General Assumptions for iLevel® Trus Joist®
Residential Beams
■
■
Lateral support is required at bearing and along the span at 24" on-center,
maximum.
Bearing lengths are based on each product’s bearing stress for applicable grade
and orientation.
■
All members 71⁄4" and less in depth are restricted to a maximum deflection of 5⁄16".
■
Beams that are 13⁄4" x 16" and deeper require multiple plies.
■
No camber.
■
■
Plank
Beams and columns must remain straight to within 5L2⁄4608 (in.) of true
alignment. L is the unrestrained length of the member in feet.
Tables on pages 8–15 include load reductions applied in accordance with code.
For applications not covered in this brochure, contact your iLevel representative.
See pages 38 and 39 for multiple-member beam connections.
Product Storage
TimberStrand ® LSL, Microllam ® LVL, and
untreated Parallam ® PSL are intended
for dry-use applications
Protect product from sun and water
CAUTION:
Wrap is slippery when wet or icy
Use support blocks at 10' on-center
to keep bundles out of mud and water

SIZING TABLES
General Notes
■
■
Tables are based on:
– Uniform loads.
– More restrictive of simple or continuous span. Ratio of short span to long span
should be greater than 0.4 to prevent uplift.
– Roof truss framing with 24" soffits.
– Exterior wall weights of 80 plf, interior 60 plf.
– Deflection criteria of L/360 live load and L/240 total load.
Tables do not consider attic loads acting concurrently with roof or snow loads.
Also see How to Use This Table on page 6 and General Assumptions on page 5.
Bearing Requirements
Tables assume minimum header support to be one trimmer (11⁄2") at each end and
41⁄2" at continuous-span supports.
(2) Minimum header support to be two trimmers (3") at each end and 71⁄2" at
continuous-span supports.
(3) Minimum header support to be three trimmers (41⁄2") at each end and 111⁄4" at
continuous-span supports.
For additional bearing information, see pages 34 and 36.

SIZING TABLES
General Notes
■
■
Table is based on:
– Uniform loads.
– More restrictive of simple or continuous span. Ratio of short span to long span
should be 0.4 or greater to prevent uplift.
– Roof truss framing with 24" soffits.
– Deflection criteria of L/240 live load and L/180 total load.
Bearing Requirements
Minimum header support to be two trimmers (3") at each end and 71⁄2" at
continuous-span supports.
(3) Requires three trimmers (41⁄2") at each end and 111⁄4" at continuous-span
supports.
Tables do not consider attic loads acting concurrently with roof or snow loads.
Also see How to Use This Table on page 8 and General Assumptions on page 5.

SIZING TABLES
General Notes
■
■
Table is based on:
– Uniform loads.
– More restrictive of simple or continuous span. Ratio of short span to long span
should be greater than 0.4 to prevent uplift.
– Roof truss framing with 24" soffits.
– Exterior wall weights of 80 plf, interior 60 plf.
– Deflection criteria of L/360 live load and L/240 total load at floor.
Bearing Requirements
Minimum header supports to be two trimmers (3") at each end and 71⁄2" at
continuous-span supports.
(3) Requires three trimmers (41⁄2") at each end and 111⁄4" at continuous-span
supports.
Tables do not consider attic loads acting concurrently with roof or snow loads.
Also see How to Use This Table on page 12 and General Assumptions on page 5.

SIZING TABLES
How to Use This Table
1. Determine appropriate Floor Load.
Floor framing length
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.
Span 1
Span 2
3. Locate Column Spacing.
4. Select beam size and material.

SIZING TABLES
General Notes
■
Bearing Requirements
Table is based on:
– Uniform loads.
– More restrictive of simple or continuous beam span. Ratio of short span to
long span should be greater than 0.4 to prevent uplift.
– Deflection criteria of L/360 live load and L/240 total load.
Minimum beam supports to be two trimmers (3") at each end and 71⁄2" at
continuous-span supports.
(3) Requires three trimmers (41⁄2") at each end and 111⁄4" at continuous-span
supports.
Also see How to Use This Table on page 14 and General Assumptions on page 5.

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 with 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).
– More restrictive of simple or continuous span.
– Deflection criteria of L/240 total load (TL) and L/360 live load (LL).
For live load deflection limits of L/240 or L/480, multiply Live Load L/360
values by 1.5 or 0.75, respectively. The resulting live load may 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
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 with a capacity that
exceeds actual total and live loads.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 19.

FLOOR LOAD TABLES
General Notes
■
■
Table is based on:
– Uniform loads (beam weight considered).
– More restrictive of simple or continuous span.
– Deflection criteria of L/240 total load (TL) and L/360 live load (LL).
For live load deflection limits of L/240 or L/480, multiply Live Load L/360
values by 1.5 or 0.75, respectively. The resulting live load may 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
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 with a capacity that
exceeds actual total and live loads.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 21.

FLOOR LOAD TABLES
General Notes
■
■
Table is based on:
– Uniform loads (beam weight considered).
– More restrictive of simple or continuous span.
– Deflection criteria of L/240 total load (TL) and L/360 live load (LL).
For live load deflection limits of L/240 or L/480, multiply Live Load L/360
values by 1.5 or 0.75, respectively. The resulting live load may 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 with 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).
– 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 with 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
General Notes
■
Table is based on:
– Uniform loads (beam weight considered).
– 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 24 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 with 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).
– 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 with 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).
– 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
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 with a capacity that
exceeds actual total load.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 31.

NON-SNOW ROOF LOAD TABLES
General Notes
■
Table is based on:
– Uniform loads (beam weight considered).
– 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 with 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).
– 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 32 and General Assumptions on page 5.

General Notes
■

■
Use specific gravity of 0.5 when designing lateral connections.
■
■
■
■
NDS®
2005 or manufacturer’s code report.
300 PLF
415 PLF
Values listed are for 100% stress level. Increase 15% for snow-loaded roof
conditions or 25% for non-snow roof conditions, where code allows.
Bold Italic cells indicate Connector Pattern must be installed on both sides.
Stagger fasteners on opposite side of beam by 1⁄2 the required Connector
Spacing.
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.
First, check the allowable load tables on pages 16–33 to verify that three
pieces can carry the total load of 715 plf with proper live load deflection
criteria. Maximum load applied to either outside member is 415 plf. For a
3-ply, 13⁄4" assembly, two rows of 10d (0.128" x 3") nails at 12" on-center
is good for only 280 plf. Therefore, use three rows of 10d (0.128" x 3")
nails at 12" on-center (good for 415 plf).
Alternatives:
Two rows of 1⁄2" bolts or 1⁄4" x 31⁄2" SDS screws at 19.2" on-center.

Hanger information on these two

Simpson Strong-Tie® or
USP Structural Connectors ®.
For additional information,
please refer to their literature.
(1) Value may be increased for duration of load.
General Notes
■
■
Hanger capacity may be more or less than that of the supported member;
therefore, check both the hanger and the beam capacities.
Leave 1⁄16" clearance (1⁄8" maximum) between the end of the beam or header and
its support member or hanger.
Header Assumptions
■
■
When using top mount hangers in back-to-back applications, ensure that the
supporting beam width is adequate to prevent hanger interference.
Face mount hangers to be supported by 1¾" width headers, minimum.
Nailing Requirements
■
Hangers to be supported by headers of TimberStrand® LSL, Microllam® LVL,
Parallam® PSL, Douglas fir, southern pine, or spruce-pine-fir.
40
■
Fill all round and positive-angle nail holes with the proper nails.
– 10d x 11⁄2" nails are 0.148" dia. by 11⁄2" long.
– 10d nails are 0.148" dia. by 3" long.
– 16d nails are 0.162" dia. by 31⁄2" long.
– For USP: 16d R.S. nails are (9 gauge) 0.148" dia. by 31⁄2" long ring-shank nails.

Tables are based on:
– Solid, one-piece column members used in dry-service conditions.
– Bracing in both directions at column ends.
– NDS® 2005.
– Compression perpendicular-to-grain stress of 400 psi adjusted per the
NDS® 2005, 3.10.4.
– Simple columns with axial loads only. For side loads or other combined
bending and axial loads, see the NDS® 2005.
Allowable loads have been adjusted to accommodate the worst case of the
following eccentric conditions: 1⁄6 of column thickness (first dimension) or 1⁄6 of
column width.
Two 16d (0.162" x 31⁄2") nails for every
13⁄4" of column width, nailed through
the plate into the column
Beams and columns must remain straight to within 5L2⁄4608 (in.) of true
alignment. L is the unrestrained length of the member in feet.
For column allowable design stresses see page 5.

In order to use the manufacturer’s
published capacities when designing
column caps, bases, or holdowns for
uplift, the bolts or self-drilling screws
must be installed perpendicular to the
wide face of strands as shown at left.
DO NOT install bolts or
screws into the narrow
face of strands

Capacities shown cannot be adjusted for duration of load.
Connector capacities assume a beam material with a minimum perpendicularto-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.
Other connectors may be available. Capacities may vary depending on
orientation of member. Contact the hanger manufacturer for more information.
