Abstract

The partial collapse of Illinois Department of Transportation structure 020-3087 on October 1, 2019, provided IDOT with the opportunity to evaluate the in situ strength of a precast, prestressed concrete deck beam bridge after 50 years in service. An undamaged beam was transported to the Newmark Structural Engineering Laboratory and tested in three-point bending to failure on February 25, 2020. The beam supported a peak load of 33.14 kips before failure, an ultimate moment of 227.5 kip-ft. Upon failure, the concrete around the prestressing strands was removed to expose the strands. All strands were present; however, the strands were in a different configuration than shown on design drawings. None of the strands showed visible corrosion.
