Hello forum, this is a fundamental question.
It is about the fact that we are building an extension and opening an existing rafter roof on one side about 7m and will attach the new roof structure; for this, purlins must be introduced into the existing roof. The purlins should be about 40cm high. On the opposite side (to the opening), this becomes very problematic with the existing apartment, so the question is whether a purlin can also be made of steel and therefore the purlin would not have the height of 40cm???
It is clear that this must be calculated by a structural engineer!! However, the current structural engineer is somewhat complicated and does not want to know anything about it; she sees no problem that the entire existing apartment must be broken up for this... and therefore does not address my question.
So I would have to go to another structural engineer, which of course will cost money again, and before I just run off, I wanted to hear here from the experts whether this would basically be possible and what such a steel beam would look like, welded lugs.....brackets......???? The purlins would be about 7m in length and only have support points at the ends.
Regards Peter
