Slab Behavior of a Prestressed Concrete I-Beam Bridge Lehighton Bridge
The report presents the experimental results from the field test of the deck slab of a prestressed concrete I-beam slab superstructure. In the test program, SR-4 strain gages were attached to the top and bottom surfaces of the deck slab, along a superstructure cross-section near midspan. Measurements were made of the strains produced by the passage of an HS 20-44 load vehicle passing across the structure in each of nine load test lanes. Experimental values of stresses were compared with the corresponding typical allowable stresses, and experimentally determined bending moments were compared with values used in the design of the slab. The effects of the midspan diaphragm, the corrugated steel stay-in-place forms, and the local stresses produced by the wheel loads are discussed. (Author Modified Abstract)
