This program can be used to calculate the statical force
distribution and eigen frequencies.

The program supports the following calculation capabilities:

- nodal loads

- seven types of beam loads: POINT LOAD, DISTRIBUTED LOAD,
TRIANGULAR LOAD, BLOCK LOAD, MOMENT LOAD, ARBITRARY DISTRIBUTED
LOAD and TEMPERATURE LOAD.

- various BASE loads from where load COMBINATIONS can be composed.

- all of a selection of the beams can possess continuous distributed
springs along the beam axis.

- the beams can be prismatic or non prismatic (incl. properties to
make possible to calculate concrete reinforcement)

- the beams can be FIXED, HINGED or SPRING connected to the nodes.

- infinite stiff EXCENTRICAL beam connections are possible.

- the nodes can undergo prescribed displacements (including
different types of supports).

- when for prismatic beams the moments of resistance have been input
the stresses in the beams will be calculated (for non prismatic
beams the moments of resistance will be calculated by the program itself).

- it is possible to indicate per beam if shear distortions should be
accounted for in the calculation process (specific important for
compact beams)

- the nodes can also be connected via springs with the surrounding world.

- the calculation of plastic hinges is supported by the program;
a rather advanced option

For non prismatic beams all options are supported as with prismatic beams
(all types of beam loads, eccentrically connections; spring connected beams,
hinges etc.).
The stiffness matrix of a non prismatic beam is determined according exact
analytical solutions.
The point load and the point moment as beam loads are also processed exactly
following analytical formulas; at non prismatic beams the other types of
beam loads are calculated by way of numerical integration (100 integration
points per load type).
For prismatic beam loads, with the exception of the arbitrary distributed
beam load, alle types of loads are processed at an exact analytical way.
