An experimental study of a passive energy dissipation tension-compression
yielding brace or buckling restrained brace has been
conducted. The Confined Yielding Damper (CYD) consists of a steel
yielding core confined within a tube filled with non-cohesive media. The
external tube and confined non-cohesive media provide lateral stability
to the core enabling the device to yield in compression as well as
tension. This device is similar to the Unbonded Brace developed by
Nippon Steel of Japan. Fourteen full-scale CYDs were tested to
determine the effect of varied confining media, perforation blocking
configuration, and a random displacement history. Based on the
Confined Yielding Dampers tested relatively stable and symmetric
hysteretic damping can be achieved with the CYD device. / Graduation date: 2003
