COLUMN-BEAM JOINING PART HAVING ENERGY ABSORBING MECHANISM

Japanese Patent JP3493495

B2

PURPOSE: To absorb vibration energy so as to restrain vibration of a building by installing fitting plates in the direction of the axis of a member of a flange intersecting part of a column and a beam of a column-beam joining part in such a manner as to be parallel to the web of the column or the beam in the form of a haunch to the relatively displaced, and making a visco-elastic body sheet adhere to the fitting plates.
CONSTITUTION: A fitting plate 3 is disposed in the direction of the axis of a member of the intersecting part of flanges 2a, 1a of a column 1 and a beam in such a manner as to be parallel to the web of the beam 2, and installed in the form of a haunch to be relatively displaced. At that time, there is provided a gap P for permitting displacement. Also on the lower side of the beam 2 of the inside flange 1a of the column 1, a fitting plate 4 is disposed in parallel to the direction of the axis of the member in the middle position between the fitting plate 3 and integrally installed. Thus, when vibration energy like an earthquake is applied to the joining part of the column beam, the fitting plates 3, 4 are relatively displaced in parallel. A visco- elastic body sheet 5 is interposed between the fitting plates 3, 4. By this arrangement, vibration energy is absorbed as shearing energy. Thus, vibration damping design taking energy absorption into consideration can be achieved.
