Seismic Behavior and Retrofit of Bridge Knee Joints

The overall goals of this research are to obtain a better understanding of the seismic behavior of existing knee joints and to develop and evaluate the effectiveness of the retrofit measures for improving their performance in outrigger bents. The four objectives proposed in this project are to: (1) evaluate and define the vulnerabilities of outrigger bents under seismic and gravity loadings; (2) develop appropriate retrofit measures for outrigger knee joints that address the identified vulnerabilities; (3) evaluate through experimental testing the feasibility and benefits resulting from retrofit measures applied to outrigger bents; and (4) draw conclusions and make recommendations for practical retrofit methods for improving the performance and safety of outrigger bents in bridges.
