摘要

Substructure hybrid simulation has been the subject of numerous investigations in recent years. The simulation method allows for the assessment of the seismic performance of structures by representing critical components with physical specimens and the rest of the structure with numerical models. In this study the system level performance of a six-storey structure with telescoping self-centering energy dissipative (T-SCED) braces is validated through pseudo-dynamic (PsD) hybrid simulation. Fragility curves are derived for the T-SCED system. This paper presents the configuration of the hybrid simulation, the newly developed control software for PsD hybrid simulation, which can integrate generic hydraulic actuators into PsD hybrid simulation, and the seismic performance of a structure equipped with T-SCED braces. The experimental results show that the six-storey structure with T-SCED braces satisfies performance limits specified in ASCE 41.
