16 NTNU principal research themes Bridge fjord crossing solutions Sustainable design and implementation of roads

17 Fjord crossings Misson statement: Enable design of long span fjord crossing structures Model the environmental loading on the fjord crossing structures Establish computational tools to simulate dynamic reponse Establish design criteria for safety and comfort Establish service life criteria and prediction tools

18 Expected research results Obtain data for design and engineering of bridge concepts (reference solutions to be security cleared) Realistic numeric models that inckudes all significant parameters Loads Load effects Structural properties (air, fluids, earth) PhD candidates with sepcific competences Identify further research needs Kick-off meeting E39 Fjord crossings

19 Research set up Focus on PhD and Postdoc projects with complimentary research and support from NPRA staff Combine full scale measurements, laboratory experiments and analytical/numerical models Discussions for need for «Met ocean» data with people measuring and simulating environmental loads Kick-off meeting E39 Fjord crossings

20 Fjord crossing related Ph.d.and postdoc Wind loads and responses Wave loads and effects Ship collisions with floating aand submerged bridges Explosions and fires og brann in submerged bridges Foundations Parametric excitations Dynamic responce of bridges Characteristic envrinmental loads and effects for design engineering CFD response analysis (air and fluid dynamics) Material properties of concrete (durability)

21 Financing of fjord crossing research E39 Statens vegvesen: E39 SVV Region vest: SVV general ph.d budget: NTNU: Forskningsrådet + SVV Forskningsrådet + næring 9 candidates 2 candidates 1 candidates 2 candidates 1 candidates 4 candidates Total: 19 candidates

22 Ship collisions Overflatefartøy Flytebru (pontong, brubjelke) Hengebru med flytende tårn U-båter Neddykket flytende tunnel Forankringssystemer Synkende skip mot neddykket flytende tunnel Lokal og global lastvirkning Skipets bevegelse relativt til brukonstruksjonen Analyser for et utvalg av ulike skipstyper og hastigheter

23 Dynamic response av floating bridges Ph.d.-prosjekt finansiert av Statens vegvesen utenom Fergefri E39 Analytisk/numerisk modellering Målinger Bergsøysundbrua Vindfelt (mulig inhomogenitet, korrelasjon langs brua) Bølgemåling langs brua (kortkammet sjø) Korrelasjon vind og bølger Respons av brua

24 Roads and Transportation Mission statement: Develop knowledge for sustainable design, construction, operation, and maintenance of E39 Develop safer solutions for road lifecycle Develop lower energy solutions for road lifecycle Develop environmentally friendly solutions for road lifecycle

25 Norway: Carbon Neutral by 2050?

26

27 Goals National Transport Plan (NTP) Emissions form construction of transport infrastructure should be reduced by 40% within 2030 Emission from maintenance and operation of transport infrastructure should be reduced by 50% within 2030 In 2050, the transport sector should be nearly emission-free (Carbon neutral)
