Multi-Hazard Bridge Design--Risk Evaluation and Risk Management through Load and Resistance Factor Design (LRFD) Calibration

Bridge reliability assessment and calibration of Load and Resistance Factor Design (LRFD) is the foundation of evaluating all risk related to the highway system and a critical step to optimal management strategy. Extreme events such as earthquakes (displacement-based), floods, and coastal storms/hurricanes are among the loads/conditions for which reliability of bridge performances are not clear. This task aims at evaluating the safety with proper probabilistic basis to enable improvement in design and optimization of investment.
