2 Presentation Outline Current Seismic Bridge Design Philosophy Improving Seismic Bridge Design with Innovative Materials Examples of Research Results Implementation into SR 99 Bridge

3 Current Seismic Design Philosophy Primary Seismic Performance Objective: Collapse Prevention Failure

4 Current Seismic Design Philosophy Failure Photo: H.G. Wilshire, U.S.G.S.

5 Current Seismic Design Philosophy Failure Photo: Caltrans

6 Current Seismic Design Philosophy Success

7 Current Seismic Design Philosophy May result in bridge closures Excessive column damage Excessive lateral deflection Limited access; may or may not allow even emergency response vehicles Extensive Repairs Patching of spalled concrete Shoring of spans Replacement Disrupts public transportation Major economic impact

8 Improve Seismic Design Performance Based Design Keep bridges operational Minimize repair need Minimize residual drift Reduce damage to plastic hinges Keep an energy dissipating system
