Recent devastating earthquakes showed the high vulnerability of existing infilled reinforced concrete (RC) buildings. Thus, experimental tests are crucial to investigate their seismic performance. To this end, a full-scale two storey infilled reinforced concrete frame, representative of a portion of an existing building damaged by the 2009 L’Aquila earthquake, was reproduced in a laboratory environment. The prototype frame was tested under pseudo-dynamic (PSD) loads. In order to apply to the prototype frame realistic seismic actions, a simple substructuring criterion is followed. The experimental results were used to validate a FEM model, then used to assess the reliability of applied PSD testing protocols. The experimental tests were capable of reproducing the observed earthquake damage on infills and RC structure.

Abstract
Recent devastating earthquakes showed the high vulnerability of existing infilled reinforced concrete (RC) buildings. Thus, experimental tests are crucial to investigate their seismic performance. To this end, a full-scale two storey infilled reinforced concrete frame, representative of a portion of an existing building damaged by the 2009 L’Aquila earthquake, was reproduced in a laboratory environment. The prototype frame was tested under pseudo-dynamic (PSD) loads. In order to apply to the prototype frame realistic seismic actions, a simple substructuring criterion is followed. The experimental results were used to validate a FEM model, then used to assess the reliability of applied PSD testing protocols. The experimental tests were capable of reproducing the observed earthquake damage on infills and RC structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
