Explicit Frequency-Dependent Equations for Vertical Vibration of Piles
Publication: Practice Periodical on Structural Design and Construction
Volume 22, Issue 2
Abstract
Practicing engineers generally obtain stiffness and damping coefficients for dynamic design of pile foundations from design charts. The design charts require multiple interpolations and produce approximate frequency-independent coefficients. Explicit expressions consistent with the underlying theory for the vertical vibration of single piles are presented in this technical note. These expressions are easily implemented in a computer program, such as a spreadsheet, for design use. The proposed method preserves the frequency-dependent nature of the dynamic coefficients and enables one to account for the true condition of the pile tip. The effectiveness of the proposed method is illustrated with numerous examples.
