Input
Column height
Span length
Second moment of area of the column
Second moment of area of the beam
Distributed load

Stiffness of the beam

Bending moment at column top
Bending moment at beam midspan
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.
