Door Specification 1

[Jandra11]

I asked to check if the door is structurally safe. Is there any specific code/specs in designing Doors? What are the things need to check except for the support and mainframe? All opinion/input will be very much appreciated. Thank you in advance.

Jandra11, this sounds like someone is trying to keep you busy. What loads are you supposed to check for? Wind? Impact? Seismic? Doors are more appropriately qualified by testing than analysis. There's a lot of manufactured items (hinges; strikes; etc.), tough to quantify items (spot welds of skin to reinforcing) and materials that just tough to check (the reinforcing ribs for doors might or might not have properties). Or if they use Schlage hardware, the answers might be different than for Kwik Set.
In Florida, they have testing protocols for doors subject to high winds or impacts. Analysis is limited to anchorage of the frame to the structure.

Doors sold commercially must generally satisfy testing criteria. I'd start by looking at ASTM E330 and ASTM F2247.

Is this some type of huge door for, say, a bank vault or the main entrance to a public assembly hall, or the like? Or is it a regular door being mass-produced? If it's the later it sounds like kipfoot may have steered you in the right direction. Shoot, maybe if it's the former as well. I'm just curious about the application.

About the only "structurally safe" criteria for a door could be "Would it still open after an earthquake to allow emergency exit?"

And you fight two requirements: If it were "functionally safe" (against theft or terrorism or break in and air leakage when closed) then it could be jammed into the sill and frame (and unable to be opened from the inside!) after an earthquake; but if it could always be hammered through or wedged open regardless of how the frame moved and distorted , then it would leak air in/out and would not resist theft and break ins.

thank you all for the response.
I worked in an architectural company that produce different kinds of furniture/balustrade etc. And they want me to create a calculation report on every item even on a wooden counter.
BTW the door(wood w/ steel cladding) is a 2 leaf door with 4mx2m dimension and have an acrylic glass(6mm thick 2400mmx800mm) in the middle of the leaf. Base on British standard glass used in doors 1500mm above FFL should be consider safety glass. Does acrylic glass considered a safety glass because as far as I know there are only 3 kinds of safety glass namely wired glass,laminated and tempered or did I miss something.
@Jed maybe you are right. I agree that analysis is only limited to the anchorage only but they asking me if the section of the wood, connection of glass to wood, thickness of the glass.
@kip thank you for input
@archie its huge compare to ordinary door and it have some decoration(glass,perforated sheet) for the meantime I used 2 analysis. one assuming the door as a barrier when it is closed and .5kn at @ top free edge of the door when its open.
@racookpe i just consider imposed live load here just to make the analysis simple. or is there any specific code how to design a door?
