how

deal

with

perimeters.

However,

this

uncommon

case

may

be
...
...
within

as

- would
...
- following
...
- a
...
- hand-calculation
...
- approach.
...
- Use statics to replace the loading within both columns with equivalent loads and moments located at the centroid of the composite section.
- SAFE will then check the punching-shear perimeter of the total composite section. Here, results will align with general practice.
