Calculation

RSTAB

RSBUCK

Which calculation methods are used in RSTAB and RSBUCK?

Answer

RSTAB is a FEM program that uses trigonometric trial functions for members. For this reason, it is not necessary to divide the members to obtain sufficiently accurate results and the calculation speed is higher accordingly.

RSBUCK determines the eigenvalues of the stiffness matrix and can thus linearly calculate the critical load and buckling mode of the structure.
