Chapter 5, Problem 5.10QPP

A timber pile 400 mm in diameter is subjected to the following axial compressive loads: $\text{dead}\text{=600}\text{kN,}\text{live=250}\text{kN,}\text{earthquake}\text{=}\text{200}\text{kN}\text{.}$ If the allowable compressive stress in the pile using ASD methods is 8.28 MPa, is this pile adequate?
