Electronic Theses and Dissertations

This thesis is the result of a study undertaken at the request of the South Dakota Department of Transportation (SDDOT) to determine the probable cause of a specific type of cracking that was observed in a series of reinforced concrete box girder bridges. The cracking consists of horizontal cracks through the end diaphragms of the girder and horizontal cracking over the interior bents. Typical crack patterns obtained from information supplied by the SDDOT are shown in Figure 1.
