Description and objectives

The project entitled Dissipative Tie-rod Structural Monitoring (DTSM) focuses on the structural monitoring of existing masonry buildings reinforced with innovative instrumented local strengthening systems.

The building heritage in Italy and Europe is characterized by a high presence of historic masonry structures, often designed to resist only vertical loads, without particular consideration of seismic actions. Out-of-plane movements frequently cause collapses, especially in areas of high seismic risk, which are widespread across much of the territory.

Metal tie-rods are among the most common traditional local reinforcements used to prevent local failure mechanisms and ensure the structural integrity of the building. However, tie-rods have limitations, and there is often no information on their state of degradation, which can reduce the effectiveness of the intervention.
Recently, a dissipative end-anchor device has been developed for seismic energy dissipation, designed for controlled activation during high-intensity earthquakes.

This highlights the need for a monitoring system, including remote monitoring, for both new and existing seismic chains, with versatile solutions capable of adapting to different situations, being reliable, and cost-effective. Such a system could potentially improve the components of the LiCoRD CRD01O dissipation system on new or existing tie-rods.

The main objective of the project is the development and industrialization of a system for monitoring axial stress and temperature in seismic tie-rods for the local reinforcement of masonry buildings.
