Digitizing Anchor Force Measurement: Reducing Effort and Keeping Information Up-to-Date

Anchor force measurement devices are often placed in hard-to-reach locations, and for assessment, there are usually only a few measurements available (typically one measurement every three years).
In the context of the research project SaRAS, we have demonstrated, together with Matthias Rebhan and Behensky, that these force measurement devices can be easily and swiftly digitized on-site (approximately one hour per anchor). The captured data is automatically transmitted to the cloud, stored in a structured manner, and can be accessed and downloaded via a mobile app or web browser.
By transferring measurements hourly (with battery life up to 15 years), we can also analyze the impact of environmental conditions on anchor force.
The advantages of this digital solution are manifold:

  • Real-Time Data: Anchor force data is accessible at any time through the app or web interface.
  • Warnings and Alerts: Critical conditions trigger immediate notifications via email or SMS.
  • Dense Measurement Series and Environmental Context: Trends and incidents can be better analyzed.
  • Temperature Recording: Influences from environmental conditions can be more precisely assessed.
  • Cost Savings: Depending on the structure, savings of 20% or more are possible.
  • Significant Reduction in Effort: Digital capture streamlines the process and saves time and resources.

In the SaRAS research project, we are working to develop innovative methods for assessing the condition of anchored constructions and implementing them in practice. Our collaboration involves partners such as the IBG, IGMS at TU Graz, AIT, burtscherconsulting, Behensky, recordIT, and the VÖBU. The project receives support from organizations including FFG, ASFiNAG, ÖBB, federal states, Keller Grundbau, ANP-Systems, and Swietelsky.
