From a GIS-based hybrid site condition map to an earthquake damage assessment in Iran: Methods and trends

摘要: Abstract From several decades ago, the average shear wave velocity for top 30 m (Vs30) has been proposed as one of important factors that reflects amplification behavior a site. Most seismic design standards such National Earthquake Hazards Reduction Program in United States and Standard No. 2800 Iran emphasize on use Vs30 measurements site classification according to soil type. As an step profound risk reduction earthquakes, effect study was conducted at nationwide scale. We followed indirect method produce map from geological topographical data. The outputs indicate hybrid better performance than single topography-based map. amplitude deduced geology maps then is used microzonation Tabriz city extent geographical distribution damage possible deterministic scenario (M=7) investigated through considering different fragility curves describe damaging ordinary building types city.
