A series of hypothetical reinforced concrete frames is proportioned using a maximum allowable period criterion and evaluatec for expected maximum displacement response using a maximum allowable period criterion and evaluated for expected maximum displacement response using non-linear dynamic analyses and a suite of ground motions. Results indicate that for the reinforced concrete structural systems considered in the study, proportioning for gravity loads will provide sufficient stiffness in central and eastern U.S. Moderate seismicity.
