FCB

Roof Truss and Rafter Connectors, Ties, and Straps

This product's information may differ depending on the category of use. You are currently viewing details related to Roof Truss and Rafter Connectors, Ties, and Straps. You can also view product information related to the category: Rigid Connectors for Cold-Formed Steel Construction

The FCB clip is an economical, high-performance fixed-clip connector that can be used for a variety of framing applications. It is rated for tension, compression, shear and in-plane loads and offers the Designer the flexibility of specifying different screw and anchorage patterns that conform to desired load levels.

Key Features

  • Rated for tension, compression, shear and in-plane loads
  • Provides design flexibility with varying screw and anchorage patterns that achieve different load levels
  • Strategically placed stiffeners, embossments and anchor holes maximize connector performance

Material

  • 54 mil (16 ga.)

Finish

  • Galvanized (G90)

Installation

  • Use the specified type and number of anchors.
  • Use the specified number of #12 self-drilling screws to CFS framing. Note that #10 self-drilling screws can be used per the load tables below.

Load Tables

FC Allowable Connector Loads (lb.)

Load Table - FC Allowable Connector Loads (lb.)
  1. See General Information and Notes.
  2. FC Allowable Connector Loads are also limited by the FC Anchorage Load tables below. Use the minimum tabulated values from the connector and anchorage load tables as applicable.
  3. See installation illustrations in the image gallery for screw fastener placement to stud framing.
  4. Tabulated F1 loads are based on assembly tests with the load through the centerline of stud. Tested failure modes were due to screw pullout; therefore compare F1 against Fp calculated per ASCE 7-10 Chapter 13 with ap = 1.25 and Rp = 1.0.
  5. F1 loads are based on maximum stand-off distances of 1" or 1 1/2" as shown. Other loads are applicable to a 1" stand-off for FC32 and 1" or 1 1/2" stand-off for FC62 and FC82.
  6. The allowable plastic moment at the bend line in the F1 load direction for 97 mil (12 ga.) and 118 mil (10 ga.) FC connectors are 395 in.-lb. and 675 in.-lb., respectively.

FC Allowable Anchorage Loads to Steel (lb.)

Load Table - FC Allowable Anchorage Loads to Steel (lb.)
  1. For additional important information, see General Information.
  2. Allowable anchorage loads are also limited by the FC Connector Load table above. Use the minimum tabulated values from the connector and anchorage load tables as applicable.
  3. Allowable loads for #12-24 self-drilling screws and PDPAT powder-actuated fasteners are based on installation in minimum 3/16" thick structural steel with Fy = 36 ksi. PDPAT values are also provided for A572 steel. Values listed above maybe used where other thicknesses of steel are encountered provided that the fastener has equal or better tested values into thicker steel (see General Information). It is the responsibility of the Designer to select the proper length fasteners based on the steel thickness installation.
  4. For screw fastener installation into steel backed by concrete, predrilling of both the steel and the concrete is suggested. For predrilling, use a maximum 3/16"-diameter drill bit.

Allowable Titen HD® Anchorage Loads into Concrete with FC Clip (lb.)

Load Table - Allowable Titen HD Anchorage Loads into Concrete with FC Clip (lb.)
  1. Allowable anchor capacities have been determined using ACI 318-14 Appendix D calculations with a minimum concrete compressive strength (f'c) of 3,000 and 4,000 psi in normal-weight concrete. Tabulated values shall be multiplied by a factor (λa) of 0.6 for sand light-weight concrete.
  2. Edge distance is assumed to be 1 1/2", and end distance is 2 5/8".
  3. Load values are for group anchors based on ACI 318, condition B, load factors from ACI 318-14 Section 5.3, no supplement edge reinforcement, Ψc, v = 1.0 for cracked concrete and periodic special inspection.
  4. Allowable Stress Design (ASD) values were determined by multiplying calculated LRFD capacities by a conversion factor, Alpha (α), of 0.70 for seismic load and 0.6 for wind loads. ASD values for other combinations may be determined using alternate conversion factors.
  5. Tabulated allowable ASD loads for Wind and Seismic in SDC A&B are based on using wind conversion factors and may be increased by 1.17 for SDC A and B only.
  6. Design loads shall include the over-strength factor per ASCE7 Section 12.4.3. For fasteners in exterior wall connection systems, Ωo = 1.5 per Table 13.5-1.
  7. Allowable loads for F4 are based on the governing loading direction which is toward the edge of slab.
  8. Allowable loads for F1 are based on the governing loading direction which is toward the end of slab.
  9. For anchor subjected to both tension and shear loads, it shall be designed to satisfy the following:
    • For Na / Nall ≤ 0.2, the full allowable load in shear is permitted.
    • For Va / Vall ≤ 0.2, the full allowable load in tension is permitted.
    • For all other cases: Na / Nall + Va / Vall ≤ 1.2 where:
      Na = Applied ASD tension load
      Nall = Allowable F2 or F3 load from the FC Allowable Anchorage Loads for Concrete table
      Va = Applied ASD shear load
      Vall = Allowable F4 or F1 load from the FC Allowable Anchorage Loads for Concrete table
  10. Tabulated allowable loads are based on anchorage only. The capacity of the connection system shall be the minimum of the allowable anchorage load and the FC Allowable Connector Loads.
