Conventional steel moment-resisting frames (MRFs) are currently designed to form a global plastic mechanism under the design basis earthquake (DBE) by developing plastic hinges at the ends of the beams and the bases of the columns. This design methodology offers many advantages, including collapse prevention and initial economy; however, plastic hinges in structural members involve difficulty to inspect and repair damage and local buckling as well as residual drifts. The socioeconomic losses associated with damage and residual drifts are repair costs, increased downtime, and possibly demolition due to the complications associated with large residual drifts (McCormick et al. 2008).
A challenge of modern earthquake engineering is the development, standardization, and practical implementation of resilient minimal-damage structures with the inherent potential to...
