Abstract

 Prompt provision of structural damage estimation information is strongly demanded at the time of an earthquake, especially at the stage of little information immediately after the earthquake. Currently, there is a method to estimate the degree of damage to highway bridges using the “Structural Damage Estimation Flow” as a method to know the general situation of earthquake damage immediately after the disaster. However, compared with the actual damage degree in The 2016 Kumamoto Earthquake, it was found that the damage level according to the “Structural Damage Estimation Flow” does not match the actual damage situation.  In this paper, I examined the cause and revised where the damage is under-estimated by the flow such that the actual degree of damage is higher than the estimated degree of damage according to the “Structural Damage Estimation Flow”.
