beams.When properly
connected,double the values for two-ply beams,
triple for three.Minimum bearing lengths shown
f
or one-ply will be the same for two-ply and
t
hree-ply.See page 15 for multiple-ply connection
details.

Values shown are the maximum uniform loads,in
p
ounds per lineal foot (plf),that can be applied to
t
he beam in addition to its own weight.

T
ables are based on uniform loads and the most
restrictive of simple or continuous spans under dry-
u
se conditions.Refer to West Fraser sizing software
f
or other loads or span configurations.

L
ateral support of beam compression edges is
required at intervals of 24” o/c or closer.

Lateral support of beams is required at bearing
locations.

WEST FRASER LVL beams are made without
c
amber;therefore,in addition to complying with
the deflection limits of the applicable building code,
o
ther deflection considerations,such as long term
deflection under sustained loads (including creep),
must be evaluated.

All 16” and 18” beam depths are to be used in
m
ultiple member units only.

To size a member for a span not shown,use
capacities for the next larger span shown.

Spans of multiple spans must be at least 40% of
adjacent span.

Bearing lengths are based on 750 psi bearing
stress for 2.0E Grade materials.Bearing stresses
cannot be increased for duration of load.
Bearing
length may need to be increased if support
member’s allowable bearing stress is less.
FLOOR BEAM SIZING:

To size a beam for use in a floor,it is necessary to
check both live load and total load.Make sure the
selected beam will work in both rows.When no live
load is shown,total load will control.Spans shown
are measured center-to-center of bearing.

Check local code for other deflection criteria.

For deflection limits of L/480 multiply loads shown
in live load row by 0.75.T
he resulting live load
shall not exceed the total load shown.
ROOF BEAM SIZING:

To size a beam for use in a roof,it is necessary to
check both live load and total load.When no live
load is shown,
total load will control.
Spans shown
are measured center-to-center of bearing.

Check local code for other deflection criteria.

Roof must have positive slope to prevent ponding.

Tables will accomodate beam slopes to a maximum
of 2:12.

beams.When properly
c
onnected,double the values for two-ply beams,triple
for three.Minimum bearing lengths shown for one-ply
will be the same for two-ply and three-ply.See page
2
7 for multiple-ply connection details.

V
alues shown are the maximum uniform loads,in
p
ounds per lineal foot (plf),that can be applied to the
beam in addition to its own weight.

Tables are based on uniform loads and the most
r
estrictive of simple or continuous spans under dry-
u
se conditions.Refer to West Fraser sizing software
for other loads or span configurations.

Lateral support of beam compression edges is
required at intervals of 24” o/c or closer.

Lateral support of beams is required at bearing
l
ocations.

W
EST FRASER LVL beams are made without camber;
therefore
,in addition to complying with the deflection
limits of the applicable building code
,other deflection
c
onsiderations,such as long term deflection under
s
ustained loads (including creep),m
ust be evaluated.

A
ll 16” and 18” beam depths are to be used in
multiple member units only.

To size a member for a span not shown,use
c
apacities for the next larger span shown.

Spans of multiple spans must be at least 40% of
adjacent span.

Bearing lengths are based on 750 psi bearing stress
for 1.8E Grade materials.Bearing stresses cannot be
increased for duration of load.
Bearing length may
need to be increased if support member’s
allowable bearing stress is less.
FLOOR BEAM SIZING:

To size a beam for use in a floor,it is necessary to
check both live load and total load.Make sure the
selected beam will work in both rows.When no live
load is shown,total load will control.Spans shown
are measured center-to-center of bearing.

Check local code for other deflection criteria.

For deflection limits of L/480,multiply loads shown in
live load row by 0.75.The resulting live load shall not
exceed the total load shown.
ROOF BEAM SIZING:

T
o size a beam for use in a roof
,
it is necessary to
check both live load and total load.When no live
load is shown,
total load will control.
Spans shown
are measured center
-to-center of bearing.

Check local code for other deflection criteria.

Roof must have positive slope to prevent ponding.

T
ables will accomodate beam slopes to a maximum of
2:12.

Lateral support of beam compression edges is required at intervals of 24” o/c or closer.

Lateral support of beams is required at bearing locations.

W
EST FRASER

L
VL beams are made without camber;therefore,in addition to complying with
the deflection limits of the applicable building code,other deflection considerations,such as long
term deflection under sustained loads (including creep),must be evaluated.

To size a member for a span not shown,use capacities for the next larger span shown.

S
pans of multiple spans must be at least 40% of adjacent span.

Bearing lengths are based on 750 psi bearing stress for 1.7E Grade materials.Bearing stresses
c
annot be increased for duration of load.
B
earing length may need to be increased if
s
upport member’s allowable bearing stress is less.
FLOOR BEAM SIZING:

T
o size a beam for use in a floor,it is necessary to check both live load and total load.Make
s
ure the selected beam will work in both rows.When no live load is shown,total load will
control.Spans shown are measured center-to-center of bearing.

Check local code for other deflection criteria.

For deflection limits of L/480,multiply loads shown in live load row by 0.75.The resulting live
l
oad shall not exceed the total load shown.
ROOF BEAM SIZING:

To size a beam for use in a roof,it is necessary to check both live load and total load.When
n
o live load is shown,total load will control.Spans shown are measured center-to-center
of bearing.

Check local code for other deflection criteria.

Roof must have positive slope to prevent ponding.

Tables will accomodate beam slopes to a maximum of 2:12.

and 16” beam depths are to be used in multiple member units only.

Tables are for one-ply 1

”beams.When properly connected,double the values for two-ply
b
eams,triple for three.Minimum bearing lengths shown for one-ply will be the same for two-ply
a
nd three-ply.See page 44 for multiple-ply connection details.

Values shown are the maximum uniform loads,in pounds per lineal foot (plf),that can be
applied to the beam in addition to its own weight.

T
ables are based on uniform loads and the most restrictive of simple or continuous spans
u
nder dry-use conditions.Refer to West Fraser sizing software for other loads or
span configurations.

Lateral support of beam compression edges is required at intervals of 24” o/c or closer.

L
ateral support of beams is required at bearing locations.

W
EST FRASER

L
VL beams are made without camber;therefore,in addition to complying with
t
he deflection limits of the applicable building code,other deflection considerations,such as long
term deflection under sustained loads (including creep),must be evaluated.

All 11
⁷∕₈
” and deeper beam depths are to be used in multiple member units only (except for
r
im board applications).

T
o size a member for a span not shown,use capacities for the next larger span shown.

S
pans of multiple spans must be at least 40% of adjacent span.

Bearing lengths are based on 600 psi bearing stress for 1.3E Grade materials.Bearing stresses
c
annot be increased for duration of load.
B
earing length may need to be increased if
s
upport member’s allowable bearing stress is less.
F
LOOR BEAM SIZING:

To size a beam for use in a floor,
it is necessary to check both live load and total load.Make
sure the selected beam will work in both rows.When no live load is shown,total load will
c
ontrol.Spans shown are measured center-to-center of bearing.

Check local code for other deflection criteria.

For deflection limits of L/480,multiply loads shown in live load row by 0.75.The resulting live
load shall not exceed the total load shown.
ROOF BEAM SIZING:

To size a beam for use in a roof,it is necessary to check both live load and total load.When
no live load is shown,total load will control.Spans shown are measured center-to-center
of bearing.

Check local code for other deflection criteria.

Roof must have a positive slope to prevent ponding.

Tables will accomodate beam slopes to a maximum of 2:12.
