Nonlinear response of single piles under lateral inertial and seismic loads

摘要: Abstract A macroscopic model that consists of distributed hysteretic springs and frequency dependent -pots is utilized to the lateral soil reaction a practical method based on one-dimensional finite element formulation developed compute nonlinear response single piles under dynamic loads. The physically motivated, adequate for cohesive cohesionless soils, involves standard geotechnical parameters. Only two parameters have be calibrated by fitting experimental data. Hysteretic radiation damping are modeled realistically within range amplitudes frequencies. validated against five well instrumented full-scale experiments typical values model-parameters provided. Subsequently, study seismic piles. Finally, used predict inertial one in foundation Ohba bridge near Tokyo, Japan.
