This article introduces design rules to estimate the required strength and stiffness of dissipative bracing used for the seismic design or redesign of framed structures. These rules are calibrated by a parametric study on the inelastic response of SDOF systems under the action of scaled accelerograms recorded on soft soil. The proposed rules are sensitive to both the period and the seismic coefficient of the frame where the dissipative bracing is installed, and can be used for the preliminary design of dissipative bracing to impose a passive control on the ductility demand of framed structures.
