The JetPacs Project has been developed within the RELUIS 2005-08 project (Research Line 7: Technologies for base isolation and control of structures and infrastructures), involving partners from different Italian universities. The tests are carried out on a 1:1.5 scaled 2-storey, 1-bay, three-dimensional steel frame model. Six different passive and semi-active Energy Dissipating Bracing (EDB) systems are, alternatively, used during the tests. The complete experimental program is presented in a companion paper presented at the same Conference [Dolce et al., 2008]. The elasto-plastic EDB system adopted for the tests presented in this paper is based on the hysteretic properties of steel elements that provide additional horizontal strength, stiffness and energy dissipation capability, to limit the interstorey drifts of the structural system. The structural model is subjected to three different sets of natural and artificial earthquake records, compatible with the Italian seismic code response spectra for A, B and D soil types. The seismic intensity is progressively increased until the design performance criterion is achieved. The main objective of this experimental investigation is to evaluate the effectiveness of the EDB system in dissipating input energy and in reducing the seismic response of the structural model under moderate and strong earthquake. A further goal of this work is to verify the reliability of the simplified method used to design the mechanical characteristic of the devices. In this paper, the design of the elasto-plastic devices, as well as the preliminary non linear time history numerical simulations on the mock-up equipped with the hysteretic bracing system, are described.
