Abstract
Bidirectional shaking table tests are performed on standard hollow brick partitions, subjecting the partitions simultaneously to interstory relative displacements in their own plane and accelerations in the out of plane direction. Five couples of accelerograms are se-lected matching the target response spectrum provided by the U.S. code for nonstructural components, i.e. AC156, in order to investigate a wide range of seismic demand. Three dam-age states are considered and correlated to an engineering demand parameter, i.e. the inter-story drift ratio. The tested specimen exhibits significant damage for 0.3% interstory drift and extensive damage for displacement close to 1.0%. The tested partition exhibits a very large frequency, i.e. about 30 Hz, which is larger than the fundamental frequencies of typical struc-tures. A 1.93% damping ratio is assessed for the tested brick partition. It is also concluded that very simple models can adequately approximate the dynamic behavior of the tested non-structural components.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
