Our services: Consultancy timber engineering and project supervision
Description:
The bridges are characterized by refined stepped timber beams, which have the largest cross section of just 60cm in the center field.
The glued laminated beam is not led to the end of the abutments but it ends about three meters in front of it, so the concrete slab transmits the forces into the abutment. The shear connectors are generated in this structure with a curved gutter, which are combinated with bonded steel brackets.
Moreover the concrete slab protects the timber beams from weathering. So the timber is only visible to the user when standing at the side of the bridge.
