Design:
For the action in the direction F1 is an additional load stress F1,d from the action in the direction F4/5 added to.
For the superimposition of the actions must be proven:
Load factors for determining the bolt strength / 2 brackets per connection
| Load direction | kax | klat |
| F1 Bolt 1and 2 | 0,5 | 0,0 |
| F2/3 Bolt 1 and 2 | 0,2 | 0,5 |
| F4/5 Bolt 1 ( from F*_1,d ) | 1,0 | 0,0 |
| F4/5 Bolt 2 | 0,5 | 1 |
Proof of the fasteners in concrete / steel must be provided separately.

** 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.
*** The published characteristic capacity is based on instantaneous load duration and service class 2 according to EC5 (EN 1995) – kmod = 1,1. For other load duration and service class, please refer to the ETA to get more accurate capacities
