Behavior of Pile to Bent Cap Connections Subjected to Seismic Forces
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.
