Abstract
This thesis studies the effect of soil (site conditions) on the dynamic
behavior of structures. Full interaction between bedrock motion, subsurface
soil, substructure and superstructure are represented as a dynamic soilstructure
interaction problem using the fmite element method. Nonlinear
behavior of soil stiffness and damping ratios as a function of shear strain
amplitude, confining pressure and plasticity index are taken into account.
An advanced technique for earthquake simulation analysis is presented.
Improvements have been made to raise its accuracy. Different simulated
earthquakes for bedrock motion have been used to predict the effects of
various site conditions on the dynamic characteristics of surface ground
motion. Extensive studies have been carried out, including wide range of
soil and site condition, to develop enhanced design response spectra curves.
These enhanced design curves have been normalized to be used for
structural design purposes. Comparison between these enhanced curves and
recent international building codes is illustrated. Moreover, the effects of
site conditions, foundation types, location of tie beams and their inertias on
the dynamic response of an example framed structure have been examined.
