| Abstract: |
Historic and archaeological sites are often subjected to harmful environmental as well as human factors. Covering these sites with protective structures or shelters does not always render the desired result, since the authentic character of the site may be impaired. By building walkable covers above the area, social interest in historic remains can be promoted, as visitors can observe them from above without intruding activity or influence the ambient conditions. In addition, these walkways can be equipped with lateral cables to shift foils above the site, whenever visits are prevented by the weather. Three typologies of adapted footbridges are introduced. For each type, requirements of strength, stability, human induced vibration and effects of wind, including vortex are being verified. In some cases vortex shedding seems the most critical condition, albeit simple adequate systems can be installed for mitigation. |
