Abstract
Documented observation of destruction distribution after seismic events suggest to topography effects on earthquake intensity. But there exist very few –if any- well documented case studies where topography effects are illustrated for strong ground motion. This is due to complex nature of seismic scattered wave by topographical structures to medium. Although some empirical correlations, obtained from statistical analyses, were proposed in different studies to consider this issue, but these correlations also may not be applicable in general or may be overestimation of what happen in reality. These difficulties and disadvantages can only be solved accurately, economically and under realistic conditions by advanced numerical methods. In this paper a powerful FE program (PLAXIS v.8.2) applied to carry out site response analysis of two dimensional topographic structures (trapezoidal non-alluvium valley) subjected to an earthquake (Manjil earthquake, IRAN, 1990). The applicability and efficiency of the program have been verified through some examples of site response analysis that their solutions are available in literature. At last, the results have been diagramed.

Documented observation of destruction distribution after seismic events suggest to topography effects on earthquake intensity. But there exist very few –if any- well documented case studies where topography effects are illustrated for strong ground motion. This is due to complex nature of seismic scattered wave by topographical structures to medium. Although some empirical correlations, obtained from statistical analyses, were proposed in different studies to consider this issue, but these correlations also may not be applicable in general or may be overestimation of what happen in reality. These difficulties and disadvantages can only be solved accurately, economically and under realistic conditions by advanced numerical methods. In this paper a powerful FE program (PLAXIS v.8.2) applied to carry out site response analysis of two dimensional topographic structures (trapezoidal non-alluvium valley) subjected to an earthquake (Manjil earthquake, IRAN, 1990). The applicability and efficiency of the program have been verified through some examples of site response analysis that their solutions are available in literature.
