Performance Requirements4.1 DesignThe roof system shall be designed for specifieddesign loads and thermal effects.4.1.1 Minimum design loads shall be determined by thegoverning code or the design professional.4.1.2 The finished roof system shall be capable of sustaininga minimum 200-lb (0.
21、9-kN) concentrated load on any 12-in. by12-in. (300-mm by 300-mm) area of finished roof withoutcausing seam separation, permanent panel buckling, or loss ofweathertightness.4.1.3 Thermal movement shall be provided for in accor-dance with Sections 7 and 8. Temperature differentials formany localities
22、 are found in documents referenced in 2.5, 2.6,and Footnote 13.84.1.4 The standing seam roof system clips do not alwaysprovide full lateral support to secondary structural members.The degree of lateral support provided to the secondarystructural members by the panel system shall be determined byan a

25、 broad, flat areas. It is the result of several factors thatinclude, but are not limited to, induced stresses in the basematerial, fabrication methods, and installation and thermalforces. While oil canning is an aesthetic issue, structuralintegrity is not normally affected. Oil canning is not ground

Structural Integrity5.1 Panel System Design:5.1.1 Structural panels shall be designed in accordance withAISI Specification for the Design of Cold-Formed SteelStructural Membersand in accordance with sound en
27、gineer-ing methods and practices.5.1.2 Deflection and serviceability shall be accounted for.9The deflection shall be limited so as to allow the roof toperform as designed. The substrate deflection shall not causestrains to the panels that affect the serviceability of the system.5.2 Panel System Test

35、ase metal thickness shall be as requiredto resist specified design loads.7. Panel Clips7.1 Connections of panels to structural members shall bemade with concealed panel clips compatible with the paneldesign.7.2 Provisions for the thermal movement between the paneland the structure to which it is att
36、ached shall be accomplishedby the use of concealed panel clips allowing such movement,except as provided in 7.3.7.3 When the building geometry and the rotational flexibil-ity of the supporting member permit, it is permissible toresolve thermal movement through controlled rotation of theintermediate
37、structural members rather than movement withinthe clip.7.4 Where insulation is applied between the panels andsupporting structure, the panel clips shall be designed to becompatible with the thickness and compressibility of theinsulation. If thermal spacers are required for thermal perfor-mance, the
38、clips must be compatible with the thermal spacer toreduce secondary stresses due to walking.8. Panel and Clip Anchorage8.1 Afixing line is required to anchor roof panels in order tomaintain end alignment and to resist in-plane gravity andthermal force components.8.2 Fasteners that penetrate the roof
39、 surface are permittedonly at panel endlaps, penetrations, fixing lines, rib reinforce-ments, and at roof termination lines. Details at these locationsshall allow for the expected thermal movement.8.3 Nails shall not be used where subject to withdrawalloads.9. Weather Tightness9.1 Panel-to-panel sid
40、elap connections and endlaps shall beweathertight.9.2 Panels of maximum practical lengths shall be used tominimize endlaps.9.3 Sealers:9.3.1 Sidelap SealerWhen climate, roof slope, and roofsystem design warrant, the standing seam sidelap shall have asealer. When the sealer is factory applied, it sha
41、ll remain inplace and be protected during transit. In some cases, the panelgeometry will provide the required protection. All sealers shallremain in place during panel installation and be protectedduring storage and installation from any contamination orabrasion that unduly affects service.NOTE 3Whe
42、n the slope of the roof is steep, or when the roof systemis in a geographic area with little rainfall or snowfall, a sidelap or endlapsealer may not necessarily be required.9.3.1.1 The sealer shall be of sufficient size and shape to fillthe maximum void to be sealed and to assure compression afteren
43、gagement. The minimum compression shall be 30 % byvolume or the adhesion plus webbing characteristics shall be asrequired to maintain watertightness. An appropriate test shallbe used to demonstrate the roof panel systems resistance toponded water. The sealer shall remain flexible between 0 and140F (
44、17.8 and 60C) to allow engagement, and shall showno signs of cracking when tested in accordance with TestMethod C 765 (wrapped 180 over a 1 in. (2.54 cm) diametermandrel after 4 h at 0F (17.8C). The sealer shall not beexposed after assembly.9.3.1.2 The sealer shall be sufficiently resilient to maint
45、ainthe seal after movement of joints due to fluctuation in externalload, or expansion and contraction, or combination thereof.The maximum set when tested in accordance with Specifica-tion D 1667 shall be 5 % if compression alone is required tomaintain the seal. The sealer shall be capable of maintai
46、ningthe above level of watertightness after exposure to the servicetemperature range, 40 to 200F (40 to 93.3C) unless localor project conditions justify that the specifier impose a differentrange. This watertightness shall be independent of the tempera-ture at the time of panel installation.9.3.1.3
47、The sealer shall be non-corrosive and non-stainingto adjacent materials and shall exhibit these characteristicsafter testing in accordance with Test Method D 3310 includingwater and with elevated temperature exposure for 21 days at160F (71C); the rating shall not exceed “2.” The sealer shallbe fungu
48、s resistant and exhibit this property after testing inaccordance with Practice G21; the rating shall not exceed “1.”In meat and poultry processing facilities or other areas requir-ing USDAinspection, the sealer shall be chemically acceptableto USDA, and shall be requested by the specifier. When FDAc
49、ompliance is required, appropriate FDA regulations shall beincluded by the specifier.9.3.1.4 If the seam design utilizes sealant, and the locationof a clip component interrupts the sealant, the design shall notrely on differential movement between the panel seam and theclip component.9.3.1.5 If the sidelap sealer is interrupted by the installationof a sidelap clip, and if required by the panel system design, theseal shall be completed around the clip. The performancecharacteristics of the supplemental sealer shall be equal to theprimary sidelap sea
