Seismic Fragility Analysis of Monolithic Precast RC Frames Based on Joint-Level Hysteretic Parameter Identification
Monolithic precast reinforced concrete (RC) frames with cast-in-place joint cores and grouted-sleeve splices are increasingly adopted in seismic regions, yet connection degradation is not carried through to system-level fragility: existing studies take hinge properties from code tables or one test, or stop at the joint...
