Accelerated Bridge Construction (ABC) Methods for Pile-Footing-Column Systems
Building on a previous project, the proposed research will advance the accelerated bridge construction method for bridge substructures using steel piles and precast pile caps and columns. The weight of the precast members will be reduced using hollow sections, which in turn will improve both construction tolerances and constructability. The hollow sections will be filled with in-situ concrete. The piles will be designed with temporary collars, which will eliminate the need to wait for the concrete to cure before continuing with the superstructure construction. The proposed research, funded jointly by the California Department of Transportation, will include a large-scale test unit which will incorporate both vertical and battered steel piles. The testing of the system will incorporate service level and extreme loads and ensure dependable performance of the new system and its components. As part of the testing program, the performance of the column and pile foundations will be examined systematically. Analytical models will be developed to realize the observed performance of the test unit and the components. Using the combination of analytical and experimental observations and findings from the previous phase of the project, appropriate design recommendations will be developed for improving bridge construction.
