Abstract:
To study the impact of the new PBSD guidelines on a national level, 13 different cities were selected from across the United States. These cities are located both in high-seismic zones and lower zones. Both a 100-year and 975-year return period design were assessed for each location, and a range of column longitudinal steel content and aspect ratios were considered. Two different methodologies for estimating inelastic displacement from elastic response spectrum analyses were used. This presentation will present the results of this study and will bring to light an important finding relative to the way AASHTO currently estimates structure displacement using elastic analyses.
