Designer should check the deflection of the diaphragm.
Roof deck deflection.
Commentary the adequacy of deck edge support details should be revised.
Deflection of the deck shall not exceed l 240 under the uniformly distributed design live load.
The insurance fire rating or wind uplift requirements of a building may not allow a substitutionof fasteners or change inspacingasgoverned by design.
Allowable deflection is generally expressed as a fraction of the span in inches.
Structural decking also known as roof decking should not be confused with lumber intended for residential and non residential outdoor decks.
Other innovations include n 32 a 32 wide 3 deep roof deck panel and our new smooth series rivet attachment for our portfolio of cellular deck products.
2 deep roof deck and has since replaced the previous industry standard 36 5 and 36 7 attachment patterns.
All spans are to be considered center to center of supports.
Specifically roof decks subjected to gravity loading dead live or snow and wind uplift loading can be analyzed using either asd or lrfd methods.
First to the west coast market our new smooth series rivet attachment offers a.
Bending stresses as well as deflections are checked.
Standard structural decking patterns are 2 nominal tongued and grooved t g and 3 and 4 double t g products available with vee or eased edges to meet discriminating architectural requirements.
Deflection is the bending or sag caused by loading.
The amount of flex depends on the magnitude of the load applied span of the member and stiffness of the member.
