| Abstract: |
Inadequate earthquake resistance of existing bridges has been identified over the last years as a global engineering challenge, both for countries of high and of moderate seismicity, such as Switzerland. In this article the project of the seismic isolation of the Wysseflue-viaduct B28 at the Swiss national route A8 is presented as a case study of the suitability of this method for the protection of life and invested value of bridges with typical for Switzerland seismic deficiencies. Seismic isolation with low damping elastomeric bearings has been chosen as the technically most suitable and cost-efficient retrofit strategy, as retrofit costs do not exceed 3% of the estimated value of the structure. |
