Abstract:

The shear wave velocity of soils has important influences on response spectra. The 235 models of seismic site response, which belong to different site categories, are selected and constructed. And 12 pieces of varying amplitudes and frequency content acceleration time history are artificially made. The effects of the shear wave velocity of soil surface layer on design spectra platform are studied using one-dimensional equivalent linear wave propagation method of soil earthquake response, the functions between platform value of surface design response spectra and the variation rate of shear wave velocity are statistically provided. The results show that there is negative relationship between platform value of surface design response spectra and the variation rate of shear wave velocity and their mathematical model is a one-order exponential function.

Key words: site category, shear wave velocity, design spectra platform, acceleration time history, soils
