"Controlling Analysis Loads" in FBD tab

(1/1)

hunterqiu:
An uniaxial stiffened panel is only loaded by Nx with B.C. "Simple", but the design-to load Mx is gotten in "Controlling Analysis Loads".
From my understanding, loaded by uniaxial load with simple B.C., there is no Mx reaction.  Is it correct, my parameters' setting?

jjainswo:
This is correct.  HyperSizer is computing the virtual loads in 3 places at the two adjacent edges and the center of the panel.  You are correct assuming there will be no Mx at the edge in a simply supported uniaxial panel but there will be a virtual Mx in the center since the simple BC on the edges is constraining longitudinal displacement.
