Abstract
A five-story one-third scale model structure of about 50 tons weight was tested on the shaking table at the Earthquake Engineering Research Center, U.C. Berkeley to study the earthquake resistant characteristics of an eccentrically X-braced structure. The eccentric bracing was created by a deliberate introduction of offsets into the brace-beam connections. The eccentric beams, designated shear links, yielded mainly in shear. Three sets of shear links, designed to be replaceable, were sequentially installed into the structure and tested to destruction.
