Scope This standard covers the procedure for deter- mining the Moment of Resistance (Mr) and Minimum Characteristic Resistance Load (F) to install a tile system on buildings of a specified roof slope and height. Compliance with the re- 3. quiroments and procedures herein specified, where the pressures (Pj have been deternrinad based on Table I or Table, 2 of this standard, as applicable, do not require additional signed and sealed engineering design calculation. All other calculations must be prepared, signed and sealed by a professional engineer or registered architect. Table I is applicable to a wind speed of 175 mph, risk category II buildings, and ex- posure category C. Table 2 is applicable to a wind speed of 175 mph, risk category It build- ings, and exposure category D. How to determine the Moment Resistance (M,) (Moment Based Systems) 2.1 Determine the. minimum design wind pressures for the field, perimeter and cor- ner areas (P,,I, P.42 and P,3, re-spec- tively) using the values given in Table I or Table 2, as applicable, or those. obtained by engineering analysis prepared, signed and sealed by a professional engineer or iegistmed architect based on ASCE 7. 2.2 Locate the aerodynamic 2.3 Determine the restoring moment due to gravity (M,) per Product Approval. 2.4 Determine the attachment resistance per Product Approval. 2.5 Determine tile, Moment of Resistance (K) per following formula: M, = (P� x X) - ME 2,6 Compare the values for M,, with the val- ues forM, noted in thaProduct Approval. If the Mfvalues are greater than ofequal to the M, values, for each aria of the roof' [i.e., fleld P.(I), perhileter P,,(2) and corner P.J3) areas], then ifie tile attach - How to determine the Minimurn'CharReter- istic Resistance Load (F) (Uplift Based Sys- tem) 3.1 Determine the minimum design pressures for die field, perimeter and corner areas [P..,JI), P.(2) and P.,(3), respectively] using the values given in Table I or'llable 2, as applicable, or those obtained by en- gineering analysis prepared, signed end sealed by a professional engineer or regis- tered architect based on the criteria set forth in ASCE 7. 3.2 Determine the angle (0) of roof slope, from Table 1 or Table 2, as applicable. 3J Determine the length (1), width (w) and average tile weight M of tile, per Prod- uct Approval. 3.4 Determine the required uplift resistance (F,) per following formula: F, = [(P� x I x W) - W3 x Cos 0 3.5 Compare the values for F, with the values for F noted in the Product Approval. If the F values ue greater than or equal to the F, values, for each area of roof [i.e., field P,,(I) perimeter (P.,(2) and comer P,,d(3) areas], then the tile attachment method is acceptable. 2010 FLORIDA BUILDIMG CODE —T5ST PROTOCOLS HVHZ (RAS) 127A (RAS) No. 127 TABLE I - RISK CATEGORY if EXPOSURE CATEGORY "C"' MINIMUM DESIGN WIND UPLIFT PRESSURES IN PSF FOR FIELD [P,,(1)1, PERIMETER [P.d(2)1 AND CORNER [P..d(3)) AREAS OF ROOFS FOR EXPOSURE 0 BUILDINGS WITH A ROOF MEAN HEIGHT AS SPECIFIEDO ROOF SLOPE >2:12 to 56;12 > 6:12 to 512:12 P.�(2) & Roof mean height P�P) pw(2) ]?�(3)2 P�ji) P.,(3) 5 20' -39.1 -68.1 -100.7 42.8 -50.0 >20'to --� 25' -40.9 -71.3 -105. - >25'to !C 30' -42.4 -73.9 -109.3 -46.4 -54.3 >3U to:5 35' -43.9 -76.6 -113.2 -48.1 -56.2 >35'to:T. 40' -45.1 -78.7 -116.3 49A -57.8 I Calculated in accordance with ASCS. 2 For Hip Roofs with slope!� 5.5:12, Pad(3) shall be treated as P�,,(2). 3.P.d = 0-61F.0 TABLE 2 - RISK CATEGORY If EXPOSURE CATEGORY "D"' MINIMUM DESIGN WIND UPLIPI'PRESSURES IN PSF FOR FIELD [P.d(t)], PERIMETER [P.�d(2)1 AND CORNER [P�d[3)j AREAS OF ROOFS FOR EXPOSURE D BUILDINGS WITH A ROOF MEAN HEIGHT AS SPECIFIEVe ROOF SLOPE > 2:12 to 5 6:12 > 6;12 to!M:12 PJ2) & Roof mean height pa'(1) P.P) P�(3)2 ps,'(1) P,,(3) 5 20' 47.0 -81.9 -121.0 -51.4 -60.1 >20'to !9 25' -48.8 -85,0 -125.7 -53.4 -62.4 >25' to -5 30' -50.3 -87.7 -129,.6 -55.0 -64.4 >39 to --9 351 -51.5 -B9.9 -132.7 -56.4 -65.9 >35'to!�40' -52.7 -91.9 -67.9 ' Calculated in accordanco with ASCE 7. 2 For Hip Roofs with slope --S 5.5:12, P1,P) shall be treated as Plld(Z)' ' Pqm � 0.6Fu, (RAS) 127.2 2010 FLORIDA BUILDING CODE - TEST PROTOCOLS HVHZ (RAS) No. 127 TABLIE3 WH5RE TO OBTAIN INFORMATION Deacrlpilon Symbol Where to find Design Pressure P,(l) or P.,(2) or P�,(3) :Table I orTable 2, as applicable, or by an engineer analysis prepared, signed and. scaled by a professional engineer based on ASCE 7 Mean Roof Height H Job Site Roof Slope Job Site Acrodynamaic Multiplier Product Approval Restoring Moment due to Oravity, M, Product Approval Attachment Resistance Product Approval Required Moment Resistance M, Calculated Minimum Characteristic Resistance Load F oval Required Uplift Resistance P, Calculated Average Tile Weight I w Product Approval Tile Dimensions Mength w=width Product Approval All CRICUIALIDuS must be submitted to the building official at the time of permitting. 2010 FLORIDA BUILDING CODE — TEST PROTOCOLS HVHZ (AAS) 127.3 3 LibuTATIONs: 3.1 Fire classification is not pad of this acceptarim 3.2 For mortar or adhesive set tile allPlications� a static field uplift test in accordance with TAS 106 shall be required, refer to applicable Building Code. 3.3 Applicant shall retain the services of a Wtami-Dade County Certified Laboratory to perform quarterly test in accordance with TAS 112, appendixA'- Such testing shall be submitted to the Nfiami-Dade County Product Control Section for review. 3.4 Minimum underlayment shall be in compliance with the applicable Roofing Applications Standards listed section 4- t herein, 3.5 '30/90 hot mopped underlayment applications may he installed perpendicular to the roof slope unless stated otherwise by the underlayment material manufacturers published literature. 3.6 This acceptance is for wood deck applications- Minimum deck requirements shall be in.compliance with applicable Building Code. 4 NSTALLATION: 4.1 Eagle Roofing Products LLC Bd Air, Be] Air Double Eagle, Ponderosa, Golden Eagle; Ponderosa Double Eagle Flat Concrete Roof Tiles and its components shall be installed in strict compliance with Roofing Application Standard RAS I 18, RAS 119 and RAS 120. 4.2 Data For Attachment Calculations Table 1: Average Weight (W) and Dimensions Q x w) Tile Profile Weight-W Obf) Length-11 (ft) Wldth�w (ft) Bel Air, Bel Air Double Eagle, 1 �14 1.42 1.03 Ponderosa, Golden Eagle, Ponderosa Double Eagle Flat Tile Table erodynami pliem - 1 Tile Pronle 7" A (ft3) fe A (ft3) A (f tI Batten Application rect Deck Application Bel Air, Bel Air Double Eagle, . 01 ,0.301 2 , 0.278 Ponderosa, Golden Eagle, Gold.
