Increasing traffic volumes require bridge monitoring in real time

The constant technical monitoring of bridge structures is gaining in significance due to elevated traffic volumes coupled with ever increasing axle load capacities. ASC accelerometers are helping to protect drivers, passengers and the structures in question.

Sensors enable early issue detection

The continuous collection, tracking and analysis of dynamic as well as static parameters is crucial to the early detection of structural deviations, emerging damage and critical capacity load burdens. Sensor based monitoring systems keep collecting reliable data to determine the overall condition of the bridge structure at any given moment.

Paired with digital algorithms and historical data, these real time parameters allow to produce long-term analyses to determine future repair and maintenance needs. Sensor based monitoring can identify deviations from the norm early on and help prevent deteriorating building conditions through targeted, proactive maintenance.

Should more rapid changes occur in a building’s structure, these will be captured in real time, too, leading to near instant interventions to establish the safety of the bridge and everyone on and around it.

Competent bridge monitoring around the globe

For example, to adequately capture and track vibrations and their impact, high-precision sensors are being attached directly to the bridge’s base and structure. ASC’s accelerometers are in use for this purpose at bridges worldwide. “They work absolutely reliably, with great precision and resist even extreme environmental conditions. We are looking forward to seeing the sensors perform in our future projects and to understanding their long-term stability,” Dr.-Ing. Christoph Tomann, an expert at German LPI Ingenieurgesellschaft, shares his experiences and expectations.

LPI Ingenieurgesellschaft mbH is a leading specialist in the field of building materials technology, damage diagnostics, structural repair and quality assurance. With more than 160 employees, it offers comprehensive services for the investigation and maintenance planning of existing structures. This also includes sensor-based monitoring of structures, especially in bridge construction.
