Response Spectrum Method for Kinematic Soil-Pile Interaction Analysis
The detailed seismic responses of pile-soil systems are usually evaluated by a three-dimensional finite-element model which requires a lot of computational resources. In the actual structural design for these models, a computationally efficient method with a reasonable accuracy is preferred from the viewpoint of cost and time. As for the seismic response of a pile-soil system, a kinematic effect due to the forced displacement of the surface ground is considered to be important, especially in soft ground, together with the inertial effect due to the inertial forces from superstructures. In this paper, a new response spectrum method in terms of complex modal quantities is developed for the evaluation of the maximum kinematic seismic response of the pile-soil model to the ground motion defined at the engineering bedrock surface as an acceleration response spectrum. The ratio of the pile-head moment due to the kinematic effect to that due to the inertial effect will be discussed in detail.
