BRIDGE DISPLACEMENT AMOUNT CALCULATION DEVICE, BRIDGE DISPLACEMENT AMOUNT MEASUREMENT DEVICE, BRIDGE DISPLACEMENT AMOUNT CALCULATION METHOD, BRIDGE DISPLACEMENT AMOUNT MEASUREMENT METHOD, AND PROGRAM
To calculate a bridge displacement amount without specifying an analysis period.SOLUTION: A bridge displacement amount calculation device includes a DC component removal unit, a high pass filter unit, a first integration unit, and a second integration unit. The DC component removal unit outputs DC removal acceleration data. The high pass filter unit uses an inverse number of the time taken for a vehicle to pass between skeletons of a bridge as a cutoff frequency. The first integration unit integrates the input data. The second integration unit integrates the input data and outputs displacement amount data. The high pass filter unit inputs DC removal acceleration data, the first integration unit inputs the output of the high pass filter unit, and the second integration unit inputs the output of the first integration unit. Alternatively, the first integration unit inputs the DC removal acceleration data, the high pass filter unit inputs the output of the first integration unit, and the second integration unit inputs the output of the high pass filter unit. A bridge displacement amount measurement device includes an acceleration sensor, a cutoff frequency determination unit, and the bridge displacement amount calculation device.SELECTED DRAWING: Figure 1
