Book excerpt: As jointless bridges become more popular, there is a greater need to understand all aspects of their behavior. Significantly more research has been conducted on integral abutment bridges than there has been on semi-integral abutment bridges, therefore there is a need for more investigation into this type of bridge. Parametric studies on jointless bridges in the past often dealt with variations of the superstructure like altering the span length or skew. This research is an examination of a unique case for a jointless bridge that aims to provide a look into the behavior of the substructure. The subject for the research is a semi-integral abutment bridge with turned back wingwalls and drilled shafts. Semi-integral bridges are less common than integral bridges, and one with turned back wingwalls is constructed even less frequently. The turned back wingwall style of this bridge makes it a good subject for research because little is known about the effect of wingwall orientation on the stress patterns throughout semi-integral abutments. This research will provide a look into the behavior of a semi-integral abutment as the wingwall angle is changed from turned back to flared.
