| Abstract: |
Timber Bridges has the prospects of being environmentally friendly and well adapted to future sustainability requirements. Norway has been a pioneer market for major timber bridges and has as per now around 250 timber bridges of this kind. This market experiences a major setback after Tretten Bridge collapsed in 2022. Tretten Bridge was a major timber truss bridge, and the paper will describe the comprehensive forensic engineering work performed in order to find and document the reason for this severe collapse. This work comprised advanced structural analyses and material tests, as well as evaluation of background material, collapsed specimens and witness observations. Many scenarios were investigated until the final reason for the collapse was revealed. |
