Dynamic Testing in Support of the Seismic Assessment of a Century Old Masonry Building Complex

The vulnerability assessment of existing masonry buildings is a largely investigated research topic with some aspects still to be faced. In historic towns, are aggregated and together confined, their final appearance derived from interventions additions during lives in different times textures or construction materials. Demolitions reconstructions parts were frequent, the difficulty now understanding effectiveness mutual constraints. seismic case study 175-year-old building complex Udine (Italy) provides an opportunity use results ambient vibration tests face problem modelling aggregate for assessment. “Padiglione Lodi” was built 1847 extended renovated several afterwards. It mostly using URM limited reinforced concrete. consists main three wings (western, central eastern). inspections, experimental survey analysis available documentation used suitably calibrate Finite Element Model whole complex. Moreover, this allows singling out wing, as unit needs more careful investigation. Non-destructive dynamic testing then applied wing order further validate model improve knowledge interaction rest building. General remarks on effective application non-destructive conjunction other methods large complexes drawn.
