SIZING TABLES Floor framing length

How to Use This Table Span 1 Span 2

1. Determine appropriate Floor Load.
2. Find the Floor Framing Length that meets or exceeds the sum of Spans 1 and 2

for the supported floor joists. When floor joists are continuous span, span 1 or 2
cannot be less than 40% of the Floor Framing Length. If floor joists are simple
span (not continuous over the beam), then the Floor Framing Length may be
taken as 80% of span 1 plus span 2.
3. Locate Column Spacing.
4. Select beam size and material.

General Notes SIZING TABLES

 Table is based on: Bearing Requirements
– Uniform loads. Minimum beam supports to be 2 trimmers (3") at each end and 71⁄2" at
– More restrictive of simple or continuous beam span. Ratio of short span to continuous-span supports.
long span should be greater than 0.4 to prevent uplift. (3) Requires 3 trimmers (41⁄2") at each end and 111⁄4" at continuous-span supports.
– Deflection criteria of L/360 live load and L/240 total load.

FLOOR LOAD TABLES

How to Use This Table

1. Calculate total and live load (neglect beam weight) on the beam or header in
pounds per linear foot (plf).

2. Select appropriate Span (center-to-center of bearing).
3. Scan horizontally to find the proper width and a depth which has a capacity that

exceeds actual total and live loads.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 17.

FLOOR LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/240 total load and L/360 live load.

 For live load deflection limits of L/240 or L/480, multiply live load values by
1.5 or 0.75, respectively. The resulting live load shall not exceed the total load
shown.

Also see How to Use this Table on page 16 and General Assumptions on page 5.

FLOOR LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/240 total load and L/360 live load.

 For live load deflection limits of L/240 or L/480, multiply live load values by
1.5 or 0.75, respectively. The resulting live load shall not exceed the total load
shown.

Also see How to Use This Table on page 18 and General Assumptions on page 5.

FLOOR LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/240 total load and L/360 live load.

 For live load deflection limits of L/240 or L/480, multiply live load values by
1.5 or 0.75, respectively. The resulting live load shall not exceed the total load
shown.

Also see How to Use This Table on page 20 and General Assumptions on page 5.

SNOW ROOF LOAD TABLES

How to Use This Table

1. Calculate total load (neglect beam weight) on the beam or header in pounds per
linear foot (plf).

2. Select appropriate Span (center-to-center of bearing).
3. Scan horizontally to find the proper width and a depth which has a capacity that

exceeds actual total load.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 23.

SNOW ROOF LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/180 total load. For stiffer deflection criteria, use L/240
values for total load deflection.

 For door and window applications, iLevel recommends using the L/360
value for a live load deflection limit and the L/240 value for a total load
limit.

Also see How to Use This Table on page 22 and General Assumptions on page 5.

SNOW ROOF LOAD TABLES

How to Use This Table

1. Calculate total load (neglect beam weight) on the beam or header in pounds per
linear foot (plf).

2. Select appropriate Span (center-to-center of bearing).
3. Scan horizontally to find the proper width and a depth which has a capacity that

exceeds actual total load.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 25.

SNOW ROOF LOAD TABLES

How to Use This Table

1. Calculate total load (neglect beam weight) on the beam or header in pounds per
linear foot (plf).

2. Select appropriate Span (center-to-center of bearing).
3. Scan horizontally to find the proper width and a depth which has a capacity that

exceeds actual total load.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 27.

SNOW ROOF LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/180 total load. For stiffer deflection criteria, use L/240
values for total load deflection.

Also see How to Use This Table on page 26 and General Assumptions on page 5.

NON-SNOW ROOF LOAD TABLES

How to Use This Table

1. Calculate total load (neglect beam weight) on the beam or header in pounds per
linear foot (plf).

2. Select appropriate Span (center-to-center of bearing).
3. Scan horizontally to find the proper width and a depth which has a capacity that

exceeds actual total load.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 29.

NON-SNOW ROOF LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/180 total load. For stiffer deflection criteria, use L/240
values for total load deflection.

 For door and window applications, iLevel recommends using the L/360
value for a live load deflection limit and the L/240 value for a total load
limit.

Also see How to Use This Table on page 28 and General Assumptions on page 5.

NON-SNOW ROOF LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/180 total load. For stiffer deflection criteria, use L/240
values for total load deflection.

Also see How to Use This Table on page 30 and General Assumptions on page 5.

NON-SNOW ROOF LOAD TABLES

How to Use This Table

1. Calculate total load (neglect beam weight) on the beam or header in pounds per
linear foot (plf).

2. Select appropriate Span (center-to-center of bearing).
3. Scan horizontally to find the proper width and a depth which has a capacity that

exceeds actual total load.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 33.

NON-SNOW ROOF LOAD TABLES

General Notes

 Table is based on:
– Uniform loads (beam weight considered) and the more restrictive of simple or
continuous span.
– Deflection criteria of L/180 total load. For stiffer deflection criteria, use L/240
values for total deflection.

Also see How to Use This Table on page 32 and General Assumptions on page 5.

General Notes Multiple-Member Connection Example

 Connections are based on NDS® 2001. 300 PLF 420 PLF

 Use specific gravity of 0.5 when designing lateral connections. First, check the allowable load tables on pages 16-33 to verify that 3
pieces can carry the total load of 720 plf with proper live load deflection
 Values listed are for 100% stress level. Increase 15% for snow-loaded roof criteria. Maximum load applied to either outside member is 420 plf. For a
conditions or 25% for non-snow roof conditions, where code allows. 3-ply 13⁄4" assembly, 2 rows of 10d (3") nails at 12" on-center is good for
only 280 plf. Therefore, use 3 rows of 10d (3") nails at 12" on-center (good
 Bold Italic cells indicate Connector Pattern must be installed on both sides. for 420 plf).
Stagger fasteners on opposite side of beam by 1⁄2 the required Connector Alternates:
Spacing. 2 rows of 1⁄2" bolts or SDS 1⁄4" x 31⁄2" screws at 19.2" on-center.

 Verify adequacy of beam in allowable load tables on pages 16–33.

 7" wide beams should be side-loaded only when loads are applied to both sides
of the members (to minimize rotation).

 Minimum end distance for bolts and screws is 6".

 Beams wider than 7" require special consideration by the design professional.

38 iLevel Trus Joist® Beam, Header, and Column Specifier’s Guide TJ-9000 September 2006

MULTIPLE-MEMBER CONNECTIONS FOR TOP-LOADED BEAMS

13⁄4" Wide Pieces:

 Minimum of 3 rows of 10d (0.128" x 3") nails at 12" on-center.
 Minimum of 4 rows of 10d (0.128" x 3") nails at 12" on-center for 14" or deeper.
 If using 12d–16d common nails, the number of nailing rows may be reduced

by one.
 Load must be applied evenly across entire beam width. Otherwise, use

connections for side-loaded beams.

31⁄2" Wide Pieces:

 Minimum of 2 rows of 1⁄2" bolts at 24" on-center, staggered.

L6 Multiple pieces can be nailed or bolted together to form a header or

 Fill all round and positive-angle nail holes with the proper nails.
 Hanger capacity may be more or less than that of the supported member; – 10d x 11⁄2" nails are 9 gauge (0.148" diameter) by 11⁄2" long.
therefore, both the hanger and the beam capacities must be checked. – 10d nails are 10d common (0.148" diameter) by 3" long.
– 16d nails are 16d common (0.162" diameter) by 31⁄2" long.

– Solid, one-piece column members used in dry-service conditions.
– Bracing in both directions at column ends.
– 425 psi for plate bearing.
– NDS® 2001.

 Allowable loads accommodate axial loads only with 1⁄6 column width/thickness
eccentricity.

For column allowable design stresses see page 5.

Two 16d (31⁄2") common nails for
every 13⁄4" of column width, nailed
through the plate into the column

General Notes

 Capacities shown cannot be adjusted for duration of load.

 Connector capacities assume a beam material with a minimum perpendicular-to-grain bearing of 625 psi.

 Connector capacities may be more than the column capacity; therefore, check both the connector and the
column capacity and use the lower capacity.
