Static Design for Laterally Loaded Rigid Monopiles in Cohesive Soil

Rigid monopiles with small slenderness ratios (i.e., ratio of monopile embedded length to outer diameter) are widely used as foundations resist lateral load and moment transferred from superstructures, e.g., large diameter steel pipes by offshore wind turbines piers in electric utility industry or sound barriers. A design model for laterally loaded rigid cohesive soil is presented this paper. The proposed assumes a constant depth rotation point well trilinear distribution reaction along the monopile, introduces mobilization coefficient quantify magnitude mobilized under certain applied at head. relationship between head established back-analyzing test results measured series pile tests, then general procedure recommended. feasibility reliability validated against three cases numerical simulations on piles soils. It shows that study’s produces relatively satisfactory prediction nonlinear load-deformation response, can be sites undrained shear strength being uniform increasing linearly depth.
