Sažetak
One of the most important factors in mitigating seismic risk is identification of buildings which will result the weakest under the seismic shaking using the resonance approach. If the soil resonance frequency is close to those of buildings, soil-building resonance can occur which can cause severe structural damage or collapse of the building. It is also well known that resonance phenomena can have great influence on the spatial distribution of damage caused by destructive earthquakes. Dubrovnik-Neretva County is the region with the highest defined seismic hazard in Croatia. Therefore, in the scope of HOLISTIC Seismic and Wildfire Risks IPA project, estimation of dynamic parameters (fundamental period and damping coefficient, building response spectra) will be done for at least 30 strategic public buildings in the County, by performing measurements of building vibrations induced by ambient noise. Estimation of soil fundamental frequency will be done using the microtremor measurements in the free-field near the buildings. Based on these measurements, buildings with their natural frequencies close to the foundation soil resonance frequency will be identified as the ones that are in danger of the soil-building resonance during future earthquakes. In one of these buildings continuous instrumental monitoring will be performed by a broad-band sensor for the time period of at least six months in order to continuously monitor the variation of its dynamic parameters caused by environmental factors or earthquakes. Here we present preliminary results obtained in the measurement campaign of February-March 2015.
