Notes
  • Reactions for a portal frame with pinned bases and a uniformly distributed load on the beam.
  • The bases are pinned, so the bending moment there is 0. The value shown is MB = Hh, at the column top.
  • The stiffness ratio k = K2/K1 compares the stiffness of the beam with that of the column.
