| Research Abstract |
The displacement-restraint bracing system using round steel bars was investigated. The fundamental characteristics of that system were revealed through cyclic loading tests of portal frames. The seismic resistant properties of the frame with the proposed bracing systems were examined through seismic response analysis for low-rise steel frames. Furthermore, for the purpose of increasing energy dissipation capacity of moment frames, damping devices with dampers were developed.
