Abstract

The past numerical studies on SEISMIC BEHAVIOR of TOPOGRAPHIC FEATURES have been actually limited to individual single shapes. However, realistic observations in nature show that ground surface variation and its complexity is much greater and TOPOGRAPHIC FEATURES appear almost in complex forms. The main objective of this paper is presenting the results of a numerical study on SEISMIC BEHAVIOR of two adjacent 2D homogenous semi-sine shaped hills subjected to vertically propagating incident SV waves. It is shown that the combination of two ADJACENT HILLS generates an amplification pattern qualitatively similar to that of a single hill. The adjacency of the hills increases the AMPLIFICATION POTENTIAL at both crests, especially on that hill which possesses a smaller shape ratio. Although the area created amid the two ADJACENT HILLS shows a SEISMIC BEHAVIOR similar to the valley qualitatively, it is not equivalent quantitatively to the valley of the same shape ratio. The inside base of ADJACENT HILLS demonstrates a greater AMPLIFICATION POTENTIAL compared to the edges of the single valley with the same shape ratio, particularly against short and medium incident waves. It is also shown that adjacency effect could be considered as an effective factor in justifying some large AMPLIFICATION POTENTIALs reported in experimental observations.
