Fragility Considerations in Highway Bridge Design

摘要: This report integrates statistical and analytical methods for the prediction of seismic performance highway transportation networks. For this purpose, an integrated framework involving structural engineering module multilayer simulation scheme is developed. a key component such spatially distributed systems. In analysis, it assumed that bridges are only components network system vulnerable to earthquake ground motion. Bridge damageability at various damage conditions expressed in form fragility curves associated with states minor, moderate, major collapse damage, mechanistically defined terms extent ductility rotation bridge columns bottom top. demonstrates application performance-based design bridges. On basis tools discussed here, acceptance criterion suggested can verify target level newly designed under prescribed hazard.
