General beam-column stiffness connections and the full-welded dog skeleton connection is analyzed and compared by Nonlinear finite element analysis method (ANSYS method) and draw some conclusions.

This method can not only be used to draw shear force diagram quickly, but also to determine the shear sign automatically, and to verify the reaction force of multi-span beam.

This program can complete the designing and checking of a two-span continuous steel crane beam, and it can also draw of internal force envelopes and output the calculation files.
