NEFCAD is a non-linear elasto-plastic analysis computer program
for frame structures and consists of a control program that manages the
database, an analysis and design engine and a graphical user interface
(GUI) for user data input.

ASEP is a computer program for inelastic analysis of arbitrary
reinforced and composite concrete sections. It can be applied for rapid
design, moment-curvature analysis and ultimate strength capacity
evaluation of arbitrary-shaped composite steel-concrete cross-sections
that are subjected to biaxial bending and axial force. The numerical
procedure implemented is very stable even when the section is close to
the state of pure compression or tension or when there are multiple
solutions, and it is not sensitive to the initial or starting values,
to how the origin of the reference loading axes is chosen and to the
strain softening exhibited by concrete in compression. Furthermore, the
proposed method can be applied to provide directly the ultimate
resistances of the cross-section, in the hypothesis that one or two
components of the section forces are known, without the need of knowing
in advance the whole interaction diagram or moment capacity contour.
ASEP capabilities include:
Interaction diagrams N-Mx-My
Moment capacity contours Mx-My for constant axial force
Moment-curvature analysis
Composite steel-concrete cross sections of arbitrary shape
Compute the required reinforcement area supposing that all
structural parameters are specified and, under given external loads,
the cross section reaches its failure either in tension or compression

GFAS (A Finite Element System for Geotechnical Applications) a product of Geostru Corporation
is a finite element package that has been developed specifically for
the analysis of deformation and stability analysis in geotechnical
engineering problems. GFAS is an easy-to-use yet powerful
geotechnical-engineering tool for the linear and nonlinear analysis of
homogenous or nonhomogenous structures in which soil models are used to
simulate the soil behavior. It features a full graphical interface for
pre-processing or post-processing and uses the Finite Element Method
(FEM) for 2D solids for its analysis purposes. The graphical interface
enable a quick generation of complex finite element models, and the
enhanced output facilities provide a detailed presentation of
computational results. The analysis procedures are fully automated and
based on robust numerical procedures.
