Abstract:

This report describes an investigation to quantify the behavior of precast, prestressed concrete double-tee bridge ; girders made with lightweight concrete. As part of the investigation, three bridge girders were salvaged from a ; decommissioned bridge in Coalville, Utah. Each girder was subjected to a cracking test to determine the residual ; prestress force after approximately forty-eight years of service life. Once the prestress losses were quantiﬁed, a ; ﬂexural capacity test was performed on each girder, as well as shear capacity tests performed at various distances ; from the support. The measured losses and capacities were compared to estimated values calculated according ; to procedures in the AASHTO LRFD Speciﬁcations. It was concluded that the AASHTO LRFD procedures for ; calculating prestress losses were accurate and the calculated shear capacities were conservative. However, the ; calculated ﬂexural capacities were not conservative, which is believed to be a result of deck deterioration. In ; addition to the physical tests, a nonlinear ﬁnite-element analysis (FEA) was conducted using ANSYS that was ; found to replicate the experimental behavior, failure mechanism, and magnitude.
