PROBLEM TO BE SOLVED: To provide a vibration measurement method of a structure capable of measuring torsional vibration of the structure generated by an earthquake or the like.SOLUTION: A plurality of displacement gauges 1A, 1B for measuring respectively a displacement magnitude in the horizontal direction of a structure 11 are installed at an interval on a floor surface (horizontal installation surface) 12 of the structure 11, and torsional vibration of the structure 11 is calculated from each displacement magnitude in the horizontal direction of the structure 11 measured on each spot where the plurality of displacement gauges 1A, 1B are installed, and from the interval (installation interval L) at which the plurality of displacement gauges 1A, 1B are installed.SELECTED DRAWING: Figure 1 |
