Re-Classifying Bridges with Unknown Foundations

A practical, cost-effective and rational approach to re-classify bridges with unknown foundations is presented in this paper. The method is based on satisfying static equilibrium under appropriate loads for the existing bridge pier/bent conditions using three-dimensional, non-linear finite element analysis. The method is applicable to partially and fully-embedded piled-foundation sub-structures where physical measurements of the super-structure and top of the foundation elements (layout, type, and size) can be made. The computed pile embedment using the proposed method is remarkably in close agreement with the actual embedment for bridges referenced in this paper. The approach presented in this practice-oriented paper can provide confidence in assessing the "unknown foundation" bridges and will expedite the screening of these bridges to protect the public. The methodology can also be used to validate embedment determinations done by Non-Destructive Testing (NDT) methods in previous or current projects and to guide any future NDT.
