Steel deck panels comply with a code-referenced material standard and have the minimum thickness and minimum yield strength noted in Table 5. See Figures through 5 for panel configuration requirements..5 Wood Structural Panel Horizontal Diaphragms:.5.1 Wood Structural Panel: Wood structural panels must have a minimum thickness of 15 / 2 inch (11.9 mm) and must comply with the requirements of Section of AF&PA SDPWS (which is referenced in IBC Section 205)..5.2 Structural Steel Supports: Structural steel framing members supporting the wood structural panel diaphragm must comply with the minimum strength requirements of ASTM A6, ASTM A572 Grade 50 or ASTM A992, and have a thickness greater than or equal to / 16 inch (4.8 mm). 4.0 DESIGN AND INSTALLATION 4.1 Design: Allowable Loads: The allowable shear and tension loads for the X-U and X-U 15 fasteners installed in steel, and the X-U fasteners installed in normal-weight concrete, sand-lightweight concrete, sand-lightweight concrete-filled steel deck and masonry, can be found in Tables 2 through 6 as summarized in Table 1. The stress increases and load reductions described in IBC Section are not allowed for wind loads acting alone or when combined with gravity loads. No increase is allowed for vertical loads acting alone. Allowable loads apply to the connection of the fastener to the base material only. Design of the connection to the attached material must comply with the applicable requirements of the IBC. Allowable loads for fasteners subjected to combined shear and tension forces are determined by the following formula: where: (p/p a ) + (v/v a ) 1 p = Actual tension load, lbf (N). P a = Allowable tension load, lbf (N). v = Actual shear load, lbf (N). V a = Allowable shear load, lbf (N) Wood to Steel, Concrete, or Masonry: Reference lateral design values for fasteners determined in accordance with Part 11 of ANSI/AF&PA NDS are applicable to Hilti fasteners of equal or greater diameters. The wood element must be considered to be the side member. The fastener bending yield strength is allowed to be taken as the value noted in the NDS based on the fastener diameter. Hilti carbon steel fasteners may be used in contact with fire-retardant-treated wood in dry, interior locations only, in accordance with IBC Section and Hilti s recommendations. Use of fasteners in contact with preservative-treated wood or fire-retardant-treated wood in exterior applications is outside the scope of this report Wood Structural Panel Horizontal Diaphragms: When the X-U fastener is used to fasten wood structural panels to steel members, the fastener is recognized as equivalent to a 10d common nail. Diaphragm design, including fastener spacing, diaphragm capacity and diaphragm deflection, must comply with Section 4.2 of AF&PA SDPWS (which is referenced in IBC Section 205.1) and IBC Section Seismic Considerations: Use with Structural Components: Resistance to seismic loads is outside the scope of this report. Therefore, except as noted in Section 4.1., the suitability of the Hilti fasteners for use with structural components that are subjected to seismic loads is outside the scope of this report Use with Nonstructural Components: Seismic load resistance is outside the scope of this report, except when used with architectural, mechanical and electrical components described in Section of ASCE 7, and as follows: Concrete base materials: The Hilti fasteners installed in concrete may be used to support acoustical tile or lay-in panel suspended ceiling systems, distributed systems and distribution systems where the service load on any individual fastener does not exceed the lesser of 90 lbf (400 N) or the published allowable load shown in Tables, 4 and 5, as applicable. Steel base materials: The Hilti fasteners installed in steel may be used where the service load on any individual fastener does not exceed the lesser of 250 lbf (1112 N) or the published allowable load shown in Table 2. The Hilti fasteners may also be used in conjunction with wood structural panel diaphragms in accordance with Sections.5, 4.1. and For interior, nonstructural walls that are not subject to sustained tension loads and are not a bracing application, the power-driven fasteners may be used to attach steel track to concrete or steel in all Seismic Design Categories. In Seismic Design Categories D, E, and F, the allowable shear load due to transverse pressure shall be no more than 90 pounds (400 N) when attaching to concrete; or 250 pounds (1,112N) when attaching to steel. Substantiating calculations shall be submitted addressing the fastener-to-base-material capacity and the fastener-to-attached-material capacity. Interior nonstructural walls are limited to locations where bearing walls, shear walls or braced walls are not required by the approved plans. The design load on the fastener must not exceed the allowable load established in this report for the concrete or steel base material. 4.2 Installation: General: The X-U and X-U 15 fasteners must be installed in accordance with this report and the Hilti, Inc., published installation instructions. A copy of these instructions must be available on the jobsite at all times during installation. Installation must be limited to dry, interior locations. Fastener placement requires the use of a low-velocity powder-actuated tool in accordance with Hilti, Inc. recommendations. Installers must be certified by Hilti and have a current, Hilti-issued, operator s license Fastening to Steel: When installed in steel, minimum spacing between fasteners must be 1 inch (25.4 mm) and minimum edge distance must be 1 / 2 inch (12.7 mm).

Minimum spacing between fasteners must be 4 inches (102 mm) and minimum edge distance must be inches (76 mm). Unless noted otherwise in this report, concrete thickness must be a minimum of three times the penetration depth of the fastener DX-KWIK System: Installation of the X-U fastener into normal-weight concrete, using the Hilti DX-KWIK system as an alternate procedure, requires the drilling of a pilot hole using a Special DX-KWIK drill bit (TX-C) supplied by Hilti, Inc., prior to the installation of the fastener with the powder-actuated tool Fastening to Sand-lightweight Concrete-filled Steel Deck Panels: Installation in sand-lightweight concrete-filled steel deck panels must comply with Figures through 5. Minimum distances from fastener centerline to rolled deck panel flute edges must be as depicted in Figures through Fastening to Masonry: Fasteners must be driven into the masonry after the mortar and grout materials have attained the specified strength. Fasteners must be located in accordance with Table Wood Structural Panel Diaphragms: The wood structural panels must be fastened to the steel members at the spacing specified in the design. When used, the optional steel strap is placed on top of the panels and the fasteners are driven through the strap and panel into the supporting steel member. The minimum distance from the centerline of the fasteners to the edge of the panel is / 8 inch (9.5 mm). Fastener penetration and distance to the edge of the supporting steel member must be as described in Section See Figure 7 for a typical installation detail showing one row of fasteners. Multiple rows of fasteners may be installed if required by the design.
