摘要: Abstract A hybrid method for the calculation of realistic synthetic seismograms in laterally heterogeneous, anelastic media has been used to model ground motion Tehran city. The records compare reasonably well with observed due 2004 Firozabad Kojor earthquake located 60 km north Tehran. ratio between response spectrum signals calculated along a varying structure, Sa(2D), and that at bedrock regional reference Sa(1D), shows high amplification seismic waves procedure can be readily implemented entire city, which experienced large historical earthquakes past, simply by extending analysis, made so far, space different scenario earthquakes, consistent local tectonics.
