SEISMIC: Bridge Design for Earthquake Fault Crossings: Synthesis of Design Issues and Strategies

This proposed research plan is aimed at translating previously completed research into products that can be easily implemented by bridge engineers. Specific products that will be developed during this project are: (a) Report on independent verification of the reliability of the three previously developed procedures; (b) Examples for the use of the three procedures for different types of bridges, different fault types, and different orientation between the bridge and fault; and (c) Procedures that are clear and can be put into Caltrans Memo to Designers and Seismic Design Criteria. The proposed research plan consists of seven tasks: (1) Identification of Bridge Examples; (2) Selection of Ground Motion Histories; (3) Development of Computer Models; (4) Evaluation of Previous Procedures; (5) Review of Analysis Approaches for Practical Use; (6) Development of Example Problems; and (7) Development of Recommendations for Bridges in Fault-Rupture Zones. This research will use realistic bridge models for independent evaluation of the three previously developed procedures, investigate impediments to their practical application and suggest possible solutions, develop simple to follow example problems for different scenarios, and provide recommendations to Caltrans that can be offered for adoption in the next Seismic Design Criteria and Memo to Designers.
