摘要:

This study presents a new strategy to enhance the seismic performance of self-centering concentrically braced frames (SCCBFs). A hybrid strategy, which combines a SCCBF with a moment-resisting frame or buckling-restrained-braced frame, is first investigated, which show evident reduction in peak deformation demands. This benefit further inspires the design of multi-story pure SCCBFs with the enhanced post-yield stiffness ratio and/or energy dissipation factor directly. Incremental dynamic analyses indicates that the advanced SCCBFs achieve seismic peak deformation control comparable to that of the hybrid systems. Meanwhile, the advanced SCCBFs are nearly damage-free and fully recoverable after significant earthquakes, and thus represents a more favorable strategy from the seismic resilience perspective.
