摘要

More reasonable seismic design can be achieved by considering the input loss effect of the soil-foundation interaction. However, there is no practical evaluation method of the input loss in the seismic design by means of the static analysis method for the foundation widely used in the railway field. A practical method for evaluating input loss using the static analysis method was therefore examined. First, a sensitivity analysis was conducted by varying both ground and pile conditions, and the input loss effect due to the pile foundations was investigated. Practical methods were then proposed for calculating the effective input coefficient by means of a seismic deformation method and for calculating response spectra based on the random vibration theory. Furthermore, the applicability of these methods was verified through comparison between the dynamic analysis results and the evaluated results.
