Seismic design of multiple‐rocking systems: A gradient‐based optimization approach

Abstract: Self‐centering concentrically braced frames (SC‐CBFs) have shown many advantages towards structural damage‐free seismic behavior. These systems could be designed either with a single rocking section at the base or with multiple rocking sections along their height. Initial design methodologies for both cases have been proposed with an emphasis on the former case. These methods focused on simplicity of the design process and mostly relied on parametric studies. Thus, the obtained designs may violate some displac… Show more

“…29 Through the structural response analysis, the maximum interstory drift ratio (d maxdrift ) is mainly within [0.1‰, 2‰]. Furthermore, the structural deformation performance indicator (p drift ) is calculated using Equation (13). The equation indicates that, within the main interval of d maxdrift , if d maxdrift exceeds the drift limit, the indicator increases faster with d maxdrift such that the current design is less preferred.…”
