WP/HWP/HWPH/WMU High-Capacity Top-Flange Hangers

WP/HWP/HWPH/WMU

On This Page

The WP, HWP and HWPH series are designed to support joists on wood purlins or beams. WMU hangers are designed for use on standard 8"-grouted masonry block wall construction.

The HWP and HWPH high-wind purlin hangers have enhanced uplift and are ideal for high-wind applications.

Material

  • (Top flange/stirrup): WP — 7/12 gauge; HWP — 7/12 gauge; HWPH — 3/7 gauge

Finish

  • Simpson Strong-Tie gray paint. HDG available; contact Simpson Strong-Tie.

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. For uplift loads refer to technical bulletin Top-Flange Hangers Welded to Structural Steel Members (T-WELDUPLFT).
  • 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.
  • For attaching to multi-ply headers, refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-MPLYHEADR).

Options

  • The WP, HWP and HWPH may have a sloped and/or skewed seat up to 45°. The WP may be skewed up to 84°. See Modifications and Associated Load Reductions table below.
  • The top flange of the WP, HWP and HWPH may be offset and/or sloped down up to 35°. The top flange may also be opened/closed up to 30°. See Modifications and Associated Load Reductions.
  • All models are available in Type A (joist bevel cut up to 45º). See illustration in image gallery. WP is also available in Type B style (square-cut joist). Contact Simpson Strong-Tie when ordering.
  • Hangers with a skew greater than 15° may have all the joist nails on the outside angle.
  • 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.
  • When combining skews and slopes specify whether low side, high side, or center of joist will be flush with the top of the header (see illustration in image gallery).
  • Uplift loads are not available for open/closed TF, TF sloped and offset options.

Ridge Hanger (WP only)

  • Top flange may be sloped to a maximum of 35° to accommodate a ridge (see illustration in image gallery). Specify angle of the slope. Reduce allowable load using straight-line interpolation. See open/closed example.

Codes

  • See Code Reports table below for ICC-ES ESR, City of L.A., and State of Florida

Load Tables

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

Nailer Table

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

  1. Attachment of nailer to supporting member is the responsibility of the Designer.

Various Header Applications

WP/HWP/HWPH/WMU High-Capacity Top-Flange Hangers Various Header Applications
  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. Uplift loads are based on DF/SP lumber. For SPF/HF, use 0.86 x DF/SP uplift load.
  3. LVL headers are assumed to be made primarily from Douglas fir or southern pine. For LVL made from spruce-pine-fir or similar less-dense veneers, use the values found in the SPF/HF column.
  4. WP quantity of nail holes in the top flange varies.
  5. Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
  6. For hanger heights exceeding the joist height, the allowable load is 0.50 of the table load.
  7. Fasteners: Nail dimensions in the table are diameter by length. Titen 2 screws are Simpson Strong-Tie masonry screws. 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.
Reduction Factor Instructions

Allowable Download = (lowest of Seat, Top Flange, or Joist Height) x (Table Load)
Allowable Uplift = as noted in table per height
