PRACTICAL METHOD FOR EVALUATING KINEMATIC STRESSES IN PILES
|

| 抄録（英）： |
Dynamic stresses in a pile comprise inertial σ■ and kinematic σ■ stresses. This paper describes a practical method for evaluating the latter stresses σ■ when the maximum acceleration of a design earthquake is given at the ground surface. The subsoil response, which is required to evaluate σ■, is determined from the first natural period and the modal-damping factor of the subsoil, incorporating nonlinear characteristics. The applicability of the proposed method is examined in comparison with a more rigorous method. The comparative studies show that σ■ and the non-linear behaviors obtained by the proposed method agree well with the rigorous analysis results. The applicability of the proposed method is confirmed from the viewpoint of practical seismic design of a pile.
