Assessment and evaluation of the structural condition and structural repair of the Norderelbe railway bridge

The structural condition of the centennial Norderelbe railway bridge in Hamburg and the structural safety have been assessed and evaluated. Various non-destructive inspection methods and extensive structural monitoring measures have been applied to aid the structural evaluation and recalculation, revealing some isolated structural deficits of selected members. The contribution describes the steps towards a safe operation of the structure until the prospective commissioning of a replacement bridge which imply the mentioned inspection and monitoring measures as well as structural repairs and the establishment of a continuous structural monitoring. The extensive structural monitoring revealed insights into the structural behaviour of the tied-arch bridge which are outlined as well.
