˗ Doel: Milieuwinst t.o.v. andere materialen inzichtelijk maken en delen;

˗ Vergelijk: Ontwerp biocomposiet vergelijken met staal, beton, glasvezel en (accoya)hout;

˗ Producten: 1 x DO in Vlas en 4x VO-constructieberekeningen met alternatieve materialen,

hoeveelhedenlijsten, ramingen en eindrapportage

˗ Resultaat: Eindrapportage beschikbaar rond week 50 2019

˗ Hoe?: Circulairiteitsscan (Circulair Design Tool) – vlasvezelcomposiet vs. Traditionele

De +Circular Design tool helpt om de circulariteit van een ontwerp inzichtelijke te

maken door bepaling van:

- CO2-uitstoot

- MilieuKostenIndicator (MKI)

- Material Circularity Indicator (MCI)

˗ Sanky diagram -> geeft de herkomst en de herbruikbaarheid van de materialen

(los of samengesteld in componenten) in het ontwerp visueel weer

- Aangevuld met een kostencalculatie

MKI – Milieu Kosten Indicator

12

• MKI is een methode om de milieueffecten (13

stuks) te berekenen van een materiaal, een

bouwwerk -of methode. De gehele

levenscyclus komt daarbij in beeld, vanaf de

winning tot en met de sloop.

• MKI wordt berekend met behulp van DuboCalc

en resulteert in een fictief bedrag. Hoe hoger

het bedrag hoe grotere milieubelasting.

- Randelementen en leuning buiten beschouwing

- Invloed gewicht varianten brugdek op onderbouw op kwalitatief niveau beschouwd;

- Levensduur van de brug van 100 jaar, zonder vervanging van de hoofddraagconstructie

- Berekening CO2-uitstoot en MKI uitsluitend getallen gebruikt uit de Nationale Milieu

Database (NMD) conform bepalingsmethoden voor GWW-werken;

Strain state vs yield strain

35

• “Working” strain state of the bridge in comparison with

the yield strains defined during the experimental test

material session

• Already proved to be beneficial for decision making

with respect to actions after a calculation mistake in

the produced shape of the fixed-span

• Draw strain regression lines

• Calculation of the curvature
