| 摘要： | This study focuses on critically evaluating confinement requirements suggested for plastic hinge regions of bridge columns suggested by California Department of Transportation (Caltrans). In addition to section analyses, a series of pushover and earthquake dynamic analyses were conducted on several bridge columns to formulate appropriate recommendations to improve the confinement requirements. It is shown that the plastic hinge length, ultimate compression strain and ductility demand should be revised to improve the seismic performance of bridge columns. In addition, the impact of unexpectedly high inelastic demands that some earthquake can impose on bridge columns should be adequately addressed. 16. |
