Seismic Fragility Curves of Steel Frames Equipped with Easily Repairable Dissipative Devices
This paper provides insight into a probabilistic demand analysis of a steel-concrete structures equipped with novel dissipative components. DISSIPABLE components were studied in the framework of a European Research Fund for Coal and Steel (RFCS) project, funded to test largescale structures in which the dissipation is concentrated in specifically designed elements that act like a fuse and can easily be replaced after a seismic event. Incremental Dynamic Analyses (IDAs) were performed to investigate the influence of equipping steel frames with two different dissipative seismic devices, namely the Dissipative Replaceable Beam Splice (DRBeS) and the Dissipative Replaceable Link Frame (DRLF). The benchmark models were calibrated on the results of laboratory full-scale tests, carried out in the project framework. In addition, the DISSIPABLE frame behaviour was compared with a state-of-the-art moment-resisting frame, designed according to the capacity design philosophy. Probabilistic demand models were developed, and seismic fragility curves were then derived to compare the behaviour of the analysed structural systems.
