Based on the stress output from
the regular finite element analysis, a new weighted method (WFEM) was
developed to perform the global failure analysis and design for two
dimension geotechnical problems.
First, the local safety factor of
each element is calculated from the Mohr shear failure assumption.
Then the possible failure surface is searched throughout the defined
searching zone, like those slope stability softwares. The global safety
factor is defined as the weighted sum of local element safety factors,
only those elements on the final failure surface.
The advantages of this new method:
The new Hyperbolic-Theta Model
and 2D quadrate element are adopted to simulate soil. The linear
elastic materal model, beam element, and 2D quadrate element are used
for the nonsoil structure part. The input data file is similar to
those for regular FEM software, except it needs eight more points to
define a searching zone.
Software, manual, five examples,
and a reference paper were ALL zipped into the following "wfem15.zip",
for your downloading, FREE.
"HP DeskJet 600" was selected as the default printer
for the ".doc" WordPerfect 6.0 files, so, they might need some edit work to fit
different printer and wordprocessor. Because of the limited homepage space, I can not change
the files into other format. Sorry!
