 Modeling Features
The SAFE slab is idealized as an assemblage of area, line and point objects.
Area objects are used to model slabs, openings, soil supports, and
surface loads. Line objects model beams and wall supports and loads.
Point objects are used for column supports and concentrated loads. With
relatively simple modeling techniques, very complex slab systems may
be considered.
The geometry of the slab can be unsymmetrical, and the thickness of the
slab may vary. Spacing of supports and loads may be completely arbitrary
and is not limited to the uniform spans typically associated with
equivalent frame techniques.
Construction or expansion joints may be modeled with or without shear
transfer by assigning bending and shear releases to the line object that
represents the joint.
Column and wall supports can provide both vertical stiffness and rotational
stiffness to give a more accurate representation of the distribution
of forces in the slab.
- Assign soil supports using subgrade modulus, SAFE automatically adjusts
nodal soil spring constants as part of auto-meshing. No more time consuming
error prone manual calculation of soil spring constants based on tributary
areas which change with every modification. Variable
soil support properties can be assigned.
- Powerful templates to facilitate easy model
generation
- Automated Mesh generation for maximum mesh size
- Copy, cut, paste, delete, move and replicate option
- Onscreen assignment of properties, loading and
supports
- Unlimited number of load cases.
- Right click for current element or joint information
- Modeling of slabs with openings with and with out
beams
- Releases for moment and shear for modeling Expansion
Joints and Cuts in Slabs
- Thin or thick plate bending finite elements
- Orthotropic properties may be assigned to elements
- Beam element allows for bending, torsion, shear deformations
