A Superposition Based Diffraction Technique to Study Site Effects in Earthquake Engineering

Figure 8

Spatial distribution of the amplitude response function over the free surface of a symmetrical V-shaped canyon with depth-to-width aspect ratio and dimensionless frequency . The first row compares the solution for each aspect ratio obtained by the region matching technique reported in Tsaur and Chang [5] (T&C) and the SBD approach (this work) with 1, 2, and 3 orders of diffraction.
