The JetPacs Project is developed within the RELUIS 2005-08 project (Research Line 7), involving several partners from different Italian Universities. The tests are going to be carried out on a 2:3 scaled structural model derived from a 2-storey, 1-bay, three-dimensional steel frame, prototype building. Six different passive and semi-active Energy Dissipating Bracing (EDB) systems will be, alternatively, used during the tests. The complete experimental program is described in a companion paper presented at the same Conference. In this paper, the design objectives, preliminary numerical simulation analyses, experimental program and set up of the tests on the mock-up equipped with the visco-recentring EDB system are outlined. Each visco-recentring device is obtained by coupling a velocity-dependent energy-dissipating device based on visco-fluids with a recentring device based on Shape Memory Alloy (SMA) NiTi wires. The energy dissipating devices are mounted on the top of a stiff V-inverted steel brace. During the tests, the structural model will be subjected to three different sets of natural earthquakes, compatible with the response spectra of the Italian seismic code for soil type A, B and D. The seismic intensity will be progressively increased, up to the attainment of the performance objective adopted in the design. The main objective of this experimental investigation is to evaluate the effects of the viscous and recentring components of the EDB system on the seismic response of the structure and to verify the effectiveness of the simplified method used to design the mechanical characteristic of the device.
