Top-Flange Hangers for Solid Sawn Lumber

This product's information may differ depending on the category of use. You are currently viewing details related to Top-Flange Hangers for Solid Sawn Lumber. You can also view product information related to the categories of: Top-Flange Hangers for Plated Truss, Top-Flange Hangers for Engineered Wood, Joist Framing Connectors for Cold-Formed Steel Construction

The WP is designed to support joists on purlins or beams and may be used for wood-to-wood or wood-to-steel applications. This top-flange hanger offers exceptional flexibility and versatility with the ability to be skewed up to 84° and/or sloped to a maximum of 45°. The WP is an economical choice with a low installed cost requiring only (4) nails for maximum down loads.

Key Features

  • Highly modifiable with alteration options including opened/closed top flange and offset top flange
  • Top flange may be sloped to a maximum of 35° to accommodate a sloped header
  • Features a solid one-piece top flange that provides extra stability in panelized roof applications

Material

  • Stirrup — 97 mil (12 ga.)

Finish

  • Simpson Strong‑Tie® gray paint. Some models available hot-dip galvanized; specify HDG. See Corrosion Information.

Installation

  • Use all specified fasteners.
  • The WP may be used for weld-on applications. The minimum-size weld is a 1 1/2"-long fillet weld to each side of the top flange; weld size to match hanger material thickness. See General Instructions for the Installer, note k for weld information. Weld-on applications have the maximum allowable capacity listed. Uplift loads do not apply to this application.
  • Non-modified hangers can support joists sloped up to 1/4 :12 using table loads. For joists sloping between 1/4 :12 and 3/4 :12 use 85% of the table loads. See technical bulletin Sloped Joist in Non-Sloped Hangers (T-C-SLOPEJST).
  • Web stiffeners are required for these hangers.
  • If joist is shorter than hanger by more than 1/2" use only 50% of the table loads.

Options

  • W and H dimensions are modifiable

Sloped and/or Skewed Seat:

  • May be skewed to a maximum of 84° and/or sloped to a maximum of 45°.
  • For slope only, skew only, or slope and skew combinations, the allowable load is 100% of the table load.
  • Specify the slope up or down in degrees from the horizontal plane and/or the skew right or left in degrees from the perpendicular vertical plane. Specify whether low side, high side or center of joist will be flush with the top of the header.

Load Tables

See Top Flange Hanger tables.

See Hanger Options for hanger modifications, which may result in reduced loads.

The table indicates the maximum allowable loads for WP hangers used on wood nailers. Nailers are wood members attached to the top of a steel I-beam, concrete or masonry wall.

Nailer Table

WP Nailer Table
  1. Attachment of nailer to supporting member is the responsibility of the designer.

Various Header Applications

WP Various Header Applications
  1. Code values are based on DF/SP header species.
  2. For hanger heights exceeding the joist height, the allowable load is 0.50 of the table load.
  3. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.

Modifications and Associated Load Reductions for WP/HWP/HWPH

Modifications and Associated Load Reductions for WP/HWP/HWPH
  1. For straight-line interpolation, "a" is the specified angle.
  2. Reduction factors are not cumulative. Use the lowest factors that apply.
  3. Narrow ≤ 3 1/2", Wide > 3 1/2".
  4. For type B hangers that are skewed in one direction with the top flange offset in the opposite direction, hangers 3 1/2" and narrower, the allowable load is 25% of the table load or 1,335 lb., whichever is lower, and for hangers wider than 3 1/2", the allowable load is 30% of the table load or 1,620 lb., whichever is lower.
