Beginning with the PREcast Seismic Structural Systems (PRESSS) program (1, 2), one of the concepts that have been studied by several researchers is the use of rocking systems to resist earthquake induced forces (e..g., 3, 4). These systems are often designed with prestressed post-tensioning tendons, which help these systems to self-center while minimizing structural damage during major seismic events. Understanding the contributions of different damping components during the response of these systems and interaction between them is an important phenomenon that has not received sufficient attention. To improve understanding of the energy dissipation mechanisms of rocking systems, two sets of tests have been performed. First a series of free vibration tests were conducted on a rocking column. The variables used in this test included the locations of the mass, lateral drift, initial prestressing and hysteretic energy dissipation. Next, a series of rocking wall systems have been completed. These tests were performed using a shake table for input motions with varying intensities. The variables used in the second set of tests included influence of cover concrete and initial prestressing. In addition to presenting both sets of experimental results from global and local perspectives, an assessment of different damping components during rocking response of the two systems will be presented.
