Weidatalbrücke (RFB Göttingen) (object state)
A condition of an object at a particular time, reflecting the object's ability to fulfil it's requirements.
Properties
Element type
:
Object state
Summary
:
The results of the clamping force measurement indicate that the actual time-dependent deformations from creep and shrinkage are greater than assumed in the static calculation. Apparently the creep and shrinkage processes at the bridge are not yet complete. The measurement results of the inclinometer measurement and the final geodetic measurement from the construction phase were used as reference measurements. As a result, no significant shifts in the slope were found. The movement down the slope is approx. 2 mm over the entire measurement period. This also corresponds to the maximum value that was recorded at the geodetic measuring points and is therefore not critical.
