Abstract:

As a result of abutment spalling on the integral abutment bridge over 400 South Street in Salt Lake City, Utah, the Utah Department of Transportation (UDOT) instigated research measures to better understand the behavior of integral abutment bridges. The bridge was instrumented with survey targets and monitored each month for one year. The monthly surveys were also supplemented by a day-long survey. Measurements of temperature change and span length were obtained and used to show general trends in the movement of the 400 South Street Bridge. A detailed finite-element model was created and results from the model confirmed locations of stress concentrations at the bottom of the bridge girders. A simplified model was then created and used to show the same trends as observed in the survey data. The simplified model was then modified to conduct a parametric study on the effects of skew, span length, and temperature gradient. The results from this research were used to make conclusions and recommendations regarding the implementation of integral abutment bridges in the state of Utah.
