PERFORMANCE CRITERIA Structural Loading: Wind Loading: [Indicate wind required wind load] [As indicated on Drawings] Design loads Positive (inward) design pressure of 45 psf Negative (outward) design pressure of 45 psf Deflection Limits Deflection of any framing member in a direction normal to the plane of the wall when subjected to the indicated design loads shall not exceed l/175 of its clear span or ¾ inch, whichever is less. For cantilevers, the span shall be taken as two times the distance between anchor centerline and end of cantilever. The deflection shall not exceed 50 percent of the nominal joint width at sealant joints occurring between framing members and adjacent materials, unless otherwise required by sealant manufacturer. Upon reversal of load direction at magnitudes up to and including 1.5 times design pressures, slippage at fastened and/or clamped connections, shall not exceed 1/8 inch. Glass deflection at full design load shall not exceed 1/100 of its span, or ¾ inch, whichever is less. Metal panel deflection shall not exceed 1/90 of its span or ¾ inch, whichever is less. The span shall be taken as the lesser of the distances between the horizontal or vertical support members. Thermal Movement Provide for expansion and contraction of component materials as will be caused by surface temperatures ranging from 20 degrees F to a high temperature of 180 degrees F. The expansion and contraction caused by temperature differential shall not cause buckling, undue stress on glass, failure of joint seals, undue stress on structural elements, demanding loads on fasteners, reduction of performance, or other detrimental effects. Note: (Specifier DELETE Ballistic and Blast resistance requirements that are not project specific.) Ballistic Resistant: Level [1] [2] [3] in accordance with UL 752 Testing for Ballistic Resistance for the – complete assembly including framing, glazing and panels. Blast Resistant [GSA Building Classifications [C ] [D ] Blast Resistant in accordance with GSA PBS-P100 Facilities Standards] [Low Level Blast Resistant in accordance with current UFC 4-010-01Unified Facilities Criteria (UFC) DOD Minimum Antiterrorism Standards for Buildings]
