<P>PROBLEM TO BE SOLVED: To provide a vibration analyzer capable of easily and intuitively generating an optional acceleration (waveform) for being used for a time history response analysis and analyzing in real time vibration properties of the building due to earthquake vibration momentarily changing. <P>SOLUTION: Based on change of acceleration with time, acceleration waveform is generated by acceleration generating means 2 equipped with an acceleration sensor and transmitted to an information processing device 3. In the information processing device 3, the acceleration waveform is treated as a waveform of ground surface acceleration applied to the ground surface to support the building to be analyzed, and based on a parameter including mass and spring rigidity set on the basis of this acceleration waveform and the building, the amount of response displacement of the building to the ground surface acceleration is made to be continuously calculated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
