Performance-based optimal design of self-centering friction damping brace systems between recentering capability and energy dissipation

This paper deals with a novel type of the friction damping brace systems and its development using slip resistance for seismic retrofitting of damaged structures. In the system, slotted bolt holes are placed on the shear faying surface with a view to dissipating a considerable amount of passive energy. Superelastic shape memory alloy (SMA) wire strands that enable self-centering mechanism and enhanced energy dissipation capacity are also installed between brace members. Self-centering friction damping braces (SFDBs) treated in this study have the desirable potential to efficiently reduce residual inter-story drifts in the braced frames during seismic events as compared to conventional passive damping systems. The SFDB system mechanism is described, and then its parametric study accounting for recentering capability and dissipative energy is carried out using numerical models that are calibrated with experimental data. Based upon the parametric investigation, this study suggests an optimal design methodology for establishing the smart self-centering bracing system.
