AB This research develops a new low-cost energy dissipation system, capable of beingimplemented in residential structures in developing countries with high seismic activity, in whichthe current solutions are not economically viable. These residential structures are entirely made ofprecast concrete elements (foundations, walls, and slabs). A solution is developed that consists of anew connection between a precast foundation and a structural wall, which is capable of dissipatingalmost all the seismic energy, and therfore protecting the rest of the building from structural damage.To validate the solution, a testing campaign is carried out, including a first set of “pushover” tests onisolated structural walls, a second set of “pushover” tests on structural frames, and a final set of seismictests on a real-scale three-storey building. For the first and second set of tests, ductility is analyzedin accordance with ACI 374.2R-13, while for the third one, the dynamic response to a referenceearthquake is evaluated. The results reveal that the solution developed shows great ductility and norelevant damage is observed in the rest of the building, except in the low-cost energy dissipationsystem. Once an earthquake has finished, a precast building implemented with this low-cost energydissipation system is capable of showing a structural performance level of “immediate occupancy”according to ACI 374.2R-13.
