WebJun 13, 2024 · In this current study, dynamic field tests have been conducted on a single pile to measure the frequency-amplitude responses. The effective mass with stiffness and damping are evaluated using the theoretical approach proposed by Novak ( 1971) from the measured dynamic response curves. WebNov 1, 2024 · The available solutions for piles subjected to lateral dynamic loads provide stiffness and damping that are frequency dependent. This means that at each frequency of a dynamic load, a unique value of the stiffness and damping exists.
