REAL-TIME EARTHQUAKE DAMAGE ESTIMATION METHOD BY SHAKING MODE 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 for appropriately estimating earthquake damage in accordance with an elevated bridge.;SOLUTION: The real-time earthquake damage estimation method for the elevated bridge includes a first seismometer 3 placed at the upper part of the elevated bridge 1 and a second seismometer 4 placed at the lower part of the elevated bridge 1. By subtracting a second displacement waveform output from the second seismometer 4 from a first displacement waveform output from the first seismometer 3, the displacement waveform of the shaking of the elevated bridge 1 itself is determined, thereby performing earthquake damage estimation for the elevated bridge 1 in real time.;COPYRIGHT: (C)2009,JPO&INPIT
