Retrofit of Split Bridge Columns

D. I. McLean / M. H. El-Aaarag / P. D. Rogness

Many older bridges in Washington State contain split reinforcement columns as common members between adjacent bridge sections. The split detail was incorporated in columns to allow for movements in the bridge due to temperature and shrinkage effects. It is expected that these split columns will perform poorly in the event of a significant earthquake. This study investigated retrofitting measures for improving the seismic performance of existing split columns. Experimental tests were conducted on one-third scale split column specimens which were representative of the split columns present in the Spokane Street Overcrossing near Seattle. Various retrofit measures were evaluated. Specimen performance was evaluated on the basis of load capacity, displacement ductility, and hysteretic behavior.
