• Top-Flange Hangers – I-Joists, Glulam and SCL Tables

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

Nailer Table

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

1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
2. Attachment of nailer to supporting member is by the designer.
3. Steel nailer allowable loads apply to steel header material with thickness between 1/4" and 3/4" with minimum F_y = 36 ksi. Design of steel header by designer.
4. 0.157"-diameter x 5/8"-long powder-actuated fastener = PDPAT-62KP. A red (level 5) or purple (level 6) load may be required to achieve specified penetration.
5. 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.

Various Header Applications

1. This table assumes joists with F_c ⊥ = 750 psi. For other joists, check that bearing and joist nails are adequate.
2. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
3. Uplift loads are based on DF/SP lumber. For SPF/HF, use 0.86 x DF/SP uplift load.
4. Loads may not be increased for duration of load.
5. SCL (structural composite lumber) is LVL (laminated veneer lumber), LSL (laminated strand lumber), and Parallam® PSL.
6. 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.
7. DF I-joists headers include flanges made from solid sawn Douglas fir, LVL made primarily of DF/SP, or LSL. For I-joist header flanges with thicknesses from 1 5/16" to 1 3/8", use 0.85 of the I-joist header load. For I-joist header flanges with thicknesses from 1 1/8" to 1 1/4", use 0.75 of the I-joist header load.
8. 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 Reductions¹

1. Reduction factors are not cumulative. Use the lowest factors that apply.
2. Web stiffeners are required for sloped or skewed conditions.
3. For straight-line interpolation, “a” is the specified angle.
4. The sloped top flange option is permitted for BA hangers with a minimum height of 11 1/4" when the load reduction factor is applied to the tabulated BA allowable loads for the minimum installation.

Reduction Factor Instructions

Allowable Download = Lower of (Seat or Top Flange) x (Table Load)
Allowable Uplift = 0.90 x (Table Load) for BA with W < 2 1/2"
  = 1.00 x (Table Load) for all others

Sloped down and skewed left with sloped top flange Installation.
When ordering, specify low side flush, center flush or high side flush.
