Danish breakthrough for approval of GRP bridges

Recent research on partial coefficients (safety factors) for Fiberline's structural profiles is now leading to work on road standards that will make it significantly easier to design and build GRP bridges with GRP.
Despite the existence of more than 3,000 composite bridges incorporating Fiberline materials in the Netherlands, Germany, UK and elsewhere it has been difficult to design new GRP bridges for Denmark as no Danish partial coefficients have been formulated. All this changed in 2015 when consulting engineer Carsten Plum and Professor John Dalsgaard of Aalborg University completed their work on the safety factors required by Danish authorities and contractors.
This milestone opens the way for the formulation of Danish road standards that will make building with GRP composite just as straightforward as using conventional materials like steel and concrete. Erik Stoklund Larsen of the Danish Road Directorate takes up the story:
"The Danish Road Directorate has followed with considerable interest Fiberline's determined efforts to remove such obstacles as may exist in Denmark to the use of GRP composite for a range of purposes, particularly structural applications. The establishment of an EN norm/partial coefficient for the company's structural profiles was a major step in the right direction, and this will also simplify the upcoming work of elaborating road standards and design guidelines for GRP bridges."
At Fiberline too, hopes are high with regard to the results of the work on the Danish partial coefficients. Jan Pasfall, Fiberline's Vice President for Structural Profiles explains:
"Through this work we have created a breakthrough for the use in Denmark of smarter materials for applications such as building bridges. Our profiles combine qualities like high strength with light weight and outstanding durability, and it is precisely these types of qualities that tomorrow's energy-efficient society needs."
The Danish partial coefficients which lean on the ongoing work with Eurocode-standards, and the upcoming road standard work will add to the data for Fiberline's structural profiles, which are already well documented and have already been granted German stamp of approval (Allgemeine Bauzulassung). Furthermore, we expect to be able to add CE marking before the end of the year.
