A Subsidiary of the International Code Council DIVISION: METALS Section: Steel Decking REPORT HOLDER: EPIC METALS CORPORATION TALBOT AVENUE RANKIN, PENNSYLVANIA 504 (42) EVALUATION SUBJECT: EPICORE, ER2R, ER2RA, ER3.5, AND ER3.5A STEEL DECK PANELS.0 EVALUATION SCOPE Compliance with the following code: 202, 2009, and 2006 International Building Code (IBC) Property evaluated: Structural 2.0 USES The EPIC Metals steel deck panels are used in floor and roof decks, horizontal diaphragms, and composite floor and roof assemblies to support the code-required appropriate floor and roof loads. 3.0 DESCRIPTION Epicore, ER2R, ER2RA, ER3.5, and ER3.5A steel deck panels are cold-formed from steel conforming to ASTM A653 SS Grade 40, with a minimum G60 galvanization coating designation. The panels are made from No. 4, 6, 8, 9, 20 or 22 gage steel [base-metal thicknesses of , , , 0.048, or inch (.88,.52,.20,.06, 0.9 or 0.75 mm), respectively]. The panel profiles are as indicated in Figures and 2 of this report. Panel descriptions are as follows:. Epicore: 2-inch-deep (5 mm) floor deck panel with embossments in the top flange for use in composite floor applications. 2. ER2R: 2-inch-deep (5 mm) nonacoustic roof deck panel. 3. ER2RA: 2-inch-deep (5 mm) acoustic roof deck panel with perforations in the bottom flanges for acoustical purposes. 4. ER3.5: 3.5-inch-deep (89 mm) nonacoustic roof deck panel. 5. ER3.5A: 3.5-inch-deep (89 mm) acoustic roof deck panel with perforations in the bottom flanges for acoustical purposes. 4.0 DESIGN AND INSTALLATION 4. General: The section properties and allowable load tables for the panels in this report have been established using the design base-metal thicknesses of the panels noted in Table. Allowable gravity and wind uplift loads must be based on section properties shown in Table. Allowable reactions based on web crippling must not exceed values shown in Table 7. The minimum concentrated live loads of IBC Section 607 must be considered by the design professional based on the specific occupancy or use, as applicable. 4.2 Composite Decks with Vertical Load: Epicore deck panels maximum unshored spans and allowable superimposed uniform live loads for composite decks with various thicknesses of concrete are set forth in Tables 2, 3, 4, and 5, respectively. The concrete fill must comply with the applicable code, utilize normal weight and have a minimum compressive strength of 3000 psi (20.68 MPa). The decking must be clean and free of foreign materials prior to placement of concrete. 4.3 Bare (Non-Composite) Decks with Vertical Load: The ER2R, ER2RA, ER3.5, and ER3.5A panels allowable uniform loads (dead plus live) are shown in Table Diaphragm Design: 4.4. General: The one-third stress increase permitted for Allowable Stress Design, for load combinations in IBC Section including wind or seismic forces, must not be used for shear values in the diaphragm tables. The horizontal diaphragm ASD shear and flexibility factors for the ER2R ER2RA, ER3.5, and ER3.5A decks are shown in Tables 8a, 8b, 8c, and 8d. Typical steel deck diaphragm layouts are shown in Figures 7. End weld patterns for the various decks are shown in Figures 3 and 4. All welding must be accomplished with a minimum / 8 -inch-diameter (3.2 mm) E60XX or E70XX filler metal rod complying with the appropriate AWS standard. Other weld requirements must conform to AWS D.3. Arc seam welds or fillet welds of deck side laps must comply with requirements shown in Figures 5a and 5b.

Arc seam or spot (puddle welds to members such as chords and to collector elements such as struts or ties must have a spacing in feet equal to 32,000 (t) / v: where: t = Uncoated base-metal thickness of fluted deck, in inches. v = Actual diaphragm shear at marginal supports parallel to flutes or actual shear to be transferred to collector elements (at struts or ties), in pounds per foot b. The spacing of welds parallel to flutes must not exceed the deck span divided by three. 8 Attachments at interior lines of shear transfer perpendicular to deck corrugation: The shear transfer from a diaphragm to interior tie or strut lines perpendicular to deck corrugations must not exceed the shear values indicated in the tables. Two lines of puddle welds may be used to develop the actual shear transfer of these collector elements. 9 Where individual panels are cut, the partial panel must be fastened to ensure complete transfer of design shear forces at the point of the diaphragm to adjacent full panels to attain the values specified in the tables.

Refer to Table 8 for determination of the value F. 2 Diaphragms supporting masonry or concrete walls are to have their deflections limited to the following amount: wall = (H 2 / 0.0E t ) f c where: E = Modulus of elasticity of wall material for deflection determination, in pounds per square inch. f c = Allowable compressive strength of wall material in flexure, in pounds per square inch. For concrete, fc = 0.45 f'c For masonry, fc = Fb = 0.33 f'm H = Unsupported height of wall, in feet. t = Thickness of wall, in inches. 3 The total deflection,, of the diaphragm may be computed from the equation: = f + w where: f = Flexural deflection of the diaphragm determined in the same manner as the deflection of beams. w = Web deflection determined by the equation: w = (q avg L F) / 0 6 where: F = Flexibility factor (the average micro-inches a diaphragm web will deflect in a span of foot under a shear of pound per foot). L = Distance between vertical resisting element (such as shear wall) and the point to which the deflection is to be determined, in feet. q avg = Average shear in diaphragm., in pounds per square foot, over length L. 4 When applying these limitations to cantilevered diaphragms, the allowable span-depth ratio will be half that shown. 5 Diaphragm classification (flexible or rigid) and deflection limits must comply with Section of the report.
