Evaluation of Seismic Performance of Bridge Columns with Couplers and Development of Design Guideline
Accelerated bridge construction (ABC) relies heavily on prefabricated reinforced concrete members. One method to connect prefabricated columns to footings or cap beams is through the use of mechanical couplers. It is convenient to locate these couplers in the plastic hinge zone of the columns, even though current seismic codes do not allow couplers in plastic hinge zones in moderate and high seismic areas. Recent research has revealed the feasibility and sufficient seismic performance of columns utilizing couplers in the plastic hinge.
