## Appendix B Determination of Range for Parameter \(\lambda\)
It can be argued that, because the analysis performed in the parametric study is purely linear, imposition of strength conditions derived from ductility considerations is inadequate. However, it must be kept in mind that current codes impose similar design conditions for frames with or without added damping systems [8] (clause 18.2.1.1). Thus, although linear behavior is a reasonable design target for the former, capacity criteria and seismic details ensuring ductility must still be adopted, to consider the possibility of non-linear behavior, given the uncertainty in seismic input [3]. \begin{table}
