The wide range in frequency contents of possible strong ground motions can have impact on the seismic response, vulnerability and limit state criteria definitions of RC high-rise wall structures. Motivated by the pressing need to derive more accurate fragility relations for use in seismic risk assessment and mitigation of such structures, a methodology is proposed to obtain reliable, Seismic Scenario-Structure-Based (SSSB) definitions of limit state criteria. A 30-storey wall building, located in a multi-seismic scenario study region, is utilized to illustrate the methodology. The building is designed following modern seismic code provisions and then modelled using nonlinear fibre-based approach. Uncertainty in ground motions is accounted for by the selection of forty real earthquake records representing two seismic scenarios. Seismic scenario-based building local response at increasing earthquake intensities is mapped using Multi-Record Incremental Dynamic Analyses (MRIDAs) with an improved scalar Intensity Measure (IM). Net Inter-Storey Drift (NISD) is selected as a global Damage Measure (DM) based on a parametric study involving seven buildings ranging from 20-50 stories. This DM is used to link local damage events, including shear, in the sample building to global response under different seismic scenarios. The study concludes by proposing SSSB limit state criteria and fragility relations for the sample building. The proposed methodology, limit state criteria and fragility relations is suitable for comparable RC high-rise wall buildings exposed to multiple-scenario earthquakes.
