|Title:||Cumulative Seismic Damage of Reinforced Concrete Bridge Piers|
|Published:||October 01, 1997|
|Abstract:||A comprehensive experimental study was undertaken in this research effort to investigate cumulative damage in reinforced concrete circular bridge piers. Twelve identical quarter-scale bridge columns, designed and fabricated in accordance with current AASHTO specifications, were tested in two phases. Phase 1 testing consisted of benchmark tests to establish the monotonic force-deformation envelope, the energy capacity under standard cyclic loads, and constant amplitude tests to determine the low-cycle fatigue characteristics of the bridge column. Phase 2 testing was composed of a series of analytically predicted displacement amplitudes representing the bridge response to earthquakes. The results of Phase 1 testing provided information on the fatigue behavior of reinforced concrete and Phase 2 provided data on the effects of load path on cumulative damage.|
