Extremely severe earthquakes, however, might cause large story displacement even for frames with the dampers. This paper presents a new bracing system for preventing large story displacement. The system uses wire ropes as brace members to eliminate brace-buckling entirely. The braced frames can increase the lateral strength without reducing energy dissipation characteristics of the moment frames by delaying the brace action. Comparison of the loading test results for the portal steel moment frames with and without wire-rope bracing members shows the fundamental characteristics of the bracing system. Numerical response analyses are performed for the three-story moment-resisting frames with and without the bracing and damping members. The characteristics and effectiveness of the bracing system are discussed in light of those test and analysis results.
