Title:
METHOD AND DEVICE FOR ANALYZING FLOOR VIBRATION
Document Type and Number:
Japanese Patent JP3852872
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently take countermeasures against vibration trouble of a floor.
SOLUTION: First to third data input means 20, 22 and 24 input physical data regarding the floor, beams supporting the floor, and columns supporting the beams respectively and a data writing means stores the inputted physical data in a storage device 19. Then a natural value analyzing means 32 analyzes natural values of the floor vibration by a Layleigh-Ritz method as a simple analyzing method according to the physical data stored in the storage device 19 and obtains the primary natural vibration frequency of the floor as a function of the thickness of the floor and the sectional size of the beams. Then a sensitivity analyzing means 33 calculates a differential coefficient regarding the thickness of the floor and the sectional size of the beams. Then an output means 34 displays the differential coefficient calculated by the sensitivity analyzing means 33 on a display device.
