Patch 4.10 - Development Updates by Daidalos Team

[robtek]

In the context where i posted this its meant a SLIGHT overstress, say 5 to 10 %, for a short period of time, say 5 to 10 seconds,
as one might expect in a break turn or a pull-out.
That is a unintentional overstressing.
I believe what you wanted to say is that someone was building a roof not acoording to the expected loads,
well, thats intentional and really doesn't reflect the situation that i pictured.
Anyway, that a metal construction only sags if overstressed to the same degree as a wooden construction is very hypothetical and hard to prove.
