국내 해안시설 영역의 지진피해 예측을 위한 HAZUS 적용성 고찰

HAZUS-MH Earthquake, a GIS-based software package developed by FEMA and NIBS for earthquake loss estimation, was used as part of the preparations of the future seismic events at a coastal facility area in Korea. To reliably characterize the target facility area, many geotechnical and geophysical data were synthesized from the existing site investigation reports in the study area and buildings and facilities were categorized by analyzing their material and structural characteristics. Moreover, fragility curves of a main facility were derived based on the numerical modeling and were incorporated into the database in HAZUS. The results estimated in the study area using HAZUS-MH Earthquake showed various damage and loss potentials depending on site conditions and structural categories. This case study verified the usefulness of the HAZUS for estimating earthquake loss in coastal facility areas.
