2.2PERFORMANCE REQUIREMENTS

  1. General: Installed glazing systems shall withstand normal thermal movement and wind and impact loads (where applicable) without failure, including loss or glass breakage attributable to the following: defective manufacture, fabrication, or installation; failure of sealants or gaskets to remain watertight and airtight; deterioration of glazing materials; or other defects in construction.

Retain "Delegated Design" Paragraph below if Contractor is required to assume responsibility for design.

  1. Delegated Design: Engage a qualified professional engineer, as defined in Section014000 "Quality Requirements," to design glazing.
  2. Structural Performance: Glazing shall withstand the following design loads within limits and under conditions indicated determined according to the IBC and ASTME1300.

Retain one of two "Design Wind Pressures" subparagraphs below, usually first. The IBC requires that design wind pressures used for design of exterior components and cladding not designed by the registered design professional be shown on the Construction Documents.

  1. Design Wind Pressures: As indicated on Drawings.
  2. Design Wind Pressures: Determine design wind pressures applicable to Project according to ASCE/SEI7, based on heights above grade indicated on Drawings.
  3. Wind Design Data: As indicated on Drawings.

Retain "Wind Design Data" Subparagraph above or "Basic Wind Speed," "Importance Factor," and "Exposure Category" subparagraphs below; insert other design data if required. The IBC requires that data in subparagraphs below be shown on the Construction Documents.

  1. Basic Wind Speed: [85 mph (38m/s)] [90 mph (40m/s)] [100 mph (44m/s)] [110 mph (49m/s)] <Insert value>.
  2. Importance Factor: [1.0] <Insert factor>.
  3. Exposure Category: [B] [C] [D].

Retain "Design Snow Loads" Subparagraph below if sloped glazing is exposed to snow loads. The IBC requires that the flat-roof snow load be shown on the Construction Documents if the ground snow load exceeds 10 lbf/sq. ft. (0.479 kN/sq.m).

  1. Design Snow Loads: <Insert design snow load> [As indicated on Drawings].
  2. Thickness of Patterned Glass: Base design of patterned glass on thickness at thinnest part of the glass.

"Probability of Breakage for Sloped Glazing" Subparagraph below is an example only and is more conservative than ASTME1300 and the IBC, which are based on a probability of breakage of 0.008.

  1. Probability of Breakage for Sloped Glazing: For glass surfaces sloped more than 15 degrees from vertical, design glass for a probability of breakage not greater than 0.001.

Deflection requirements in "Maximum Lateral Deflection" Subparagraph below are examples only and apply only to glass supported on all four edges. The IBC does not contain any deflection limits for glass. ASTME1300 only requires that the deflection not result in loss of edge support. Revise to suit Project.

  1. Maximum Lateral Deflection: For glass supported on all four edges, limit center-of-glass deflection at design wind pressure to not more than 1/50 times the short-side length or 1 inch (25 mm), whichever is less.

"Differential Shading" Subparagraph below applies primarily to tinted glass because of its heat-absorbing property. ASTME1300 and the IBC do not address this concern.
