Seismic Fragility Curves of Steel Frames Equipped with Easily Repairable Dissipative Devices

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