Dynamic Evaluation and Design of Prefabricated Concrete Bridge Rails

The scope of work outlined below, builds upon the results of the Accelerated Bridge Construction-University Transportation Center (ABC-UTC) research project completed in Phase I. Tasks include: Task 1: Review of ABC-UTC Project (Phase I) and move forward with details for Two Precast Barrier Concepts for Dynamic Evaluation and Development of Design Methodology; Task 2: Conduct Numerical Modeling and LS-DYNA Simulation using Phase-I data; Task 3: Perform Impact Load Investigation on Two Prototype Designs; Task 4: Refine of Designs based on outcomes of from Task 3; Task 5: Perform Full-Scale Crash Tests on a Concrete Barrier-Deck Subassembly for Loads Corresponding to TL-4 and TL-5; Task 6: Calibrate Numerical Models; Task 7: Complete Parametric Study and Design Optimization; Task 8: Development Design, Construction and Implementation Guidelines; and Task 9: Conduct Life-Cycle Performance and Cost Analysis.
