Severe earthquakes continue to cause major catastrophes. Many devices in
active, hybrid, andsemi-active structural control systems which are used as controllable
force devices are costly to build andmaintain. The passive control reinforced concrete
frame (PCRCF) reinforced with high strength steel only inthe columns presented here
provides structural systems more resistance to lateral earthquake loadings
atcomparatively lower cost. The effectiveness is demonstrated by a nonlinear static
analysis using fiber modelfor a single story single bay frame. The study shows that the
use of high performance steel in columns pre-vents formation of plastic hinges at the
critical column base sections and failures are always initiated by re-inforcement yielding
at the beam ends. Furthermore, after experiencing severe lateral drift, the passive con-trol
design has small residual displacements compared to ordinary reinforced concrete
frames. PCRCF re-habilitation and strengthening can be achieved more easily as
compared with ordinary reinforced concreteframe.
