A DIRECT BOUNDARY ELEMENT METHOD APPLIED TO STUDY THE SEISMIC RESPONSE OF TRIANGULAR VALLEYS:

摘要：

The direct boundary element method is well studied for the analysis of the seismic response of triangular valleys. The main purpose of this article is conducting the numerical parametric analyses in the time domain to gaining insight into amplification pattern of 2D triangular valleys. Clear perspectives of the amplification patterns of the valley are presented by investigation of the frequency-domain responses. It is shown that wavelength and site geometry are the independent key parameters governing the valleys amplification pattern.Some simple relationships are obtained based on study results which could be used in seismic microzonation and seismic design of structures founded inside the valley.
