Bridge over L110 (object state)
A condition of an object at a particular time, reflecting the object's ability to fulfil it's requirements.

Object state
Summary
:
The designed measuring program comprised the recording of the rail longitudinal expansion and the rail longitudinal displacements in the rail fastening in defined measuring cross-sections. In addition, the relative displacements between the ends of the structure and abutments were measured and documented. The air, rail and structure temperatures were recorded and documented during the entire measurement period. By applying an accelerometer to the structure, any influence on the measurement data by construction site operations was detected and recorded. After the opening for traffic and commissioning in December 2012, additional sensors and measuring instruments were used to record the effects of vehicle-related loads such as vertical structural deformation and emergency braking attempts.
