235 5.1 Introduction The main objective of NCHRP Project 12-105 was to develop proposed AASHTO displacement-based design and construction specifications for the implementation of ABC column connections in moderate- and high-seismic regions. The project was focused on three types of precast column connection: (1)

236 Proposed AASHTO Seismic Specifications for ABC Column Connections Overall, the proposed acceptance criteria, the adopted coupler model, and the proposed testing methods were found viable for identifying existing or emerging couplers that could be used in the plastic hinge region of bridge columns. Appendix B of this report presents these in the AASHTO/ASTM format and language.

Proposed Specifications and Examples 237 The proposed equation was compared with those from other studies and design codes, and its advantages were discussed. After the embedment length was established, a detailed finite element analysis was performed to investigate the minimum size of column adjoining members when grouted ducts are used at the column ends.
