Seismic zonation and default suites of ground-motion records for time-history analysis in the South Island of New Zealand

The rise of performance-based earthquake engineering, in combination with the complexity associated selecting records for time-history analysis, demonstrates an expressed need localized default suites ground motion structural designers to use absence site-specific studies. In current research investigation, deaggregations probabilistic seismic hazard models (National Seismic Hazard Model, Canterbury and Kaik?ura Model) location-specific seismological characteristics expected motions were used define eight zonations accompanying suite profiles South Island New Zealand satisfy requirements design standard NZS1170.5 response-history analyses. Specific records, including 21 from recent Kaik?ura, Darfield, Christchurch earthquakes, then selected publicly-available databases presented as analyses This investigation encompasses hazards corresponding 500-year return periods, site classes C (shallow soils) D (deep soils), buildings fundamental periods between 0.4 2.0 seconds.
