Title:
COMPLEX ELASTOPLASTIC DAMPER
Document Type and Number:
Japanese Patent JPH07279477
Kind Code:
A
Abstract:
PURPOSE: To reduce responses against external forces from a low level to a high level, by an elastoplastic damper by use of a steel member.
CONSTITUTION: This damper is composed of a lead damper 2 yielding at a low stress and a steel plate damper yielding at a higher stress than the yielding stress of the lead damper. A lead damper 2 yields with the elastic deformation in a steel damper 3 at the actuation of the shearing force resulting from the relative deformation between mutually isolated structural members 4, 4 and the steel damper 3 yields at the actuation of the shearing force exceeding the yielding stress of the lead damper 2 and thereafter, the steel damper is deformed plastically together with the lead damper 2.
