摘要：
Two recent studies on the shake table response of large-scale bridge columns are summarized. The first was undertaken to evaluate the adequacy of a new performance-based design (PBD) method for confinement steel in circular columns and the other study was focused on retrofit of substandard octagonal bridge columns supported on pedestals. The test results demonstrated the effectiveness of the proposed PBD for a predetermined curvature ductility. The retrofit studies showed the effectiveness of fiber-reinforced plastic fabrics in eliminating pedestal damage and the improvements in response when the column shear demand was controlled.
