000009499 520__ $$2eng$$aPerformance-Based Plastic Design (PBPD) method has been recently developed to achieve enhanced performance of earthquake resistant structures. The design concept uses pre-selected target drift and yield mechanism as performance limit states. The design lateral forces are derived by using an energy balance equation where the energy needed to push the structure up to the target drift is calculated as a fraction of elastic input energy which is obtained from the selected elastic design spectra. Plastic design is then performed to detail the frame members and connections in order to achieve the intended yield mechanism and behavior. The method has been successfully applied to a variety of steel framing systems and validated through extensive inelastic static and dynamic analyses. This paper presents some modifications and refinements that have been developed for implementation in the PBPD method, especially for mid to high-rise Moment Frame (MF) structures. The refinements are focused on the design of frame members that are intended to remain elastic as part of the design yield mechanism so that the structure can better achieve the desired performance. The refined procedure is applied to a 20-story steel moment frame and validated by inelastic static and dynamic analyses. The results showed that performance of the PBPD structure is much improved over that of the baseline SAC frame, which was designed by the then current code practice.
