• Abstract:
  Currently the South Carolina Department of Transportation employs a detail of a plain pile embedment for the ; connection between precast prestressed piles and cast-in-place bent caps. This connection has proved beneficial in terms ; of time and cost associated with construction, and has been previously investigated albeit in a limited capacity. As such ; an improved understanding of the behavior of the connection is warranted. The University of South Carolina has ; concluded a research program focusing on the behavior and design of this specific connection detail. ; South Carolina contains the highest level of seismicity along the east coast of the United States. The state relies heavily ; on the transportation infrastructure and a high level of confidence in bridge design practices is essential. This research ; began with a focus on the evaluation and understanding of the current detail employed in the connection between precast ; prestressed piles and cast-in-place bent caps. The work continues with the investigation of parameters that affect this ; connection detail and proceeds with potential improvements to the detail. The connections are evaluated in terms of ; moment capacity, ductility, and damage mechanisms. Findings indicate that when constructed with an appropriate ; embedment length the connection at interior portions of a bent cap is able to achieve desirable response. Connections at ; exterior portions of bent caps are also shown to respond desirably given sufficient pile embedment depth along with ; appropriate detailing of the bent cap.
