A new analytical solution for horizontal vibration of floating pile in saturated soil based on FSSP method
This paper presents a novel analytical model based on a fictitious saturated soil pile (FSSP) model, Biot's theory, and the Novak plane strain model for analyzing the horizontal vibration of a floating pile in saturated soil. First, the horizontal displacement of the saturated soil and horizontal resistance to the pile were determined using the separation variable method and potential functions. Next, the horizontal vibration response of the pile was obtained by deriving differential equations specific to the FSSP, considering its complete contact with the solid pile. The analytical model was then validated by reducing the proposed solution and comparing it with solutions presented in the literature. Finally, the effects of various soil parameters, such as the FSSP length, damping ratio, elastic modulus, and porosity, on the horizontal vibration response of the floating pile were analyzed.
期刊介绍:
The journal aims to encourage and enhance the role of mechanics and other disciplines as they relate to earthquake engineering by providing opportunities for the publication of the work of applied mathematicians, engineers and other applied scientists involved in solving problems closely related to the field of earthquake engineering and geotechnical earthquake engineering.
Emphasis is placed on new concepts and techniques, but case histories will also be published if they enhance the presentation and understanding of new technical concepts.
