A typical bay of a composite floor system is illustrated in below. Select an
appropriate ASTM A992 W-shaped beam and determine the required number of w-
in.-diameter steel headed stud anchors. The beam will not be shored during
construction.
Beam to be
designed
7%" total depth normal
weight slab on 18 gage
composlte deck
A
45'-0"
Plan
Section A-A
To achieve a two-hour fire rating without the application of spray applied fire
protection material to the composite deck, 4 1/2 in. of normal weight (145 lb/ft')
concrete will be placed above the top of the deck. The concrete has a specified
compressive strength, f. = 4 ksi.
Applied loads are as follows:
Dead Loads:
Pre-composite:
= 75 lb/ft2 (in accordance with metal deck manufacturer's data)
Self-weight = 5 lb/ft2 (assumed uniform load to account for beam weight)
Slab
Composite (applied after composite action has been achieved):
Miscellaneous
= 10 lb/ft? (HVAC, ceiling, floor covering, etc.)
Live Loads:
Pre-composite:
Construction
= 25 lb/ft? (temporary loads during concrete placement)
Composite (applied after composite action has been achieved):
= 100 lb/ft? (assembly occupancy)
Non-reducible
3@ 10-0" = 30-0".
