Monitoring Instruments for Structural Health and Related Applications

Structural Health Monitoring allows owners of structures such as bridges and buildings to:

·Improve decision making
·Manage risks
·Increase safety
·Increase productivity
·Optimize designs
·Reduce costs

Structural Health Monitoring (SHM) – An Overview

  • Many asset owners and their engineering design firms assess and manage the health of their structures to prioritize maintenance/rehabilitation and replacement of aging structures. Historically, visual inspections have been the main form of assessment of these structures.
  • SHM Systems can be used to complement visual inspections by providing real-time data of structural parameters. Over time, changes in these parameters can give indications of the health of the structure and allow the owner to prioritize which assets need urgent attention. Action plans can be designed and implemented based upon collected data.
  • SHM can be used both on aging and new structures alike and many new structures are being designed with SHM specified.

Benefits of Monitoring Systems

  • By deploying instruments on structures, a reliable and accurate understanding of their structural safety and integrity can be achieved. Ideally, SHM is implemented prior to concerns with the assets’ health, to allow for the collection of baseline data. In the case of aging structures, monitoring trends over time is critical.
  • Asset managers are given the ability to compare the acquired instrumentation data with the assumptions made in design and can make informed decisions. They can then make conclusions regarding the health of the structures as well as prioritize funds for maintenance/rehabilitation or replacement.
  • Monitoring instruments provide insight to key areas of concern, such as:
    • Load and stress
    • Tilt
    • Displacement
    • Acceleration/vibration

The Path to Success – Core Structural Health Monitoring Components

  • Instrumentation type and data acquisition and collection methods should be selected to suit site-specific conditions and stability concerns.
  • Instrumentation installations should be designed to answer site-specific concerns in the structure including the structural parameters to monitor and the location to install the sensor.
  • A variety of data acquisition options are available to meet site-specific needs. These can range from manual to fully automated systems.
  • RST’s Instrumentation Engineers and Specialists can aid in selecting the right solutions for your site conditions.
