperless Reinforcement Production

2018

Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2018 Although, Building Information Modeling has flourishing development for reinforced concrete, still there is a long way to achieve efficient performance throughout reinforcement supply chain. Statsbygg through the use of 3D reinforcement of digital construction project (Gol Traffic Station), desires to achieve a full paperless drawings and documentation project. There is also a strong ambition to standardizes those codes that are not mentioned in the official bending lists. This project has two-part and, follows these objectives: 1. Automate the production of reinforcement, production by direct export from…

Krysslaminert massivtre som bærende struktur i modulbaserte studentboliger : FEM analyse av modulbaserte studentboliger i krysslaminert massivtre

2021

Master's thesis in Civil and structural engineering (BYG508) This is a master’s thesis conducted at the University in Agder as the finishing work for the subject BYG508 and the master program in civil and structural engineering. This report seeks to examine some possibilities that exists with the use of Cross-laminated timber, CLT for modern student accommodation with the use of Finite element method, FEM software. With the increased interest in new building materials,it is important to examine the possibilities that lies within these materials and experiment and analyze to determine their usefulness. Based on the client’s wishes, the research question for this report was determined to be: …

Effektivisering av betongelementproduksjonen : Ved bruk av tegningsløs armering og prefabrikkert forskaling

2018

Masteroppgave bygg BYG508 - Universitetet i Agder 2018 Technology evolves exponentially, and technological aids follow the same course. Manufacturing methods in the construction industry are also constantly evolving, and a company that wishes to follow this development is Contiga. Contiga is the leading supplier of prefabricated concrete elements in Norway. For several years they have used the Lean methodology, and with this methodology mapped where in the manufacturing process there is room for improvement. Prefabrication has become more and more common in recent years, and innovative solutions and methods have also come. In the process of manufacturing the concrete elements, models are co…

A Bader’s topological approach for the investigation of the high pressure stability field of the Mg-perovskite phase

2014

The pressure-induced ringwoodite to Mg-perovskite and periclase post-spinel phase transition: a Bader’s topological analysis of the ab initio electro…

2011

In order to characterize the pressure-induced decomposition of ringwoodite (c-Mg2SiO4), the topological analysis of the electron density q(r), based upon the theory of atoms in molecules (AIM) developed by Bader in the framework of the catastrophe theory, has been performed. Calculations have been carried out by means of the ab initio CRYSTAL09 code at the HF/DFT level, using Hamiltonians based on the Becke- LYP scheme containing hybrid Hartree– Fock/density functional exchange–correlation terms. The equation of state at 0 K has been constructed for the three phases involved in the post-spinel phase transition (ringwoodite -> Mg-perovskite + periclase) occurring at the transition zone–lower…

Multi-doped Brookite-Prevalent TiO2 Photocatalyst with Enhanced Activity in the Visible Light

2018

© 2018 Springer Science+Business Media, LLC, part of Springer Nature Abstract: Enabling solar and/or visible light-driven photocatalysis is a crucial step to access innovative applications in environmental science and sustainable energy. Titanium dioxide is the most used photocatalyst because of its low cost and toxicity, however it is also limitedly active under visible light irradiation due to its wide band gap. Among its polymorphs, brookite holds promising optoelectronic properties for visible light photocatalysis, which have to the best of our knowledge been limitedly exploited. Here, a C,S,N-doped brookite-based TiO2has been prepared via a rapid one-pot sol–gel synthesis. Besides subs…
