MEASUREMENT METHOD, MEASUREMENT DEVICE, MEASUREMENT SYSTEM, AND MEASUREMENT PROGRAM
To provide a measurement method capable of calculating a static response when a movable body moves through a structure, using processing with a comparatively small calculation amount.SOLUTION: A measurement method includes the steps of: generating first measurement data on the basis of observation data at an observation point of a structure; performing filter processing on the first measurement data to generate second measurement data; calculating a first flexure amount of the structure; performing filter processing on the first flexure amount to calculate a second flexure amount; approximating the second measurement data using a linear function of the second flexure amount to calculate a first order coefficient and a zero-th order coefficient; calculating a third flexure amount on the basis of the first order coefficient and zero-th order coefficient and the second flexure amount; calculating an offset on the basis of the zero-th order coefficient, the second flexure amount, and the third flexure amount; and calculating a static response by adding the offset and a product of the first order coefficient and the first flexure amount.SELECTED DRAWING: Figure 29
