24、pport provided to the secondarystructural members by the panel system shall be determined byan appropriate test, or in the absence of such test, the panelmust be assumed to provide no lateral support.NOTE 2The Base Test Method for Purlins Supporting a StandingSeam Roof System in the AISI S100 Cold-F

26、canning is an inherent characteristicof products covered by this specification, particularly thosewith 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
27、canning is an aesthetic issue, structuralintegrity is not normally affected. Oil canning is not groundsfor panel rejection unless it does not meet prior standardsestablished by the specifier.5.

28、e Specifications for Aluminum Structures and in accordancewith sound engineering methods and practices.5.1.2 Deflection and serviceability shall be accounted for.10The deflection shall be limited so as to allow the roof toperform as designed.

A., “Serviceability Design Considerations forLow-Rise Buildings,” AISC Design Guide, No. 3.E1637 98 (2017)126.2 Aluminum alloy, temper, and metal thickness shall be asrequired to resist specified design loads.7. Panel Clips7.1 Connections of panels to structural members shall
35、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 attached shall be accomplishedby the use of concealed panel clips allowing such movement,except as provided in 7.3.7.3 When the building geometr
36、y and the rotational flexibil-ity of the support members permit, it is permissible to resolvethermal movement through controlled rotation of the interme-diate structural members rather than movement within thepanel clip.7.4 Where insulation is applied between the panels andsupporting structure, the
37、panel clips shall be designed to becompatible with the thickness and compressibility of theinsulation. If thermal spacers are required for insulationperformance, the panel clip must be compatible with thethermal spacer to reduce secondary stresses due to walking.8. Panel and Clip Anchorage8.1 Afixin
38、g 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 surface are permittedonly at panel endlaps, penetrations, fixing lines, ribreinforcements, and at roof termination lines. Detail
39、s at theselocations shall allow for the expected thermal movement.8.3 Nails shall not be used where subject to withdrawalloads.9. Weather Tightness9.1 Panel-to-panel sidelap connections and endlaps shall beweathertight.9.2 Panels of maximum practicable lengths shall be used tominimize endlaps.9.3 Se
40、alers:9.3.1 Sidelap SealerWhen the climate, roof slope, androof system design warrant, the standing seam sidelap shallhave a sealer (see Note 3). When the sealer is factory applied,it shall remain in place and be protected during transit. In somecases, the panel geometry will provide the required pr
41、otection.All sealers shall remain in place during panel installation andbe protected during storage and installation from any contami-nation and abrasion that unduly affects service.NOTE 3When the slope of the roof is steep, or when the roof systemis in a geographic area with little rainfall or snow
42、fall, 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 ensure compression afterengagement. The minimum compression shall be 30 % byvolume, or the adhesion plus webbing characteristics shall
43、beas required to maintain watertightness.An appropriate test willbe used to demonstrate the roof panel systems resistance toponded water. The sealer shall remain flexible between 0 F( 18 C) and 140 F (60 C) to allow engagement and shallshow no signs of cracking when tested in accordance with TestMet

(25-mm) diametermandrel after4hat0F.Thesealer shall not be exposed afterassembly.9.3.1.2 The sealer shall be sufficiently resilient to maintainthe seal after the movement of joints due to fluctuation inexternal load or expansion and contraction, or both. Whentested
45、 in accordance with Specification D1667, the maximumset shall be 5 % if compression alone is required to maintainthe seal. The sealer shall be capable of maintaining the abovelevel of watertightness after exposure to the service tempera-ture range, 40 F ( 40 C) to 200 F (93 C) unless local orproject
46、 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 The sealer shall be noncorrosive and non-staining toadjacent materials and shall exhibit these characteristics aftertesting in accord
47、ance withTest Method D3310, including waterand with elevated temperature exposures for 21 days at 160 F(71 C); the rating shall not exceed 2. The sealer shall befungus resistant and exhibit this property after testing inaccordance with Practice G21; the rating shall not exceed 1. Inmeat and poultry
48、processing facilities or other areas requiringUSDA inspection, the sealer shall be chemically acceptable toUSDA and shall be requested by the specifier. AppropriateFDAregulation(s) shall be included by the specifier when FDAcompliance is required.9.3.1.4 If the seam design utilizes sealant, and the
49、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 sealer. Both sealers aging characteristics shallsustain the above performanc
