I have a 9 m long glulam beam 115 * 630 that is to be mounted against a log wall. The design load at the support is 56 kN. My idea is a welded beam shoe in a heavy-duty dimension that is bolted to three logs, either with large wood screws or through bolts. Embedding the beam in the log wall is not possible in this case.
1. Is this a solution that will hold?
2. Are there other alternatives? (A column under the beam is impossible due to a door.)

Well, now we have moved on to the beam shoe, in 8 mm plate with 400 mm high sides. 7 holes on each side of the beam for a 16 mm threaded rod through the log wall. The fastening of the beam in the shoe consists of a 10 mm lag screw, 4 on each side. Welded together in a first-class manner. Now I'm not worried about the beam shoe, but rather that the log wall might be too weak... but it hardly is. Does anyone think this won't hold? Suggest something else, otherwise it goes up on the wall within two weeks.
Just as you write, the log wall will probably collapse before the beam hanger gives way. 14 through M16 is extremely generous. But definitely the right thinking, if you're unsure and building yourself, over-dimensioning is the best approach.
As long as the timber is healthy, there should absolutely be no problems! It should also be at that height, maybe you’ve already tested sticking a knife into the timber at different spots along the wall? You quickly notice if it’s good or bad then,
The timber is rock hard... smells good, fresh all the way through...
If I ever build something new from scratch, it will be timber or stone. Both are durable and wonderful building materials.
