This study aims to calculate exact natural
frequencies of piles partially embedded in elastic soil by using transfer
matrix method (TMM). The elastic soil is considered as Winkler foundation model
using linear springs. The piles are modelled as Timoshenko beam-columns. The
transfer matrices of piles are constructed after obtaining end forces and end
displacements of piles using governing equation of motion of Timoshenko
beam-columns. Different soil conditions are used to show their effects on
natural frequencies of piles partially embedded in Winkler foundation.
Moreover, the results are tabulated comparatively with finite element solutions
that obtained from structural analysis software SAP2000.
