Pinned base, distributed load on the column
Input
Column height
Span length
Second moment of area of the column
Second moment of area of the beam
Distributed load on the column
Result
Stiffness of the column
Stiffness of the beam
Stiffness ratio
Vertical reaction
Horizontal reaction (loaded side)
Horizontal reaction (opposite side)
Notes
- Reactions for a portal frame with pinned bases and a distributed load on the column.
- The distributed load w acts horizontally over the whole height of the left-hand column.
- H_A is the horizontal reaction on the loaded side (left) and H_D on the far side (right), and H_A + H_D = wh.
