Monitoring of buildings - especially of bridges- gets more and more important. The reasons for this arethe increase of the heavy goods traffic, of air pollutionand in precipitations, de-icing salts and the fact thatprices for traditional maintenance and repairs are goingup.The bridge Schiessbergstrasse in Leverkusen represents anew generation of building structures having a perfectsolution for this kind of problems: prestressing with"intelligent tendons", monitoring of the stress strainbehaviour of the concrete, chemical sensors, and - in thecase of the bridge Schiessbergstrasse additonally areinforcement with epoxy coating and foil sealing withpolyurethane of the bridge deck.
