Side Loaded Beams
Where oor joists are joined to the side of the beam (typically using a joist hanger), this load chart must be used
to establish the proper pattern based on the design load as determined by the engineer and noted on the plans.

1) Allowable loads are derived from tested fastener values as reported in ICC-ES ESR-2761.
2) The uniform loads in this table relate only to the capacity of the fastener to transfer shear loads between plies.
The specific gravity (SG) and the capacity of the EWP should be verified with manufacturer's literature.
3) Values listed reflect 100% load duration. (C
D
=1.0) The designer may apply adjustment factors to increase or decrease
these loads per the NDS based on conditions for each assembly.
4) Load values depicted assume all uniform load is applied to the outermost ply or point of entry for the screw.
5) To minimize rotation, 7" wide beams shall be side loaded only when loads are applied to both sides of the beam
with the lesser loaded side bearing at least 25% of the overall design load.
6) Tip side loading to beam is allowed for 50% of listed allowable head side load. Head side and tip side of beam can be
loaded concurrently so long as they do not exceed 150% listed head side capacity.(Example: A 3-ply assembly with a head side load
of 1,200 plf and tip side load of 600 plf may be fastened together with 3 rows of WSWH5 screws at 16" O.C. spacing
between fasteners in a row).
