International Building Code 2206.1
General. The design, manufacture and use of open web
steel joists and joist girders shall be in accordance with one of
the following Steel Joist Institute (SJI) specifications:
1. SJI K-1.1
2. SJI LH/DLH-1.1
3. SJI JG-1.1
Where required, the seismic design of buildings shall be in
accordance with the additional provisions of Section 2205.2 or
International Building Code 2206.2
Design. The registered design professional shall indicate
on the construction documents the steel joist and/or steel
joist girder designations from the specifications listed in Section
2206.1 and shall indicate the requirements for joist and
joist girder design, layout, end supports, anchorage, non-SJI
standard bridging, bridging termination connections and bearing
connection design to resist uplift and lateral loads. These
documents shall indicate special requirements as follows:
1. Special loads including:
1.1. Concentrated loads;
1.2. Nonuniform loads;
1.3. Net uplift loads;
1.4. Axial loads;
1.5. End moments; and
1.6. Connection forces.
2. Special considerations including:
2.1. Profiles for nonstandard joist and joist girder
configurations (standard joist and joist girder
configurations are as indicated in the SJI catalog);
2.2. Oversized or other nonstandard web openings;
2.3. Extended ends.
3. Deflection criteria for live and total loads for non-SJI
International Building Code 2206.3
Calculations. The steel joist and joist girder manufacturer
shall design the steel joists and/or steel joist girders in
accordance with the current SJI specifications and load tables
to support the load requirements of Section 2206.2. The registered
design professional may require submission of the steel
joist and joist girder calculations as prepared by a registered
design professional responsible for the product design. If
requested by the registered design professional, the steel joist
manufacturer shall submit design calculations with a cover letter
bearing the seal and signature of the joist manufacturer’s
registered design professional. In addition to standard calculations
under this seal and signature, submittal of the following
shall be included:
1. Non-SJI standard bridging details (e.g. for cantilevered
conditions, net uplift, etc.).
2. Connection details for:
2.1. Non-SJI standard connections (e.g. flush-framed
or framed connections);
2.2. Field splices; and
2.3. Joist headers.
International Building Code 2206.4
Steel joist drawings. Steel joist placement plans shall
be provided to show the steel joist products as specified on the
construction documents and are to be utilized for field installation
in accordance with specific project requirements as stated
in Section 2206.2. Steel placement plans shall include, at a
minimum, the following:
1. Listing of all applicable loads as stated in Section 2206.2
and used in the design of the steel joists and joist girders
as specified in the construction documents.
2. Profiles for nonstandard joist and joist girder configurations
(standard joist and joist girder configurations are as
indicated in the SJI catalog).
3. Connection requirements for:
3.1. Joist supports;
3.2. Joist girder supports;
3.3. Field splices; and
3.4. Bridging attachments.
4. Deflection criteria for live and total loads for non-SJI
5. Size, location and connections for all bridging.
6. Joist headers.
Steel joist placement plans do not require the seal and signature
of the joist manufacturer’s registered design professional.
International Building Code 2206.5
Certification. At completion of fabrication, the steel
joist manufacturer shall submit a certificate of compliance in
accordance with Section 1704.2.2 stating that work was performed
in accordance with approved construction documents
and with SJI standard specifications.
