Concrete Trough Bridges on the Iron Ore Railway Line (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

:

In tests, it was found that the bridge could withstand 6 million load cycles at 360 kN without any signs of distress. Only hairline concrete cracks could be seen. It could be concluded that the codes were quite conservative regarding fatigue.

Performance indicator

:

Displacement, Traffic information via WIM/BWIM, Load bearing capacity, Full scale laboratory test

"Full scale laboratory test" is not in the list (Deformation, Displacement, Traffic information via WIM/BWIM, Dynamic response (acceleration/damping/frequencies), Material mechanical properties, Chemical properties, Electrical properties, Load bearing capacity, Spatial properties (concrete cover/duct voids), Other actions (wind/temperature/earthquake), ...) of allowed values for the "Performance indicator" property.
