Bridge Seismic Retrofit Feasibility Case Study Utilizing Ductile Fuses
Peter Dusicka
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 deve...
