Design Procedures for Buildings Incorporating Hysteretic Damping Devices

摘要

This paper outlines design studies and large-scale tests of tension/compression yielding braces (also called "unbonded braces") in support of their first applications in the United States. The core steel in these braces provides stable energy dissipation by yielding under reversed axial loading, while the surrounding concrete-filled steel tube resists compression buckling. A slip surface or unbonding layer separates the steel core from the surrounding tube.
