Attach carport with ground anchors - how to align?

For wood screws with a pointed tip, the hammer blow helps to avoid splitting the wood. When aligning the beam, wedge a strip or wedge underneath, fix it with a clamp, drill through, and fasten with screw, nut, and washers. Knock out the strip/wedge again and the beam "floats" in the beam shoe. Stability against tipping must be incorporated into the carport construction. At the bottom of the beam, these are floating bearings and not fixed bearings.

For wood screws with a point, the hammer strike helps to prevent the wood from splitting.

In principle, you are right. But with a wood screw of 10mm diameter, that is definitely not enough. I pre-drilled 8mm and used Wiener screws.

so I would have thought a screw with nuts would be the right thing for that

well, I would have thought a bolt with nuts would be the right thing for that

I thought one bolt would be too few for you. Why are 10mm holes provided there? What does the structural analysis say?

So I didn't commission a structural engineer to calculate this;-)
My plan was simply to insert a 10mm screw centered in each post. The entire post plus the proportionate roof structure rests on it. Hence my question above, whether that is sufficient. Because with an H-beam there are at least 2 such screws.

The carport manufacturer will have a structural analysis after all.
