Purpose: This IR clarifies the structural design requirements for bleachers. Do not use this IR

for any other structures.

Scope: This IR is applicable only to bleachers, folding and telescopic seating, and grandstands

submitted to DSA for review under the 2016 CBC.

1. Definitions: In addition to those in ICC/ANSI 300, Section 202, the following terms are

defined for this IR.

1.1 School Buildings: DSA reviews and approves the construction of school buildings.

Section 4-314, Part 1, Title 24, California Code of Regulation defines grandstands and

bleachers more than five rows of seats above grade as school buildings.

1.2 Bleacher/Grandstand: ICC 300 defines bleachers and grandstands identically. The

terms “bleacher” and “grandstand” will be used interchangeably in this IR. All provisions

pertaining to bleachers will also be applicable to grandstands and vice versa.

1.3 Portable Bleachers: Seating facilities located outside of a building and not attached to

permanent foundations. The maximum height of any portable bleachers may not exceed

eleven rows, or nine feet above grade to the top seating board.

1.4 Temporary Portable Bleachers: Portable bleachers that remain at a location for less

than 90 days. They are exempted from DSA review, but must be in compliance with the

requirements of ICC/ANSI 300.

1.5 Folding and Telescopic Seating: Indoor tiered seating whose overall size and shape

may be reduced without being dismantled for purposes of moving or storing. Unless

otherwise noted, all provisions in this IR pertaining to bleachers and grandstands will

also be applicable to this type of seating.

1.6 Acceptance of Folding and Telescopic Seating Fabrication Plants: Plants

fabricating folding and telescopic seating for projects under DSA jurisdiction will require

DSA acceptance. To qualify for DSA acceptance, the fabricator shall comply with the

following:

• Obtain and maintain accreditation from any of the following organizations:

loading shall be replaced with the following:

1.2D + 1.6L + 1.6R

(Equation 3-2)

D + L + R

(Equation 3-4)

The L used in Equation 3-2 and 3-4 is the uniform live load defined in ICC/ANSI

300, Section 303.2. Where the element supporting the handrail or guard does not

support this uniform live load, L may be taken as zero.

Note: Contrary to past IR interpretations, the sway loads (Z) and guard or handrail loads

) stipulated in ICC/ANSI 300 shall not be considered live loads (L) in the CBC Load

Combinations in Section 1605A.

3.5 Seatboards and Footboards as Structural Elements: On the basis of full-scale tests,

product tests, previously approved designs, and engineering data that were submitted,

DSA has determined that seatboards and footboards are acceptable alternate structural

• Lateral bracing of the top flange of stringers.

Note: Stringers that are continuous over supports and/or act in

compression shall be designed assuming the bottom flange is laterally

unbraced except at supports and locations specifically designed and

detailed to provide bottom flange lateral bracing.

• Torsional restraint of the stringers. As a result of this torsional restraint, the

stringers need not be designed for torsion induced by sway, seismic and wind

forces. However, where stringers are continuous over supports, the stringer

connection to each support (girder, column, etc.) shall be designed and

detailed to resist torsion (rollover). In addition, stringers directly supporting

guardrails or handrails shall be designed and detailed to resist torsion induced

from guardrail or handrail loads in combination with applicable dead and live

loads.

• Diaphragm action for distribution of sway, seismic and wind forces.

3.6 Footings: Footings for all bleachers are required to comply with CBC, Section 1808A,

except temporary portable bleachers as defined in Section 1.2 above may be supported
