INTRODUCTION
VERSAT-2D is a software package consisting of three computer programs,
namely, VERSAT-2D Processor, VERSAT-S2D and VERSAT-D2D. These three components
of VERSAT-2D function independently. Interactions among them take place through
data files saved in a Windows Explorer file folder.
VERSAT-2D Processor is a Windows based graphic interface program. It
serves as a pre and post processor for VERSAT-S2D and VERSAT-D2D. The program is
used to generate a finite element mesh, define soil zones, assign material
properties, define boundary conditions, assign pressure loads, and generate
input data for VERSAT-S2D & VERSAT-D2D. The program can also display and plot
results from analyses such as stresses, displacements, accelerations, pore-water
pressures, and a deformed mesh.
VERSAT-S2D is a computer program for static 2D plane-strain finite
element analyses of stresses, deformations, and soil-structure interactions. The
static analyses can be conducted using stress-strain constitutive relationships
from linear elastic model to elasto-plastic models, i.e., Mohr-Coulomb model and
Von-Mises model. This program can also be used to compute or determine static
pre-existing stresses for use in a subsequent dynamic finite element analysis.
Main features of VERSAT-S2D are:
Linear elastic model; Von-Mises model;Mohr-Coulomb model; Stress level dependent
stiffness parameters; External load applications; Staged construction by adding
layers; Staged excavation by removing layers; Pore water pressure application;
Calculation of stresses and deformations caused by strain-softening of soils;
Simulation of sheet pile wall and anchors; Updated Lagrangian analysis; Factors
of safety calculation; Gravity on and off ; Calculation of pre-existing stresses
for use in a dynamic analysis using VERSAT-D2D; 4-node, 6-node and 8-node solid
elements to represent soils; 2-node line elements to represent sheet pile walls
(beam) or anchors (bar/truss); Use of any consistent units and sign conventions
VERSAT-D2D is a computer program for dynamic 2D plane-strain finite
element analyses of earth structures subjected to dynamic loads from
earthquakes, machine vibration, waves or ice actions. The dynamic analyses can
be conducted using linear, or nonlinear, or nonlinear effective stress method of
analysis. The program can be used to study soil liquefaction, earthquake induced
deformation and dynamic soil-structure interaction such as pile-supported
bridges. Main features of VERSAT-D2D are:
Application of horizontal, or
horizontal and vertical, ground motions at the base; Application of a
load-time-history at any nodal points; Global force equilibrium enforced at all
time; Linear elastic model; Non-linear hyperbolic stress-strain model for sand;
Non-linear hyperbolic stress-strain model for clay; Stress level dependent
stiffness parameters; Effective stress model including dynamic pore water
pressure; Three models for computing dynamic pore water pressure; Mohr-Coulomb
failure criterion; Modified stiffness parameters by dynamic pore water pressure;
Calculation of ground deformations caused by soil liquefaction; Calculation of
factor of safety against liquefaction; Simulation of sheet pile wall and
anchors; Updated Lagrangian analysis; Gravity on and off; Free-field stress
boundary; 4-node solid elements to represent soils; 2-node line elements to
represent sheet pile walls (beam) or anchors (bar/truss); Use of any consistent
units and sign conventions
