DOI: 10.1007/s10518-020-00851-x
Abstract: 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… read more here.

DOI: 10.1016/j.engstruct.2021.112420
Abstract: Abstract In past earthquakes, low-ductility steel concentrically braced frame (CBF) buildings have been observed to retain reserve capacity after brace fracture. The failure mechanisms and earthquake ground motion-sensitive characteristics of the reserve system of low-ductility… read more here.
