2207 A .1.1 Seismic design. Where required, the seismic design of buildings shall be in accordance with the additional provisions of Section 2205 A .2 or 2211 A .1.1.

2207 A .2 Design. The registered design professional shall indicate on the construction documents the steel joist and steel joist girder designations from the specifications listed in Section 2207 A .1; and shall indicate the requirements for joist and joist girder design, layout, end supports, anchorage, bridging design that differs from the SJI specifications listed in Section 2207 A .1, 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.

1.6. Connection forces.

2. Special considerations including:

2.1. Profiles for joist and joist girder configurations that differ from those defined by the SJI specifications listed in Section 2207 A .1.

2.2. Oversized or other nonstandard web openings.

2.3. Extended ends.

3. Live and total load deflection criteria for joists and joist girder configurations that differ from those defined by the SJI specifications listed in Section 2207 A .1.

2207 A .3 Calculations. The steel joist and joist girder manufacturer shall design the steel joists and steel joist girders in accordance with the SJI specifications listed in Section 2207 A .1 to support the load requirements of Section 2207 A .2. The registered design professional shall be permitted to require submission of the steel joist and joist girder calculations as prepared by a registered design professional responsible for the product design. Where 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 the design calculations submitted under seal and signature, the following shall be included:

1. Bridging design that differs from the SJI specifications listed in Section 2207 A .1, such as cantilevered conditions and net uplift.

2. Connection design for:

2.1. Connections that differ from the SJI specifications listed in Section 2207 A .1, such as flushframed or framed connections.

2.2. Field splices.

2.3. Joist headers.

STEEL

2207 A .4 Steel joist drawings. Steel joist placement plans shall be provided to show the steel joist products as specified on the approved construction documents and are to be utilized for field installation in accordance with specific project requirements as stated in Section 2207 A .2. Steel joist placement plans shall include, at a minimum, the following:

1. Listing of applicable loads as stated in Section 2207 A .2 and used in the design of the steel joists and joist girders as specified in the approved construction documents.

2. Profiles for joist and joist girder configurations that differ from those defined by the SJI specifications listed in Section 2207.1.

3. Connection requirements for:

3.1. Joist supports. 3.2. Joist girder supports. 3.3. Field splices. 3.4. Bridging attachments.

4. Live and total load deflection criteria for joists and joist girder configurations that differ from those defined by the SJI specifications listed in Section 2207 A .1.

5. Size, location and connections for bridging.

6. Joist headers.

2207A.4.1 Design approval. [DSA-SS] Joist and joist girder design calculations and profiles with member sizes and connection details, and joist placement plans shall be provided to the enforcement agency and approved prior to joist fabrication, in accordance with the California Admin- istrative Code (Title 24, Part 1). Joist and joist girder design calculations and profiles with member sizes and con- nection details shall bear the signature and stamp or seal of the registered engineer or licensed architect responsible for the joist design. Alterations to the approved joist and joist girder design calculations and profiles with member sizes and connection details, or to fabricated joists are subject to the approval of the enforcement agency.

2207 A .5 Certification. At completion of manufacture, the steel joist manufacturer shall submit a certificate of compliance to the owner or the owner’s authorized agent for submittal to the building official as specified in Section 1704 A .5 stating that work was performed in accordance with approved construction documents and with SJI specifications listed in Section 2207 A .1.

The chords of all joists shall be laterally supported at all points where the chords change direction.
