|Title:||DYNAMIC ANALYSIS OF LATERALLY LOADED PILES USING SUBGRADE REACTION APPROACH|
|Authors:||Kumar, Vishnu S.|
LATERALLY LOADED PILES
|Abstract:||Lateral vibration of piles is an important consideration in the design of piled structures subject to dynamic excitations due to earthquake, wind, operation of machines and waves in offshore environments. In the past two decades, various models have been used to take the soil-pile interaction in the dynamic response analysis of pile foundations. Among those, Winkler models are the simplest and numerically most efficient ones. In the present study, a mathematical model was formulated to study the response of circular pile to laterally applied dynamic loading. The analysis was carried out considering fixed headed pile having floating tip at the base. The influence of soil type, pile length and pile diameter on the response of pile was studied and the results were presented. The modulus of subgrade reaction approach was used and numerical methods such as finite difference technique and Wilson's 0 method were employed. The formulation was programmed in MATLAB for analysis. Keywords: Lateral Vibration, Subgrade Reaction, Dynamic Loading|
