Abstract
In this study, a comprehensive parametric analysis was performed on non-uniform excitation of V-shaped topography using the boundary element method in time domain. For this purpose, wave scattering analysis was carried out on a topography subjected to the SV-wave for different predominant frequencies and shape ratios. Based on the numerical results, new coherence and time delay functions are proposed to generate non-uniform ground motion for topographic irregularities. The efficiency and accuracy of the proposed functions for real engineering problems are indicated by comparison with observations reported in previous literature.
