A wood pile driven into the earth supports a load P=400 KN entirely by friction along its sides (see figure). The friction force f per unit length of pile is assumed to be distributed over the surface of the pile. The pile has length L=2m, cross sectional area A=1500 square mm, and modulus of elasticity E=30000 MPa. Include free body diagrams to illustrate derivations. Determine the deformation of the pile

Load and resistance factor design

Load and resistance factors design (LRFD), also known as Limit state design (LSD), refers to the design method used in building engineering. A boundary condition is a condition of a structure where it can no longer meet the relevant design requirements. The condition may refer to the load level or other actions on the structure, while the terms refer to the integrity of the structure, suitability for use, durability, or other design requirements. A structure designed for LRFD is limited to keeping track of all possible actions during its design time and is always ready for use, with the appropriate level of reliability in each boundary condition. LRFD-based construction codes clearly define the appropriate levels of reliability in their instructions.
