Event description

Description

Structural Health Monitoring (SHM) is expected to play a predominant role in the management of the transport infrastructure nowadays mainly because much of the expected growth in traffic demand will have to be accommodated on existing infrastructure with widespread signs of deterioration.

Although instruments (such as resistance strain gauges and displacement transducers) have been installed on some structures, such devices only provide measurements at discrete points, and in most devices, have a limited working range.

Current SHM techniques require a dense network of such point-sensors, which is costly, if practicable. Furthermore, the technology of collecting and transferring the information from such devices cannot overcome problems of data congestion and network availability that arise during and following major accidents. Thus, current methods to access structural stability and the rate of deterioration can overlook structural problems or fail to detect them in time to permit effective and efficient intervention works. Over the past few years, a number of new and innovative systems have been developed to address these short comings. One of these, the SENSKIN system, will develop a sensing device capable of measuring strains in a surface area (as opposed to discrete points) as well as a reliable communication system that will ensure a robust and reliable delivery data between sensing nodes and base station. The SENSKIN (‘Sensing Skin’ for Monitoring-Based Maintenance of the Transport Infrastructure) H2020 project’s main features include:

- A micro-electronic, skin-like, sensor for monitoring transport infrastructure, with a spatial sensing of reversible (repeated) strains in the range of 0.012%,

- A delay (or disruption) tolerant communication system that will guarantee the delivery, availability and integrity of the sensor data even during hostile communication conditions.

- A Decision Support System (DSS) for proactive condition-based structural intervention under operating loads and intervention after extreme events.

The workshop will analyse the functional and operational requirements of the SENSKIN system based on the needs of bridge owners and operators as well as the methodology of the SENSKIN monitoring system. To facilitate and enhance knowledge exchange between practitioners in the field of SHM, a number of monitoring systems already being used (e.g. BRIMOS) as well as those currently being developed (e.g. AEROBI) will be presented. This will provide input into the panel discussion which will discuss among others, the latest trend in SHM, how to make SHM more prominent in bridge monitoring etc. Draft agenda.
