| Abstract: |
While upgrading Highway 27 in Sweden, a 47,4 m long arch bridge consisting of glulam was built. Due to architectural reasons, the aches were not allowed to be connected to each other above slab level. The moment transmitting joint between the vertical beam hanger and transverse girder results in U-shaped connections between the arches. A 13,9 m spacing of the arches made the design of this structural part challenging. Stability of the arches was especially considered, regarding both in and out of plane buckling due to vertical and horizontal loads. Dynamic factors for the wind load were calculated using a single mode principal. A stress-laminated timber slab made of glulam beams was used as the bridge slab. This glulam - steel hybrid structure consists of approximately 230 000 kg of untreated glulam and approximately 100 000 kg of steel. |
