AISC certified manufacturing
New Millennium manufactures FreeSpan"! castellated and cellular beams right
here in the USA at our production facility in Continental, Ohio.
During the castellated beam production process, a solid steel beam forged from
recycled steel is cut in half lengthways, using automated plasma torch cutting.
The split halves are then offset and welded back together to create a beam that
is the same weight, but is now deeper, stronger, and ideally suited for long span
applications.
Our highly efficient manufacturing facilities can produce 90-foot castellated beam
sections. Customized beams are engineered to address unique project needs,
including welded infill sections for special connection points.

How to Specify
Deflection and Camber
FreeSpan"! castellated and cellular beam deflection is
calculated using simple beam theory, with Ieffective = 0.9 Ix_net.
If camber is required, it is the responsibility of the designer
to indicate the camber requirements on the contract framing
plan. FreeSpan"! beams have the advantage of inexpensive
cambering during the manufacturing process.
Floor Vibration
Floor vibration characteristics may be checked following
the same procedure used for wide-flange beams, as
discussed in the American Institute of Steel Construction
Design Guide 11, Floor Vibrations Due to Human Activity.
Due to their high stiffness-to-weight ratio, FreeSpan"!
castellated and cellular beams are often preferred for
use in vibration sensitive applications.

with minimum 1.0 mils dry film thickness.
FreeSpan"! beams can be furnished with a galvanized
finish. When using a galvanized finish, it is important to
minimize stress risers such as abrupt changes in cross
section. For this reason, we recommend the use of
cellular beams rather than castellated for use with
galvanized finishes.
Welding
All welding procedures and welders are certified in
accordance with AWSD1.1.

Design
FreeSpan"! castellated and cellular beams are designed
in accordance with the American Institute of Steel
Construction (AISC) Specification for Structural Steel
Buildings, 14th Edition, ANSI/AISC 360-10.
FreeSpan"! castellated and cellular beams are designed
similar to Vierendeel trusses. The design approach is based
on the procedure outlined in Book of Welded Structures, by
Omar Blodgett, and includes the following checks:
Overall Bending
Appropriate checks are made for the overall beam stability
and flexural strength, as a function of lateral bracing and
effective unbraced length.
Shear
Three potential shear limit states are checked
for FreeSpan"! beams:
1. Vertical shear thru the gross section at a web post
2. Vertical shear through top and bottom T-sections at
a web opening
3. Horizontal shear at the web post and weld
T-Section Flexural Stresses
Similar to a Vierendeel truss, the transfer of vertical shear
across the web openings results in local bending stresses
within the top and bottom T-sections. This local bending
stress must be considered in combination with the tension
and compression resulting from the overall beam flexural
stresses, as well as the shear stresses.
Web Post Buckling
The FreeSpan"! web posts are subjected to a variety of
stresses. Just as with the T-Sections at web openings, the
web posts are subjected to flexural stresses resulting from
shear transfer, in addition to vertical and horizontal shear,
as well as compression due to loads applied to the top
flange. Web post buckling strength is checked based
on research performed by Dr. Richard Redwood of
McGill University.

Bridging requirements for common FreeSpan"! beam sizes

requirements shown are based on a maximum construction
load of a 4000 lb deck bundle equally supported across
a minimum of three FreeSpan"! beams, plus two employees.

End-to-End Structural Steel Solutions
Assure the winning success of your project, with our full range
of structural steel roofing and flooring systems:
BIM Design Collaboration
We participate in BIM-based projects using our industry-leading
Dynamic Joist® digital design component. The component is
available as a free, downloadable add-on for Tekla Structures.
Additional components are in development at New Millennium
to support our many product lines and for use with other digital
software provider formats.
Standard Steel Joists
Joist products include K, LH and DLH Series joists and joist
girders, and CJ Series joists (Composite Joist). Joists can be
furnished as a single-piece up to 15 feet deep and 125 feet
long. All are produced in accordance with the specifications
of the Steel Joist Institute.
Flex-Joist"! Gravity Overload Safety System
New Millennium s Flex-Joist"! is uniquely designed to flex prior
to collapse under extreme gravity overload conditions. The slow
stretching of steel in tension leads to large inelastic deflections
and results in a slower collapse, adding crucial time for
emergency response. We achieve this ductile behavior by
limiting component relative strength ratios such that a primary
tension member is the weakest steel joist component. The
Flex-Joist"! design improves steel joist reliability and increases
the probability of safe evacuations while generally decreasing
the probability of a collapse.
Special Profile Steel Joists
Unique roofline designs are now practical and economical
using special profile steel joists, due to our development of
engineering specifications enabling over 40,000 special profile
steel joist design possibilities. We manufacture a complete
range of special profile steel joist products, including bowstring,
arched, scissor, double-pitched, and single-pitched joists.
Steel Roof and Floor Decking
Metal deck options include roof deck, form deck and composite
deck. Engineered to the application, our steel decking systems
are certified to address performance requirements related to
such factors as wind uplift, fire resistance and noise reduction.
