Allowable Load Reference
Tables
for Better Header® Beam Selection
Beam spans are defined as follows: Simple span dimensions are measured from the
inside face of the support and Multiple span dimensions
are measured from the inside of the face of your exterior
support to the center line of the interior support.
These tables for simple spans (with support at each end) or
for continuous (multiple span) beams with equal spans carrying
uniform loads.
A 4" minimum length length and full beam width bearing
is required at end supports, while a 6" minimum length and
full beam width bearing is required at interior supports where
there is a continuous beam (multiple span).
A Qualified Design Professional shall determine the size of
all columns to support the selected beam. All Better Header Steel
W-Shape Steel Beams require steel lally columns.
Live load deflection limits are L/360 and L/240.
Total load deflection limit is L/180.
7.
There is no live load reduction considered in
developing these tables. 8. These tables are designed for
professionals
with structural analysis experience
for
loads during typical housing construction.
They do not account for unusual such
as
ceramic tile floors and heavy point
loads.
9. The tables shown are to be used as
general guidelines for beam selection
and
should be used under the supervision
of a
qualified design professional. Better
Header® can not be held responsible
for
any circumstances. Please contact us
should you need verification or have
questions about table usage.
10. All beam tables are based on laterally
braced conditions and it should
be the
the responsibility of a qualified
design
professional to assure that such
lateral
bracing is provided on your project.
