Seismic Performance Design Criteria for Existing Bridge Bent Plastic Hinge Regions
| 项目名称： | Seismic Performance Design Criteria for Existing Bridge Bent Plastic Hinge Regions |
| 摘要： | The main objective of this research is to quantify the steel and concrete strain limits to be used for the seismic assessment of bridge bents considering the operational performance design criteria of existing reinforced concrete bridge bents. Multi-column bents are typical for bridges in Oregon and are therefore more representative of the need to gather performance related data. The proposed research is for experimentally evaluating large-scale reinforced concrete subassemblies representing critical parts of the bents. These primarily represent column-to-crossbeam and column-to-foundation aspects of the bent. Of key interest from the experiments are the monitoring of material strains and deformations as the bent reaches target performance levels. |
