TRB's National Cooperative Highway Research Program (NCHRP) Research Report 864: Seismic Evaluation of Bridge Columns with Energy Dissipating Mechanisms, Volume 1: Research Overview and Volume 2: Guidelines describes the evaluation of new materials and techniques for design and construction of novel bridge columns meant to improve seismic performance. These techniques include shape memory alloy (SMA), engineered cementitious composite (ECC), fiber-reinforced polymer (FRP), and rocking mechanisms. The guidelines contained in Volume 2 explore a quantitative evaluation method to rate novel columns as well as design and construction methods for SMA-reinforced ECC columns, SMA-reinforced FRP-confined concrete/columns, and FRP-confined hybrid rocking columns. The project explores the behavior of the selected columns and develops proposed design guidelines according to the AASHTO LRFD Bridge Design Specifications and the AASHTO Guide Specifications for LRFD Seismic Bridge Design. Appendices A-I are available online.

This report describes a joint analytical and experimental research program which investigated the influence that flares have on the structural behavior of columns. The program also verified the potential seismic performance issues associated with flared columns. Ten model columns were constructed and tested in two phases, upside down, as simple cantilevers. The columns featured both large and heavily reinforced structural flares or small, light reinforced, non- structural flares. A prismatic reference column, as-built/as-designed column, and retrofit/improved flare designs were tested for both phases. Practical solutions for analyzing, design, and retrofitting flared columns are proposed, based on this research.
