Abstract
This paper describes an analytical study with the purpose to gain some new understandings of the behavior of motion amplification in both horizontal and vertical components at liquefiable sites. By using a verified, effective-stress based nonlinear procedure, a series of numerical tests of a liquefiable sand deposit subjected to simultaneous action of horizontal and vertical shaking of various levels are carried out. To account for the characteristics of near-source motion, realistic array records of strong motion due to the Kobe earthquake of 1995 are employed to produce a variety of intensities of input motion in horizontal and vertical components. An extensive analysis of results for various loading cases is presented and, particularly, comparisons of the motion behavior and associated soil response between the case of horizontal input motion only and the cast of combination of horizontal and vertical input motion are made.
