We provide hints and tips to help you get started with the main programs RFEM and RSTAB.
How are the signs of the member internal forces, for example the moments, defined in RFEM/RSTAB?
The bending moment My is positive if tensile stresses occur at the positive member face (in direction of the z-axis).
Mz is positive if compressive stresses occur at the positive member face (in direction of the y-axis).
The sign definition for torsional moments, axial forces, and shear forces conforms to the usual conventions:
These internal forces are positive if at the positive face they act in the positive direction.
