Hochstraße Barkauer Kreuz in Kiel - Nachrechnung und Instandsetzung einer anspruchsvollen Spannbetonbrücke

Bridge across the Barkauer Crossing in Kiel - Recalculation and rehabilitation of a demanding prestressed concrete bridge

The bridge across the Barkauer crossing was built in 19970/71 as a prestressed concrete bridge with a wide T-beam cross section. The bridge has seven spans with span widths up to 33.15m and it is extremely curved in the ground section. The recalculation of the bridge on the levels 1 and 2 according to the German recalculation regulations [1] showed good results for most of the parts of the bridge. Deficits were found only in the axes B,C and D. Therefore a recalculation on level 4 was done, based on a FE-calculation and the proof for bridge class 60 was obtained. For a safe long time use a rehabilitation was necessary.
