Application of Boundary Element Method to Study the Seismic Response of Triangular Hills

Abstract eng:
For gaining insight into seismic response of 2D triangular hills and concluding their 2D amplification pattern in microzonation studies the results of parametric numerical analyses have been processed in both time and frequency domains. To achieve this goal the Direct Boundary Element Method (DBEM) is applied for calculating elastic wave propagation in two-dimensional triangular hills and clear perspectives of the amplification patterns of the hills are presented by considering the frequency-domain responses. It is shown that wavelength and site geometry are the independent key parameters governing the hill's amplification pattern. The effects of two aforementioned parameters are concerned in terms of periodic subintervals and shape ratios.
