In such analysis, the bottom of the 1D soil column, at which the input motion is imposed, is assumed to be horizontal. In this study, a series of two-dimension ground response analyses are performed for hypothetical sites with different bedrock inclinations and sediment thickness. 1D analyses are also carried out for various locations of these sites. We then compare the surface response predicted from 1D and 2D analyses. We report how the bottom boundary type (rigid or compliant) affects the difference in the computed ground response. ? 11th National Conference on Earthquake Engineering 2018, NCEE 2018: Integrating Science, Engineering, and Policy.
