摘要: AbstractEarthquakes are rare natural catastrophes, causing severe impacts on society due to loss of lives, damage built facilities, and business interruptions. After a large earthquake (mainshock), many induced events (aftershocks) may be triggered cause additional or even collapse mainshock-damaged buildings. To reduce seismic hazard risk aftershocks extend the current performance-based engineering framework, effects performance structures should incorporated. Considering an extensive set real artificial mainshock-aftershocks sequences, vulnerability residential wood-frame houses in southwestern British Columbia, Canada, is examined analytically using incremental dynamic analysis. Subsequently, estimation conducted for four house types with different capacities. The analysis results indicate: (1) moderate (5–20%) maximum structural response e...
