The
structural analysis of slabs is carried out by the
finite elements method (FEM). The finite elements
consist of rectangular slab pieces having 4 nodes
and a degree of freedom of 12. Loads can be
defined as point load on nods, or as linear load
between two nods ,or as uniform distributed load
on slab. It is possible to define these loads in
any phase of the project on the slab.
The
user can determine in the slab setting dialog box
the finite element width of each slab.
The
slabs are then divided up into finite elements of
such width as determined. The nods formed at the
corner points of the finite elements are numbered
by the program automatically. Now the geometrical
characteristics and the loads of the rectangular
finite elements are determined. The program solves
the equations of the system and calculates the
displacements of the nodes, and the end forces. |
