Simplified analytical model for moment–axial force domain in the presence of shear in R.C. members externally strengthened with steel cages
2015
Equations for a hand calculation of moment–axial force domain in the presence of shear for R.C. beam/column externally strengthened with steel angles and strips are developed. The analytical derivation is made assuming, for axial load and flexure, the equivalent stress-block parameters for internal forces, considering the confinement effects induced in the concrete core by external cages both in the cases of strips or angles yielding. Limit states due to bond failure, concrete crushing and yielding of steel angles and strips in flexure and in shear, including moment-to-shear interaction, are considered. The proposed model gives results in a good agreement with available experimental data an…
Skolebygg : påvirkes elevens prestasjoner av skolebyggets utforming?
2011
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2011 Denne oppgaven tar sikte på å estimere hvordan ulike typer skolebygg påvirker elevers læringsutbytte. Utgangspunktet for arbeidet er problemstillingen: ”Hva er effekten av ulike typer skolebygg? Påvirker utformingen av læringsarenaen elevenes prestasjoner?” For å besvare denne problemstillingen velges en kvantitativ tilnærming. Ulike skoletyper som tradisjonelle klasseromsskoler og fleksible baseskoler blir identifisert gjennom et spørreskjema som sendes ut til de utvalgte skolene. Elevers læringsutbytte måles ved et karaktergjennomsnitt som inkluderer alle avsluttende karakterer på ungdomstrinnet, grunnskolepoeng. I ana…
Analyse av fremdrift med tilhørende avvik ved Prosjekt Lyngdal Ungdomsskole : en casestudie
2013
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2013 Kostnadsoverskridelser og forsinkelser er noe vi f ar stadig inntrykk av at intre er i store byggeprosjekter. Denne masteroppgaven undersø kte et pågående prosjekt og registrerte og analyserte alle avvik i forhold til fremdriften. Det ble ogs å undersø kt hvilke metoder som ble brukt for fremdriftstyring, og hvordan dette fungerte i praksis. Planlagt ferdigstillelse av Prosjekt Lyngdal Ungdomsskole var 01/05/2013, men revidert plan indikerer en overtakelse 31/05/2013. Det er fortsatt usikkert om bygget og uteomr ådet vil væ re komplett ferdigstilt til skolestart 2013, som var overordnet m ål. Det ble totalt funnet 150 av…
Etterspørselen etter leie av næringslokaler i Kristiansand : status i dag, videre utvikling og ulikheter i forskjellige områder av byen
2009
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2009 Hensikten med denne oppgaven er å kartlegge hvordan etterspørselen etter leie av næringseiendom er i Kristiansand. Jeg har samlet inn store mengder data om temaet, og datamaterialet brukes for å teste om det er mulig å fastslå noen sammenheng mellom tidligere utarbeidede teorier og mine data. Teoriene jeg har benyttet i oppgaven er DiPasquale & Wheatons (1996) modell for analyse av utleiemarkedet for næringseiendom og Rosens (1974) hedonistiske leiepristeori. I oppgaven har jeg utformet to hypoteser. Den første hypotesen sier at en bedrifts ønskede areal avhenger av antall ansatte. Forhåndsantakelsen til denne påstanden …
The BEYWATCH FP 7th European Scientific Project: dissemination and standardization activities, liaison with other projects
2012
The outcome of the BEYWATCH project has been spread in various ways, including different publication channels such as scientific journals and conferences, exhibitions, standardisation efforts and liaison with other relevant scientific projects. An overview of the dissemination activities is given in section 2, they include details about the Internet presence and the project presentations in workshops and conferences. Besides, some effort has been put into contribution to standardization. Contributions to standardization is found in section 3. Further, the project has set up liaisons to other European research projects. For each such activity, topics and forms of cooperation are described in…
Building integrated solar thermal design: assessment of performances of a low cost solar wall in a typical Italian building
2016
Abstract Present work deals with the topic of building integration of solar thermal collector (BIST) as a refurbishment measure. Such equipment, more than its main function as heating generator, plays a specific role as a building component (envelope finishes, thermal insulation layer, roof cover etc). Consequently, from a heat transfer point of view, an integrated component affects twice the global building balance: supporting the thermal plant (i.e. providing heat for final uses) and modifying the wall heat-transfer pattern (i.e. reducing thermal losses). In turn, the collector performance itself is influenced by the wall structure (back losses reduction). Present work proposes a method f…
Towards sustainable production of minerals and chemicals through seawater brine treatment using Eutectic freeze crystallization and Electrodialysis w…
2022
European policy encourages the adoption of sustainable systems that promote the efficient use and recovery of minerals and chemicals. In this respect, desalination brines do contain a dramatic amount of valuable minerals and can be valorized through appropriate treatments rather than releasing them into the environment. This paper proposes an innovative brine recovery system for obtaining high purity chemicals through the integration of Eutectic Freeze Crystallization (EFC) and Electrodialysis with Bipolar Membrane (EDBM) technologies. Two separate laboratory-scale experimental campaigns were carried out to validate the potential integration of the two processes. Mirabilite (Na2SO4∙10H2O) h…
Cold recycling of reclaimed asphalt pavements
2018
Pavement engineers have in front of them multiple challenges linked to addressing issues related to social development and society’s expanding needs. One of the most substantial of these issues is perhaps how to effectively rehabilitate and/ or maintain the existing road network while preserving and sustaining limited natural resources. The re-usage of existing pavement materials to reconstruct/ rehabilitate our future pavements is the solution that is now more and more selected by the different road administrations around the world. However, upon closer inspection, one can find many areas and details, not negligible issues, that are simply extensions of HMA technology (i.e. mix design proc…

En risikovurdering ved bruk av svalgang som rømningsvei : bruk av FDS til å undersøke brannsikkerheten ved fravikelser fra preaksepterte ytelser
2016
Masteroppgave bygg - Universitetet i Agder 2016 The purpose of this master thesis is to investigate the tenability limits on the egress path on an access balcony when not following all the given pre accepted solutions. The analysis construction deviates from some of the pre accepted solutions given for TEK10 to investigate if the fire safety level is satisfying. According to the standard NS 3901 Requirements for risk assessment of fire in construction works, a comparative qualitative analysis has been done by using FDS. The conditions that are analyzed is the time for critical temperature and heat radiation to occur where fire simulations in FDS has given the available safe egress time for …
