-simply supported in the vertical (//y//) direction the at gusset plate - lower flange intersection nodes (''support_me'' node set).
-kN load, uniformly distributed along the intersection line between the upper flange and the web spanning from support to supports (''load_me'' node set).
-Please note that in MSC.Marc the supplied point load value is applied to **each** associated node.
-Evaluate the peak equivalent von Mises stress along the structure according to the linear elastic modeling.
-Due to the compressive state of the profile web, a check with respect to buckling is also required.
