Ancient Building Tilt & Vibration Monitoring

Ancient building tilt & vibration monitoring

Wooden columns, mortise-and-tenon joints and rammed-earth foundations deform slowly over centuries, and can then move abruptly when an earthquake or typhoon arrives. Compact VTS sensors monitor the structure continuously, with minimal intervention to the historic fabric.

Why heritage structures deserve modern sensing

Heritage timber structures fail differently from modern buildings: joints loosen, columns lean almost imperceptibly, and the structure's natural frequency shifts as connections degrade. Conservators need evidence rather than impressions — continuous tilt and vibration data that documents the building's condition and helps justify intervention before damage progresses further.

Typical use cases

One sensor, four conservation questions

Column & frame lean — 0.0005° resolution documents seasonal and long-term lean of columns and frames, distinguishing normal breathing from progressive deformation.
Vibration & seismic response — the built-in FFT engine analyses 0.5–20 Hz structural response — from heavy traffic outside the wall to real seismic events.
Foundation & ground movement — long-term zero-drift trends can indicate soil settlement under stone plinths, a common cause of problems in ancient buildings.
Restoration verification — before-and-after datasets quantify what a restoration changed, supporting both the building owner and the contractor.
