Structural
2.0 USES
Akron fixed and adjustable columns are steel prefabricated
columns for use as structural members to transfer axial
compressive loads from steel or wood beams to concrete
foundation.
3.0 DESCRIPTION
3.1 Adjustable Columns:
Table 1 lists the dimensions of the various adjustable
columns manufactured by The Akron Products Company.
All are available in ASTM A 500 Grade B (42 ksi yield
strength). The 3
1
/
2
-inch diameter by 0.216 inch thick
column is also available in Grade A (33 ksi yield strength).
All are available in 6 foot to 12 foot lengths.
3.2 Fixed Columns:
Fixed columns are the same as the adjustable columns,
without the adjusting mechanism. They are available with a
minimum 0.120-inch-thick ASTM A 1011 CS Type B steel
plate welded to each end, or with one plate welded to one
end and the other plate attached by straps (to be welded to
the column after sizing in the field; see Section 4.3).
4.0 INSTALLATION
4.1 Design:
The available concentric axial compressive strengths for
adjustable and fixed columns are noted in Tables 2 and 3,
for both allowable strength (ASD) and design strength
(LRFD). The actual axial compressive load applied to the
adjustable or fixed columns must be less than the
allowable strength or design strength loads, as applicable,
specified in this report. The capacity of the end plates must
be calculated in accordance with applicable code
requirements for the steel, concrete or wood to determine
whether the supplied end plate thickness is adequate for
the applied load interface (wood beams, steel beams or
concrete).
4.2 Installation:
Installation of the Akron adjustable and fixed columns
described in this report must comply with this report and
the manufacturer’s published installation instructions. The
manufacturer’s published installation instructions and
engineering drawings must be available at the jobsite at all
times during installation. When the manufacturer’s
published installation instructions differ from this report,
this report governs.
Akron adjustable and fixed columns must be installed
vertically with the bottom supported by a foundation
capable of supporting the imposed loads. Adjustable
columns must be adjusted to the desired length. The
adjustable columns are installed with the adjustment screw
at the base. After installation, the adjustment assembly
must be encased in concrete to prevent movement after
installation. Fixed columns are sized by cutting the un-
plated end of the post. The cut end of the post must be
smooth and level in order to fit flush with the end plate.
4.3 Special Inspection:
Field-welding of end plate to post requires special
inspection in accordance with IBC Section 1704.3 and
Table 1704.3. The weld material used must be E70XX or
E60XX, with the welds conforming with the procedures
given in AWS D1.1 or AWS D1.3. Special inspection in
accordance with Section 1704 of the IBC must be provided
for field-welding under the IRC. The code official must
receive a report, from an approved special inspector, that
includes the following details:
1. The post description, including the product name,
series number, initial length, final length, plate size and
thickness.
