Methodology of Seismic Hazard Analysis and Damage Assessment

Since Taiwan locates at seismic active region, seismic hazard mitigation
is always one of the most important parts in natural hazard mitigation
plans. To have effective seismic hazard mitigation plans needs
cooperation of experts in many fields. In order to accelerate the progress
in seismic loss estimation and hazard mitigation, Haz-Taiwan adopts the
methodology from HAZUS, which is developed by the scientists and
engineers in the United States. However, Taiwan has its special
construction environment and quality, seismic design codes, social and
economic activities, etc., not only the inventory data but also the
analytical models and the associated parameters need to be collected and
calibrated.
This joint project investigates methodology of seismic hazard analysis
and structural damage assessment from earthquake engineering
viewpoint. The main objective is to provide technical support, to develop
analytical models, and to calibrate associated parameters in Haz-Taiwan
program. The research topics include estimation of ground motion
intensities due to scenario earthquakes, estimation of permanent ground
deformation due to soil-liquefaction, evaluation of site-dependent seismic
demand of buildings, evaluation of capacity and fragility curves in damage
assessment of reinforced concrete buildings and multi-span continuous
bridges, and so on.
