Diamond Plate Deflection Requirement?
Diamond Plate Deflection Requirement?
(OP)
Is anyone aware of any code mandated defelection restrictions for diamond plate (raised pattern floor)? AISC Table 3-18a limits deflection to L/100 which results in an extremly low allowable load. I am analyzing a few existing industrial mezzanines to determine an appropriate load rating them. I am working in the US and governed by IBC and ASCE 7.

For access platforms you may be able to use a lower deflection limit than L/100, but that in my opinion is already fairly low.

Stick closely to the code numbers,,

Personally, I'd use something more strict than the L/100 for the supporting members, probably a minimum of L/120 for D + L and L/180 for L, and maybe considering using L/180 and L/240...

How is the deck plate supported?
How are you determining deflections?
Simple beam approach is super conservative
