Post-tensioned timber is a new form of seismic resisting timber construction which already has real building applications in New Zealand. The innovative high seismic performance system combines the use of precast concrete PRESSS technology and engineered wood products combining post-tensioning rods with large tim-ber members. These two elements provide elastic recentering to the structure when subjected to horizontal seismic excitation. Additional steel dissipation devices are often also placed in order to provide additional strength and dissipative capacity. The following paper describes the dynamic testing to be performed in the structural laboratory of the University of Basilicata, Potenza, Italy on a 3-storey post-tensioned timber struc-ture. The specimen is 2/3rd scale and made up of frames in both directions. Testing will be performed both with and without the addition of dissipative steel angles. This paper describes the testing set-up, the details of the frame, the steel angle devices and the shaking table testing program.

Abstract
Post-tensioned timber is a new form of seismic resisting timber construction which already has real building applications in New Zealand. The innovative high seismic performance system combines the use of precast concrete PRESSS technology and engineered wood products combining post-tensioning rods with large tim-ber members. These two elements provide elastic recentering to the structure when subjected to horizontal seismic excitation. Additional steel dissipation devices are often also placed in order to provide additional strength and dissipative capacity. The following paper describes the dynamic testing to be performed in the structural laboratory of the University of Basilicata, Potenza, Italy on a 3-storey post-tensioned timber struc-ture. The specimen is 2/3rd scale and made up of frames in both directions. Testing will be performed both with and without the addition of dissipative steel angles. This paper describes the testing set-up, the details of the frame, the steel angle devices and the shaking table testing program.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
