The Effects of Load History and Design Variables on Performance Limit States of Circular Bridge Columns – Volume 2: Experimental Observations

This report discusses a research program aimed at defining accurate limit state displacements which relate to specific levels of damage in reinforced concrete bridge columns subjected to seismic hazards. Bridge columns are designed as ductile elements which form plastic hinges to dissipate energy in a seismic event. To satisfy the aims of performance based design, levels of damage which interrupt the serviceability of the structure or require more invasive repair techniques must be related to engineering criteria. For reinforced concrete flexural members such as bridge columns, concrete compressive and steel tensile strain limits are very good indicators of damage. This report is the second of three volumes and presents detailed data and test summaries of the experimental portion of the work. In total 30 large scale reinforced concrete bridge columns are reported in this volume. Recommendations for design and analysis can be found in Volumes 1 and 3 of this report.
