Seismic Retrofit Technical Presentation - SEI LA Chapter

The primary performance standard for retrofitting bridges in California is to prevent the structure from reaching the collapse limit state for the Design Earthquake. The collapse limit state is defined as the condition where any additional deformation will potentially render a bridge incapable of resisting the loads generated by its self-weight. The goal of this “No Collapse” performance standard is to protect human life. In this presentation, Mr. Joshi talks about the unique methodologies used for structural analyses and innovative techniques used for determining the seismic retrofit strategy of bridges in the Los Angeles Region.
