Bridges, floors, platforms, and fixed structures

Structural Evaluation

Measure structural response under real operating conditions.

Multi-location monitoring connects measured response to documented locations, traffic, equipment activity, transient events, and environmental context.

VibeTech provides multi-location vibration monitoring for bridges, floors, platforms, supports, and other structures. Studies can capture ambient response, traffic or equipment-related vibration, transient events, and changes occurring throughout an operational period.

The measurement infrastructure, documented sensor configuration, processed results, and raw waveform data can be supplied to qualified professionals for advanced analysis, including operational modal analysis where acquisition and timing requirements are met, analytical-model correlation, load-rating support, and long-term structural-health monitoring.

Monitoring arrangement

Documented sensor positions create an auditable relationship between each waveform and its physical bridge location, enabling meaningful comparison of supports, spans, and measurement directions.

Operational event

A time-history event window isolates structural response associated with a defined period of activity, allowing comparison of onset, peak response, and decay instead of relying on one overall value.

Location comparison

Time-aligned waveforms expose differences in amplitude, arrival, and decay across documented bridge locations, providing focused evidence for deeper structural review.

Mode 01

Operational Response Screening

Documents vibration behavior under normal environmental and operating conditions.

Mode 02

Engineer-Directed Measurement Support

Collects data according to a monitoring plan developed by a licensed engineer or structural specialist.

What the evidence can support

01

Document ambient and operational response

02

Compare measured behavior across structural locations

03

Characterize traffic or equipment-related events

04

Supply evidence for model correlation

05

Support long-term monitoring programs

06

Provide data for qualified professional review

Deliverable standard

Every reported result remains linked to the sensor identity, documented location, collection time, measurement configuration, operating context, and underlying waveform data.

Interpretation note

Measured evidence, stated responsibly.

Operational response screening is not a bridge inspection, structural load rating, proof-load test, modal certification, or determination of structural safety. Those conclusions require evaluation by an appropriately qualified professional.
