Bridge elevation

Colour by
60 positions per side over 2.7 km. Click a node to open it. Grey cells are positions with no device installed yet. A node is pinned to its cell by the side and position device attributes; chainage_m derives the position if that is not set. Cells with a dashed outline are placed by guesswork because neither was provisioned, so their position is not authoritative.

Passage peaks and dead load

Blue dots are the peak load of each detected passage — one dot per train, not a continuous signal. A step change in the general level is a structural signal worth investigating; a slow drift is usually temperature.

There is no dead-load or threshold line here: this node triggers on acceleration, not on load, so the trigger level is in mg and is shown in the tiles above rather than on a kN axis.

Peak load distribution

Load spectrum — rainflow cycles by range

Cycle counts are the trustworthy fatigue output. They are measured, not derived from an assumed stress conversion.

Cumulative damage

Detected passages

Select a passage to see its per-second shape. Passages captured before the node had the trace enabled, or uploaded after the node had already dropped them from memory, show no trace — that is reported rather than drawn as an empty one.
