Seismic Evaluation and Retrofit of Bridge Substructures with Spread and Pile-Supported Foundations
This study investigated retrofitting measures for improving the seismic performance of the substructures of existing bridges. Retrofit measures fir both pile-supported and spread footings were investitgated. Experimental tests were conducted on 1/3-scale footing and column assemblages which incorporated details that were selected to represent deficiencies present in older bridges. Retrofit measures were applied to both the columns and footings. The specimens were subjected to increasing levels of cycled inelastic lateral displacements under constant axial load. Specimen performance was evaluated on the basis of load capacity, displacement ductility, strength degradation and hysteretic behavior.
