To ensure the safety of reinforced concrete structures against earthquakes, it is necessary to evaluate the safety of each member against the plastic rotation demand. In this study, a simplified method was developed to estimate the plastic rotation demand of the members on the basis of the results of elastic analysis/design. By using a story subframe model in regular multi-story moment frames, the relationship between the story-drift demand and the member plastic rotation demands was derived. In the proposed method, the effects of various design parameters, including the building configuration, member stiffness, redistributed moment, and story-drift ratio, were considered. The proposed method was applied to the seismic design of a moment frame and a dual system, and the prediction results were compared to the results of nonlinear analysis. In addition, the experimental verification to a small-scale multi-story moment frame was also made. Code: *************************************** |
