The design concept uses pre-selected target drift and yield mechanism as performance criteria. The design base shear for selected hazard level is determined by equating the work needed to push the structure monotonically up to the target drift to the corresponding energy demand of an equivalent SDOF oscillator. The design of frame members is then carried out by plastic method. This paper presents development of the PBPD approach as applied to reinforced concrete special moment frame (RC SMF) structures. RC structures present special challenge because of their complex and degrading ("pinched") hysteretic behavior. In order to account for the degrading hysteretic behavior the FEMA 440 C2 factor approach was used in the process of determining the design base shear. Four baseline RC SMF (4, 8, 12 and 20-story) as used in the ATC-63 Project and designed to comply with the requirements of ACI 318-05 and ASCE/SEI 7-05 were selected for this study. Those frames were then redesigned by the PBPD approach. For response evaluation purposes, the baseline code compliant frames and the PBPD frames were subjected to extensive inelastic pushover and time-history analyses. The results showed that the PBPD approach can be successfully applied to RC structures as well, and that the responses of the example moment frames were much improved over those of the corresponding baseline frames.High-rise structure | Performance-Based design | Plastic design | Special moment frameconference paper2-s2.0-85013908606https://api.elsevier.com/content/abstract/scopus_id/85013908606
