Message to any Professional Engineer or a Mechanical
Engineer, Building ManufactureR, and End User of the door!
Any manufacturer that states that the door is "freestanding" and makes any of the following claims,
you need to investigate further:
Door doesn't require "any building supports."
Door imposes no load onto the building.
Only wind load is transferred to your building.
Freestanding door with no building support.
No massive header or horizontal bracing required.
It is clear that when you study the reaction and load information...
that a tilt-up door exerts considerable loads on the building in all load cases.
Check out the reactions at the base of the columns. Technically the loads at the base of the column
are translated into the piers, not technically the building.
Check out the loads at the top of the columns.
Check out the vertical load component at the top of the columns.
Check out the horizontal component of the load into or out of the building and the vertical component
of the load.
Check out all load cases. Take into account a portion of the dead load and a portion of the two wind
loads used in any reporting.
Check out the building reaction loads when the door is in the open position. Check out the reaction loads for the four load cases when the door is in the open position.
Engineering analysis clearly demonstrates that wind conditions will result in a substantial amount
of load being applied to the building by the door.
