Bridge Seismic Retrofit Feasibility Case Study Utilizing Ductile Fuses

Peter Dusicka, Portland State University

Summary:

In an effort to increase the seismic resiliency of our transportation network, a performance centric retrofit measure has been developed as part of State funded research and evaluated through to large scale laboratory setting. With an eye toward implementation, this technology transfer proposal aims to conduct a feasibility study on incorporating this retrofit measure with a recently developed ductile fuse technology and applying the retrofit to a real bridge case study. The intent is to develop sufficient information from the case study to be in a position to then move toward detail design and implementation phase. The outcomes of the project will have direct short term benefits for the State agency, but the lessons learned can inform and potentially enable the application of this retrofit nationwide.

Impacts:

Past research has developed the concept and conducted laboratory validations, but this project aids in transferring the developments to the field by applying the measure to an actual bridge site. If successful, this retrofit could be adopted more widely, thereby influencing the design practice.
