Database Collection and Historical Earthquake Scenarios(I)

The main goals of the project are to collect civil infra-structure database and to simulate historical earthquake events using Taiwan Earthquake Loss Estimation System(TELES). The civil infra-structure database is classified into four categories: general building stocks, essential facilities, transportation systems and utility systems. In 2005, we had collected several database described in details later. In utility systems, we collected database of pipelines and facilities provided by Taipei Gas Company and Taipei Water Company. In transportation systems, we collected and calibrated database of main roads and bridges which belong to national freeway, provincial highway and county-level highway. We also tried to establish the analyzable road network which is composed of bridges, elevated highways and normal road segments. Cooperated with other project to assess seismic vulnerability of elementary and junior-high school buildings, we collected and integrated the school building database in TELES. Based on the various kinds of collected database, it is possible to use TELES to simulate historical earthquake scenarios and to calibrate various kinds of parameters in analysis models.
