Abstract
This thesis studies the different parameters that may affect the seismic
response of braced diaphragm walls’ (either strutted or anchored walls).
Full interaction between bedrock motion, subsoil and different structural
elements are represented as a dynamic soil-structure interaction problem
using the finite element method. Nonlinear behavior of soil is represented
using an equivalent linear model. The used input motion is based on
artificial earthquake time history. Extensive parametric studies have been
carried out to investigate the effect of site conditions, as well as, system
configuration on the overall behavior. The results showed that the
anchored wall system experiences considerably lower straining actions in
different structural elements, while the strutted wall system is better from
the site response point of view. Finally, recommendations are presented to
geotechnical engineers who may face the problem of supporting deep
excavation in active seismic areas.
