Monitoring Building Structural Health Using Smartphones And Ambient Vibrations

Patent Status

Patent Pending

Brief Description

This technology uses smartphones to monitor a building's structural health by recording ambient vibrations. The data is processed to determine structural parameters, establishing a baseline to identify changes that may indicate damage, and trigger inspections.

Suggested uses

• Large-scale structural health monitoring (SHM) applications

• Triggering inspections and further detailed investigations of buildings after a potential damaging event

• Monitoring a building's structural parameters on a regular basis to establish a baseline of normal environmental changes

Advantages

• Utilizes low-cost smartphone accelerometers and on-device data processing

• Enables the development of an automated technique to measure a building's fundamental frequencies

• Provides a robust and efficient tool for large-scale structural health monitoring
