There is a requirement of using paired channel on top where the Profis Anchor Channel software is not allowing since the icon is dimmed with all standards. In order to model this case, I have used one single channel with edge distance equal to the edge distance of the first channel close to the edge plus half the spacing between the paired channels, and half the load (Distributed equally to each channel) as per the sketch, and the calculation attached. Please advice.
Dear Senthil,
Thanks for posting your question.
It is true the paired cast in channel option is not available in Profis under either ACI or EN. In order to design such cases, you need to individually design each one of them.
The load distribution is like below
- For the cast in channel close to edge, take half of shear with its own edge distance (100mm in this case) and distribute shear force on bolts equally. To be more conservative, take half of the spacing between cast in channels.
- For the cast in channel away from edge, take full shear force with its own edge distance (250mm in this case) and distribute it equally on bolts.
Hope that the answer to your question.

Dear Senthil,
The logic behind full shear on the rear cast in channel is 1. it is mentioned in the code, see attached screenshot 2. the holes are slotted in bracket.
So, in reality it is more conservative to assume full shear on the rear cast in channel.
This approach is only for perpendicular shear force.
Hope that the answer to your question.
Regards
Usman
