GENERAL INFORMATION
General
Presented in these load tables are maximum uniformly
distributed specified loads.
Limit States Design (LSD)
Strength - Limit States Design principles were used in
the development of the load tables in accordance with
CSA-S136-01, North American Specification for the
Design of Cold Formed Steel Structural Members and
the National Building Code of Canada,. The factored
resistance under consideration, φR, must be equal to or
greater than the effect of the factored loads, i.e.,
φ R ≥ Effect of Factored Loads.
Hence, a short calculation must be carried out to
compute the specified live load. See example.
Serviceability – Maximum specified deflection loads
given in the tables must be compared with their
respective specified live loads.
Steel
Specification - Conforms to ASTM A653M grade
230; Yield strength 230 MPa (33 ksi) and tensile
strength of 310 MPa (45 ksi).
Finishes – ZF 075 (A25) or Z275 (G90). For heavier
galvanizing, refer to ASTM A653-A653M.
Design Considerations
Strength - The maximum uniformly distributed
specified load obtained from the load table must be
equal to or greater than (Specified live load + 0.833
times the specified dead load).
Where 0.833 = 1.25/1.5.
Conservative Strength Approach - The maximum
uniformly distributed specified load obtained from the
load table must be equal to or greater than (Specified
live load + specified dead load).
EXAMPLE
1 1/2” DECK (IMPERIAL)
Given:
Triple span continuous, L = 8 ft each span
Deck thickness, t = 0.030 in
L/180 deflection limit (data in tables are based on
L/240)
Bearing length, n = 2 in.
Specified loads
1) Dead loads (DL)
a) deck
1.6 psf
b) superimposed
8.2 psf
DL = 9.8 psf
2) Live load (LL)
LL = 40 psf
Solution:
Strength
1) Specified loads
[LL + 0.833 DL]
[40 + 0.833 (9.8)] = 48.2 psf
2) Maximum specified load (from Table under “S”)
is 50 psf
Since 50 > 48.2 ∴ ΟΚ
3) Check end web crippling (n = 2 in.)
a) Specified end reaction
0.400(48.2)8.0 = 154 lb/ft
b) Maximum specified end reaction
(from Section Property Table)
Pe = Pe1 + Pe2 n / t
Pe = 174 + 43.5 2 / 0.030 = 529 lb/ft
Since 529 > 154 ∴ ΟΚ
4) Check interior web crippling (n = 2 in.)
a) Specified interior reaction
1.10(48.2)8.0 = 424 lb/ft
b) Maximum specified interior reaction
Pi = Pi1 + Pi2 n / t
Pi = 305 + 51.9 2 / 0.030 = 729 lb/ft
Since 729 > 424 ∴ ΟΚ
Web Crippling Check – If n/t > 210, use n/t = 210.
Serviceability (Deflection) – The effective moment of
inertia for deflection determination has been calculated
at an assumed specified live load stress of 0.6Fy.
Deflection
From Table under “D” (L/240) = 42 psf
For L/180, multiply 42 by 240/180 = 56 psf.
Since 56 is > 40 ∴ ΟΚ

GENERAL INFORMATION
General
Steel
Where 0.833 = 1.25/1.5.
EXAMPLE
3” ROOF DECK (IMPERIAL)
Given:
Two-span continuous, L = 12 ft each span
Deck thickness, t = 0.036 in
L/240)
Bearing length, n = 3 in. (n/t = 83.3)
Specified loads
1) Dead loads (DL)
a) deck
2.6 psf
b) superimposed
8.2 psf
DL = 10.8 psf
2) Live load (LL)
LL = 40 psf
Solution:
Strength
1) Specified loads
[LL + 0.833 DL]
[40 + 0.833 (10.8)] = 49.0 psf
is 52 psf
Since 52 > 49.0 ∴ ΟΚ
3) Check end web crippling (n = 3 in.)
0.375(49.0)12 = 221 lb/ft
Pe = 216 + 54.0 3 / 0.036 = 709 lb/ft
Since 709 > 221 ∴ ΟΚ
4) Check interior web crippling (n = 3 in.)
1.25(49.0)12 = 735 lb/ft
Pi = 409 + 69.5 3 / 0.036 = 1043 lb/ft
Since 1043 > 735 ∴ ΟΚ
Deflection
From Table under “D” (L/240) = 88 psf
For L/180, multiply 88 by 240/180 = 117 psf.
Since 117 is > 40 ∴ ΟΚ

EXAMPLE
76 mm (3”) DECK (METRIC)
Given:
Triple span continuous, L = 3.8 m each span
Deck thickness, t = 0.914 mm
L/240)
Bearing length, n = 60 mm (n/t = 65.6)
Specified loads
1) Dead loads (DL)
a) deck

Solution:
Strength
1) Specified loads
[LL + 0.833 DL]
[2.0 + 0.833 (1.0)] = 2.83 kPa
is 2.89 kPa
Since 2.89 > 2.83 ∴ ΟΚ
3) Check end web crippling (n = 60 mm)
0.400(2.83)3.8 = 4.30 kN/m
Pe = 3.18 + 0.796 60 / 0.914 = 9.63 kN/m
Since 9.63 > 4.30 ∴ ΟΚ
4) Check interior web crippling (n = 60 mm)
1.10(2.83)3.8 = 11.8 kN/m
Pi = 6.04 + 1.03 60 / 0.914 = 14.4 kN/m
Since 14.4 > 11.8 ∴ ΟΚ
Deflection
From Table under “D” (L/240) = 2.95 kPa
For L/180, multiply 2.95 by 240/180 = 3.93 kPa
Since 3.93 is > 2.0 ∴ ΟΚ

TECHNICAL NOTES
Material Properties
1. The composite steel deck ICD-150 is the IRD-150
roof deck with embossments rolled into the web
elements to achieve the composite interlocking
capacity between the steel deck and concrete.
2. Steel deck section properties were calculated in
accordance with CSA S136-01 (Supplement 2004).
3. Steel conforms to ASTM A653 SS Grade 33 and
A653M SS Grade 230 with Z275 (G90) and ZF75
(A25) surface coatings.
4. Concrete is based on normal density of 2300
3
kg/m (145 pcf) and having a minimum
compressive strength of 20 MPa (3 ksi).
Load Tables
1. Loads are maximum specified uniformly
2.

distributed loads resulting from human occupancy
and should not be used for concentrated loads.
Maximum specified load from load table must be
≥ [LL + 0.833DL];
Where LL = specified live load;
DL = specified dead load; 0.833 = 1.25/1.5
Loads greater than 10 kPa (200 psf) are commonly
the result of large concentrated moving loads.
In such cases, appropriate design consideration
should be used by the structural engineers.
The ICD-150 steel deck provides the positive
reinforcement for the simply supported composite
slab and no additional reinforcing steel is required.
To control shrinkage and temperature cracking,
a minimum steel wire mesh of 152 x 152 –
MW9.1/MW9.1 (6 x 6 - 10/10) is recommended as
per CSSBI S3-03.
Shoring requirements shown in shaded areas of
the load table were established in accordance with
CSSBI 12M-06.
To establish the shear-bond capacity of the
composite slab system, laboratory tests were
carried out at the Structural Testing and Research
laboratory (STAR), Cambridge, Ontario in
accordance with CSSBI S2-02.
All technical information and load tables were
prepared by Dr. R.M. Schuster, Professor
Emeritus of Structural Engineering, University of
Waterloo, Ontario.
EXAMPLE (Imperial)
Determine the specified uniformly distributed live load
that can be placed on the composite floor slab, given
the following information:
Given:
•
•
•
•
•
•
Steel deck thickness = 0.048 in.
Yield strength = 33 ksi
3
Normal density concrete = 145 lb/ft
Overall slab depth = 4.5 in.
Double span, each = 10 ft
Specified superimposed dead load,
DL = 32 psf
Solution:
The maximum specified load in (psf) from load table
must be ≥ [LL + (1.25/1.5)DL],
where
LL = specified live load
DL = specified superimposed dead load
From load table under 10 ft span, the maximum
specified load is 259 psf, therefore,
259 ≥ [LL + (1.25/1.5)32] and solving for LL,
LL = 232 psf
Since this is in the shaded area, one shore support is
required at mid-span in each span.
Note:
-The self-weight of the steel deck and concrete slab
have already been accounted for in the maximum
specified uniformly distributed load given in the
composite slab load table.
-Minimum Bearing Length “n” at end support is
1.5 x height of deck = 2.25”.
-At middle support use n=4”.

EXAMPLE (Metric)
Given:
•
•
•
•
•
•
Steel deck thickness = 1.22 mm
Yield strength = 230 MPa
3
Normal density concrete = 2300 kg/m
Overall slab depth = 120 mm
Double span, each = 3.0 m
DL = 1.55 kPa
Solution:
The maximum specified load in (kPa) from load table
must be ≥ [LL + (1.25/1.5)DL],
where
From load table under 3.0 m span, the maximum
specified load is 13.8 kPa, therefore,
13.8 ≥ [LL + (1.25/1.5)1.55] and solving for LL,
LL = 12.5 kPa
Note:
1.5 x height of deck = 57mm
-At middle support use n=100mm.

1.5 x height of deck = 114mm.
Acoustic roof deck is designed to serve as a sound-absorbing ceiling or an interior wall cladding
(e.g. school gymnasium, training facilities, airports and others) while maintaining most of its
structural properties. Using the IRD-150 and IRD-151 load table, the designer is urged to reduce the
vertical load resistance by 5%. The webs of the roof deck are perforated with 1/8” (3mm) diameter
holes staggered 3/8” (9.53mm) on center.
The sound reduction is achieved by fibreglass strips placed between the perforated webs. These
strips can be supplied by Ideal Roofing and are available as a special order.
IRD-150 and IRD-151 Acoustic Deck is available in 22 gauge (0.030”/0.762mm), 20 gauge
(0.036”/0.914mm) and 18 gauge (0.048”/1.219mm) in galvanized G90 (Z275), galvanized G60
