Hello.
I have a roof that extends about 2 meters from the facade, currently supported by a brick pillar and a wooden post that are embedded in the facade and rest on top of the brick pillar. The distance is about 2 meters between the facade and the pillar. Now the post has rotted, and I want to replace this post. The post is about 22 cm in diameter and looks like a felled tree that has been debarked. Now I wonder if one can easily determine how large a glulam beam I need. Would a 90x225 do the job, or do I need a thicker one?

It is entirely conceivable that the old post is oversized and that a glulam column measuring 115 x 115 would suffice. Otherwise, it should be possible to special order a glulam post in a thicker dimension. (Posts are usually square or round.)
Most evidence suggests that the old pole is overdimensioned. A normal wooden pole with a diameter of 22 cm corresponds to a glued laminated timber pole of 190x180 mm. A 2.5 m long one can bear a load of about 50 tons, which is likely not relevant. The best approach is to calculate the load conditions and select materials accordingly.
Thank you all for the help.
