On the other hand, brace axial capacity again had almost no effect on the normalized
energy dissipation. It has been suggested that when the energy is normalized to the equivalent
elastic-linear-hardening hysteretic shape shown in the inset of Figure 7b, that a good target for
self-centering systems is 0.25 (e.g. Seo and Sause 2005) to limit peak drifts. As shown in Figure
7b, the SC-BRB configurations with little or no BRB component (α sc →∞) have an energy
dissipation ratio approximately equal to 0.25 and thus could be considered a valid brace design.
