Abstract
A measurement method includes: an acceleration data acquisition step of acquiring acceleration data output from an accelerometer that observes an observation point of a structure when a moving body moves on the structure; a speed vibration component calculation step of calculating a first speed vibration component by performing integration processing and filter processing on an acceleration based on the acceleration data; and a displacement amplitude estimation step of estimating a displacement amplitude of the structure when the moving body moves on the structure based on an amplitude of the first speed vibration component and a conversion function calculated based on an approximate expression of deflection of the structure and environmental information including a dimension of the moving body, a dimension of the structure, and a position of the observation point, which are created in advance.
