This paper presents calculation method for displacement from acceleration record in easy way. Using recursive digital filter is good for easy calculation, so simple formula is proposed, which is combined of integration and low-cut filter. Shaking table test is carried out in order to investigate accuracy of calculated displacement The movement of the shaking table is measured by laser displacement meter, and two acceleration meters are installed on the table. Though data from laser meter include long period noise, calculated displacement is rather consistent with laser meter, after filtering noise. Proposed digital filter is useful for on-site health monitoring measurement.
