SEISMIC PERFORMANCE OF PRESTRESSED CONCRETE PILES AND PILE- PILE CAP CONNECTIONS. RESEARCH REPORT

The performance, strength and ductibility of prestressed concrete piles, and their connection to pile caps, subjected to severe seismic loading are investigated in this thesis. Knowledge of the strength and ductibility of the pile within its embedded length in the foundation material is of importance due to the large deformations which can occur during an earthquake, particularly at the interface of hard and soft layers of foundation material. Connection details are of interest since high moments, shear and axial forces need to be transferred to pile caps during earthquake loading. Two series of tests were conducted from which design tables and charts are obtained for the pile properties. The design tables are used to assess the enhancement factors of pile cross sections within the length or at the interface of the connection of the pile cap. The design charts are utilized to calculate the yield curvatures as well as the available curvatures and available curvature ductibility factors. Recommendations for future research are proposed.
