| Abstract: |
In Germany thousands of traffic bridges are built and have to replaced every year. The German government and the road construction authorities prefer standard structures and standard details for cost-saving reasons. Standard construction drawings for timber bridges have not been published yet in Germany. That’s why 39 standard construction drawings have been generated for timber bridges: To this day 11 details for standardisation have been developed to improve the durability of timber constructions; additional 28 drawings show part of the constructions more in detail. This presentation gives an overview of allstandard construction drawingsand it gives detailed information with reference to bridges in alpine countries. Together with thelifetimeand themaintenance costof a bridge (a field research project by the author), the drawings build the so called “magic triangle”. |
