Structural monitoring and integrity of masonry buildings in Slovenia

It is estimated that older reinforced buildings represent almost 50% of the total number of existing buildings in Slovenia. It is further estimated that 1/3 of the population of Slovenia lives in areas where the PGA is 0.2 g or more. Seismic resistance of such buildings in general is not sufficient and appropriate measures should be implemented. It is recommended that these are designed incorporating the findings of structural monitoring based on which useful information can be obtained. Structural monitoring aims to monitor the possible advancement of existing or formation of new damage due to various reasons, while strengthening measures aim to ensure structural integrity and adequate level of seismic resistance of building. The article describes the current practice in this field in Slovenia through practical examples. Additionally, suggestions that could help improve the current approach such as combining the global calculation model with local failure mechanisms and combining the activities of monitoring, investigations of structure and assessing seismic resistance are given. Usage of emerging technologies that are non-invasive both in monitoring, as well as investigation of structure is encouraged. It is recommended that reversible strengthening measures especially in the case of heritage buildings are used.
