Abstract:

In China, composite foundation has been widely used in civil engineering. What is the seismic response of this type of site? This is an important issue as to the input earthquake motion for structure design. By using the two-dimensional finite element program–FLUSH, the ground surface peak acceleration and acceleration response spectra of different replacement ratios under different ground motion inputs are calculated. The influences of replacement ratio on seismic response are studied; and some valuable results are obtained.

Key words: replacement ratio, input motion, seismic response, FLUSH
