Structural Aluminium Calcs Sliding Folding Door
Structural Aluminium Calcs Sliding Folding Door
(OP)
Dear all,
I have just started to produce structural calcs for aluminium extrusion profiles for doors/openings.
I have an issue with a sliding folding door.
I'm using the Ireq formula for a fixed-fixed beam with UDL.
The door slides on top and bottom, and has two hinges intermediate that holds it to the adjacent door.
Should I be desigining with a fixed-pinned-pinned-fixed?
fixed(sliding)-------hinge------hinge-----fixed(sliding)
Any views/comments would be much appreciated.

Aluminum is a terrible bearing material.
Common 'sliding' aluminum doors have small rollers concealed at the 'sliding' surfaces.
