This paper presents results of inelastic pushover analyses of eight and twelve-story R/C buildings designed and detailed according to current seismic codes for the construction in medium seismicity areas. Two inelastic finite element packages were used in the analyses, namely Zeus-NL and DRAIN-2D. The former employs a detailed fiber modeling, while DRAIN-2D adopts the lumped plasticity modeling approach with member hysteretic rules simulating numerous experimental results of various structural members. The objective is to evaluate the redundancy and reliability of typical R/C buildings complying with current seismic provisions. The investigation employs different reliability factors and redundancy indices from the IBC-2003 code and from prior investigations. Differences between the seismic response from the two modeling approaches adopted in this study are highlighted. DRAIN-2D predictions of the ultimate strength of the eight-story building was found to be 10% lower than that of ZEUS-NL. DRAIN-2D results also indicated a three-story sway mechanism that was not detected by the refined fiber modeling of the eight-story building. Finally, a rational reformulation of reliability/redundancy factor is suggested. The study concluded that buildings adequately design and detailed to current seismic codes for medium seismicity regions have acceptable levels of reliability and redundancy.
