Manufactured Floor Systems ..

...

Print this out (link below), maybe take a look at beforehand, and bring to class on Monday. 

Good stuff!  Where possible I let the Manufacturer `design' the floor system. 

Much of what is in it should be making more and more sense ...

`Uniform and Predictable' ...

Design Properties, p. 3 ... Allowable Moment, Shear, and End Reaction ... these are basically like Allowable stresses multiplied by section properties (or contact area, for bearing).

Note the 100% load duration ... this is like our C_D for `Normal' Load duration (Occupancy Live load) ...

Note that design values CANNOT be increased by the repetitive use factor (footnote 1 to table on p. 3).  (Anyone wanna take a shot at why?!!!)

Note the 2-term deflection equations I told you about ... the second term being for shear deflection.

Note that deflection equations are units-dependent.

Note that S and I are NOT published. :) 

p. 4 ... and beyond ... Span Tables ...

Live load ... deflection limits, etc.

Cool Material Weights info on right side of p. 4 ...

p. 5 ... Load Table ...

p. 6 ... What a `System' looks like ... and the `ingredients' ...

p. 7, and beyond ... Details

p. 9 Allowable HOLES ... woohoo!

Other stuff ...

Roof framing, starting p. 13 ...

And then connectors ...
