Multi-Hazard Mitigation Plan: 17. Shelters

Home

Chapter-17:Shelters • Complete all retrofits listed above required for Type A and Type B classification • Install a deployable protective screen enclosure or similar device around the building to allow a safe access corridor to the restrooms. The screen must be pressure rated for design windspeeds of 140 mph or greater and missile level D impact rated or higher • Since most structural elements begin to approach or exceed their allowable load capacity under partially enclosed conditions at around the minimum acceptable windspeeds for Type EHPA shelters, the wind loads can be reduced by creating enclosed conditions. To accomplish this all fixed louvers must be closed by some method during storm events or operable louvers installed. These and all other openings must be pressure rated for design windspeeds of 140 mph or greater and missile level D impact rated or higher. • Provide retrofits so that all openings (doors, windows, and louvers) meet ASTM E 1886 and ASTM E 1996 test standards for 140 mph design wind pressures and missile impact level D protection or better, or provide documentation of any existing openings that may be claimed to meet these performance requirements. 17.1.1.4 Konawaena Elementary School- Cafetorium Building C Ads— x SaffirSimpson Storm Categories and Shelter Classes E st ng Wincow Fetroftled Windows Existing M'NFRS jjjjjf � �III III n Cable Open ng S Donner Ope-ing= {Partially Eridused'i m ,m, CAegoryI Categary2 Categay3 .6 Categoryd m n ExistngG Metal Roof at Sneher reaS Based an PDject C-cedic 1 ta' a2 92 102 112 122 132 "142 152 1$2 172 132 192 3-Seeon d Peak Gust Windspeed Strength Capacity Building C would classify as a Type B hurricane shelter in its existing condition.
