Allowable Deflection for Large Glazed Patio Facade
Allowable Deflection for Large Glazed Patio Facade
(OP)
Hello All:
Wondering what value do you guys use for something like this. Customer wants a very large area glazed facing his rear yard. He wants the header above doors the skinniest possible. I am running some quick frame FEA with SAP. What allowable out of plane deflection you use. There will be three doors 12'x7'. I am in the neighborhood of 350 sf of glass. Wind is estimated at 17 psf (South central Texas, not hurricane area). I am framing with 4'' HSS cols and light W shapes for beams.
Thanks,

Keep in mind that table 1604.3 of the 2009 IBC has L/240 for Wind loads for exterior walls with brittle finishes. I wouldn't go that low, but worth keeping in the back of your mind.

Thanks for your reply. I had this L/600 on the back of my head and L/240 I agree, is really low even for tempered glass. Door manufacturer is Andersen,so I think is fine on that side. Really appreciate your feedback.
