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: This paper discusses the development of earthquake design criteria for the Southern Bering Sea—Aleutian Shelf region. The study reported herein was primarily motivated by a high level of seismic ...

Abstract: Complex foundation impedance functions were determined experimentally from the results of forced vibration tests conducted at an accelerograph station. Two independent vibration experiments were performed to obtain estimates ...

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‐) ...
