REAL-TIME EARTHQUAKE DAMAGE ESTIMATION METHOD BY SHAKING OF ELEVATED BRIDGE AND ITS APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a real-time earthquake damage estimation method by the shaking of an elevated bridge and its apparatus in simple configuration for appropriately estimating earthquake damage in accordance with the elevated bridge. SOLUTION: The real-time earthquake damage estimation method by the shaking of the elevated bridge includes a seismometer 3 placed at the upper part of the elevated bridge 1 and performs earthquake damage estimation by the shaking of the elevated bridge 1 in real time on the basis of information from the seismometer 3. The information from the seismometer 3 is a peak frequency of a bridge-axial-orthogonal direction/bridge-axial direction spectrum ratio. COPYRIGHT: (C)2009,JPO&INPIT
