Stress Ribbon Bridge in Nature Reserve


Length: 93,0 m
Width: 2,5 m


Blocklaminated glulam beams forms the main structure that works as a stress ribbon. At the abutments the structure is anchored into the ground.

Combining a stress ribbon structure, being mostly stressed by tensile forces, with timber as main construction material is very efficient, because of its low strength to weight ratio. Large-scale granite stone slabs form the decking. Natural stone is extremely durable and requires almost no maintenance. The abutments are designed as cantilevers out of reinforced concrete to allow a "smooth" tranfer ad deflection of the forces into the vertical components. A stress ribbon is characterised by it's narrow form. Towards the middle of the field minimum of slack span is required to provide an advantageous realtion of the horizontal forces.
