Appeal Information Sheet
Appeal item 1
| Code Section | 1608.2.3, 1608.2.4, 1608.2.5 |
|---|---|
| Requires | 1608.2.3 specifies that the snow load shall be a minimum of sloped snow load and rain-on-snow load from sections 1608.2.4 and 1608.2.5 |
| Code Modification or Alternate Requested | To not design for Snow Load after a 2 hour burned condition, only prior to a potential burn. |
| Proposed Design | The roof canopy Glu laminated structure is designed for the code required snow loads, including snow drift in the unburned condition. The center beam line is not required to have a char rating nor are the two interior center columns but we have matched the glulam sizes used at the exterior walls so these members are all oversized by 6.4" in each direction compared with code minimum. |
| Reason for alternative | We did not include snow loads on the burned analysis, since the polycarbonate roofing, the 2x purlins, and the 4x rafters would be reduced to zero since a reduction of 3.2” (Section 16 of the NDS requires that the beams be reduced by 3.2” on all exposed sides) on (3) sides exposed would eliminate them. Therefore, the roof snow and roof snow drift would no longer have a roof deck/structure in place to support it after a 2-hr fire. Using engineering judgment, it seems obvious that if no roof deck is present to support roof snow accumulation, the remaining burned/charred roof glulam beams and columns will not have snow to support. By upsizing the sizes of the interior columns and beam we have provided for greater life safety than that which code requires in both a burned and unburned state. Additionally the patio is fully sprinklered as is the adjacent building therefore even a 1 hour burned condition is extremely unlikely to ever exist. |
Appeal Decision
Omission of snow load from calculation of exposed beam in post-fire condition: Granted as proposed.
"The Administrative Appeal Board finds that the information submitted by the appellant demonstrates that the approved modifications or alternate methods are consistent with the intent of the code; do not lessen the health, safety, accessibility, life, fire safety or structural requirements; and that special conditions unique to this project make strict application of those code sections impractical.
