To obtain the resistance values for a single bracket, the values in the above table should be divided by two, provided that the supported beam is locked in rotation. Please consult our ETA-06/0106 if the beam is free to rotate.

* Refer to Characteristic Capacity table columns for type of fasteners that can be used in Flange A. Capacities vary depending on fastener type used. The bolt design resistance requirement R#,d is determined from (bolt factor x connection design load F#,d) for the required load direction and fastener. Refer to the Simpson Strong-Tie anchor product range for suitable anchors. Typical anchor solutions are BOAXII, SET-XP, WA, AT-HP, depending on the concrete type, spacing and edge distances.

To obtain the resistance values for a single bracket, the values in the above table should be divided by two, provided that the supported beam is locked in rotation. Please consult our ETA-06/0106 if the beam is free to rotate.

Installation

Installation

Fasteners

On wood:

  • CNA annular ring-shank nails dia. 4.0 x 35 or dia. 4.0 x 50 mm.
  • CSA screws dia. 5.0 x 35 mm or CSA screws dia. 5.0 x 40 mm.
  • Bolts.
  • LAG screws.

On concrete:
Concrete substrate

  • Mechanical anchor: WA M10-78/5.
  • Chemical anchor: AT-HP resin + LMAS M10-120/25

Hollow masonry substrate:

  • Chemical anchor: AT-HP or POLY-GP resin + LMAS M12-120/25 threaded rod + SH M16-130 screen.

On steel:

  • Bolts diam. 10 mm

Installation

  1. Come with the joist,
  2. Add nails. It can be also screwed,
  3. If the header is made out of timber, the angle bracket can be attached to it with nails or screw,
  4. If the header is made out of concrete, the angle bracket must be attached with adapted anchors (using the installation data from the anchor)

Technical Notes

Technical Notes

F1: tensile force in the central axis of the angle-bracket
Particular situation of a fastening with only one angle-bracket:

  • If the overall structure prevents the rotation of the purlin or the post, the tensile strength is equal to half of the given value for two angle-brackets.
  • Otherwise, the connection resistance depends on the « f » distance between the vertical contact surface and the point of load application.

F2 and F3: shear lateral force
Particular situation of a connection with only one angle-bracket:

  • The resistance value to consider is equal to half of the one given for two angle-brackets.

F4 and F5: transversal force directed towards or opposite the angle-bracket

  • The connection resistance depends on the « e » distance between the base of the angle-bracket and the point of load application.
  • To consult corresponding loads, contact us.

Only F1, F2 and F3 forces for connections with 2 angle-brackets are present on this sheet.
