Database of Near-Fault Highway Bridge Damage in Recent Taiwan Earthquakes and Preliminary Fragility Investigation

Database of Near-Fault Highway Bridge Damage in Recent Taiwan Earthquakes and Preliminary Fragility Investigation

In this investigation, a database of near-fault highway bridges involved in the 1999 Chi- Chi earthquake and 2018 Hualien earthquake is established. Totals of 151 and 24 bridges, respectively, all within the vicinity of the ruptured faults and with or without damage, are included. The structural attributes, strong motion intensity, distance to the fault, and offset experienced (if any) of each bridge are either well calibrated or carefully determined. Furthermore, we classify and record the damage states and modes for the 16 and 5 damaged bridges after the Chi-Chi and Hualien earthquakes, respectively. This database is employed to predict the damage of each bridge using the Thighway software developed by NCREE for the damage and loss estimation of highway bridges. A comparison of the prediction and actual damage is made.
