RE: Blast Door Design : Edge Rotation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I assume the list is text-only (no images, no attachments) to prevent 
viruses.  You would probably have to post the image somewhere else and show 
 a link.

As to reducing rotation, if you really can't support this large door leaf 
anywhere but one jamb and the head, I would go to a sandwich system with 
two plates and internal stiffeners to provide a stiffer system for similar 
weight.  Plate thickness and stiffener spacing would be a function of 
localized response of the plate and overall response affected by composite 
door thickness.

I would be interested in seeing how one determines the SDOF parameters for 
this difficult configuration of support.  We usually can design as an 
active and inactive (but operable) leaf, with a center mullion/astragal and 
 heavy throws into the sill.

Can you please let me know how to send the image to the server? I tried 
attaching the file as a pdf, the mail bounced back. I tried pasting the 
image directly to the mail, it bounced back again.
