Structural Evaluation of LIC-310-0396 Box Beams with Advanced Strand Deterioration

STATEMENT OF NEED: A box beam structure recently collapsed in Pennsylvania. This structure type represents approximately 10% of the total square footage of the Department's bridge inventory. More information is needed to inspect, rate and manage the Department's inventory of precast box beam structures. OBJECTIVES: The objective of this study is to obtain field samples, perform material and strength testing as described below to create a proportional relationship between visual observations, inspection rating, and structural analysis modeling for load capacity. RESEARCH TASKS: 1) Document and measure visual observations. 2) Transport, test, and dispose of seven beams. 3) Perform full scale load testing to failure on four beams. 4) Test six more cross sectional beam sections from beams not load tested. 5) Collate deterioration data and full scale test information to develop a structural analysis model for load capacity. 6) Recommend changes to the Department's current inspection practices. DELIVERABLES: Recommendations of changes to inspection practices and reports as required.
