Abstract: Dynamic quick‐release and forced‐harmonic vibration tests were performed on a steel pipe pile embedded in soft saturated peat. The translational and rotational pile‐head impedances (stiffness and damping values) estimated ...

Abstract: Forced‐haimonic‐vibration tests, using an eccentric‐mass shaker, were conducted on two small but different concrete foundations. One foundation (Cholame 1E), located in central California, consisted of a 4‐in.–(10‐cm‐) ...
