Title:
STUD-TYPE STEEL DAMPER
Document Type and Number:
Japanese Patent JP2023098991
Kind Code:
A
Abstract:
To provide a stud-type steel damper constituted by fixing a plurality of steel members having an H-shaped cross-section to each other in a state of being arranged in parallel, capable of efficiently drawing out the energy absorbing capacity of a region having small yield strength provided in a web of a central part of each steel member.SOLUTION: A stud-type steel damper, which is mounted between the upper and lower beams of a frame consisting of columns and beams, is constructed by joining flanges with multiple steel members having H-shaped sections in parallel. An opening is provided in the web at the center in the longitudinal direction of each steel member, and a shear panel made of a low yield point steel with low yield strength is arranged to close the opening and is joined to the web and the flange member. The thickness of the flange of the steel members is at least 22 mm. The joint between the flanges of each steel member is made in the area where no shear panel is provided in the longitudinal direction of the steel member.SELECTED DRAWING: Figure 1
