Nonlinear Support Components
- Any defined support component (rigid or elastic) can be restricted to take
only positive or negative reactions
Nonlinear Truss Members
- Truss members have the option to take only tension or
compression forces
Calculation Method
- The solution is found by iteration
- Since nonlinearly calculated results of different loadings may not be superimposed,
the program allows to combine existing loadings with arbitrary factors to get new loadings,
which can be calculated nonlinearly
- The algorithms to evaluate results for the very useful envelope specifications
generally lead to superposition of results. Since this is not allowed for nonlinear
calculations, STATIK offers the option to generate all the possible
loading combinations implied by an envelope specification and to introduce a
new envelope specification, which only compares results of combinations and thus
leads to no superposition.
