We have been in contact with Vulcraft and cannot seem to find the right person to help with this. Does anyone have any ideas on how to obtain a copy of this reference, or any other reference that discusses the design of a 3 sided metal deck diaphragm?
Thanks to all for your responses.
I'm assuming you are suggesting that the flexibile diaphragm be designed assuming it can transmit the resulting torsion to the bracing elements in perpendicular direction to the load. Have you seen any documentation like published examples regarding designing flexible diaphragms like this...
Flexible as defined by Steel Deck Institute relating to diaphragm stiffness. Normally metel deck diaphragms end up on the flexible side where concrete roofs are on the rigid end of things.
It has been my experience that flexible diaphragms cannot resist torsion and distribute shear loads...
We are currently designing a retail building that cannot use any braced frames along an entire front side of the building and the owner wants to stay away from moment connections because of cost. Can anyone point me to a reference regarding how to design a 3 sided metal deck flexible diaphragm...
