Seismic Performance of Circular Bridge Columns Designed in Accordance with AASHTO/CALTRANS Standards
Limitations of present procedures for the design of bridge columns to withstand seismic loads are discussed. Techniques for achieving the earthquake resistant capabilities are described and new design criteria, based on acceptable damage indices as functions of earthquake magnitude, distance, and structural importance, are proposed. Using the proposed procedure and criteria the performance of 72 representative bridge columns designed in accordance with 1992 CALTRANS specifications is analyzed. Analysis parameters included earthquake magnitude, distance from epicenter, subsurface soil characteristics, column aspect ratio, and normalized column axial load. Design charts, based on allowable damage index versus earthquake magnitude, are developed and retrofit strategies are discussed for those designs which do not meet the proposed design criteria.
