Dual frames with removable dissipative members can be obtained by combining moment‐resisting frames with different bracing systems. These innovative systems can be very effective in developing the ”structural fuse” concept. On the one hand, they permit the replacement of the dissipative members damaged during an earthquake. If the moment‐resisting part is prevented from yielding, it can provide the restoring forces necessary to reduce drastically or even eliminate residual displacements, providing the structure with a re‐centring capability. The picture shows the setup of an experimental test on eccentrically braced frames (EBF) frames (see p. 73).
