Abstract
This paper presents an experimental program based on the use of real-time hybrid simulation to verify the performance-based seismic design of a two story, four-bay steel moment resisting frame equipped with compressed elastomer dampers. The laboratory specimens, referred to as experimental substructures, are two individual compressed elastomer dampers, while the remaining part of the building is modelled as an analytical substructure. The proposed experimental technique enables an ensemble of ground motions to be applied to the building, resulting in various levels of damage, without the need to repair the experimental substructures since the damage will be within the analytical substructure. Statistical experimental response results incorporating the ground motion variability show that a steel moment resisting frame (MRF) with compressed elastomer dampers can be designed to perform better than a conventional steel special moment resisting frame (SMRF), even when the MRF with dampers is significantly lighter in weight than the conventional SMRF.
